It’s 2:37 AM. The world is quiet, but your phone shrieks with the fury of a thousand dying servers. You fumble for it, eyes blurry, heart pounding. It’s the dreaded on-call alert. For a DevOps or SRE engineer, this isn't just a notification; it's a call to action, a race against time where every second impacts the business and your sanity.

In the past, this moment meant a frantic rush to a laptop. But in 2025, the game has changed. Your smartphone is no longer just the alarm bell; it's your primary incident response command center. With the right suite of mobile apps, you can diagnose, communicate, and even resolve many issues before your coffee maker has finished its brew. This isn't about replacing your workstation; it's about empowering you to be effective from anywhere, turning moments of high stress into controlled, efficient resolutions.

This guide is your new on-call playbook. We've curated the top 19 mobile apps that every DevOps engineer needs to master. From receiving the initial red alert to communicating the final "all-clear," these tools will transform your on-call experience from a reactive nightmare into a proactive, managed process. Let’s gear up and turn your phone into the ultimate SRE sidekick.


Alerting & Incident Management

These are the first responders in your digital toolkit. They wake you up, give you context, and let you take initial command of the situation.

1. PagerDuty: The On-Call Lifeline

If you're on call, you likely know PagerDuty. It's the industry-standard for aggregating alerts and managing on-call schedules. Its entire purpose is to ensure the right person gets the right information at the right time, no matter what.

The mobile app is where PagerDuty truly shines for the engineer in the field. It’s far more than a glorified pager. You can view rich alert details, acknowledge to let your team know you're on it, re-assign if you're not the right person, or even trigger predefined incident response plays directly from the app. This is your first port of call to triage an incident and decide if it’s a “roll over and go back to sleep” or an “all hands on deck” situation.

  • Pro-Tip: Customize your notification rules and sounds. Set a less jarring tone for low-priority warnings and reserve the most alarming sound for critical, customer-facing outages. This simple trick can save you countless adrenaline spikes.

2. Opsgenie: The Atlassian Powerhouse

A powerful competitor to PagerDuty, Opsgenie (now part of Atlassian) offers robust alerting, on-call scheduling, and incident management. Its deep integration with the Atlassian ecosystem—Jira, Statuspage, and Bitbucket—makes it a no-brainer for teams already invested in those tools.

The Opsgenie mobile app provides a clean, intuitive interface for managing the entire incident lifecycle. A standout feature is its ability to easily create conference bridges and Slack channels directly from an alert, streamlining the communication process from the very first moment. You can also run post-incident reports and analytics from your phone, making it easy to review what happened while the details are still fresh.

  • Example: You receive an alert for a database connection pool exhaustion. From the Opsgenie app, you can acknowledge it, tap to create a dedicated #incident-db-2025-03-15 Slack channel, and invite the database team to join the call, all within 30 seconds.

3. Grafana OnCall: The Open-Source Champion

For teams that live and breathe the Grafana stack (Loki, Mimir, Tempo), Grafana OnCall is a fantastic, open-source-friendly choice. It integrates seamlessly with your existing Grafana dashboards and alert rules, creating a unified observability and response platform.

Its mobile app focuses on simplicity and speed. It allows you to manage alerts with straightforward swipe gestures to acknowledge, resolve, or silence. The real power comes from the deep links back to your Grafana dashboards. An alert doesn't just tell you something is wrong; it gives you a one-tap path directly to the relevant dashboard on your phone's browser, letting you see the failing metric in context immediately.

  • Pro-Tip: Use Grafana OnCall's flexible escalation chains to automatically group related alerts. This prevents "alert storms" on your phone when a single upstream failure triggers dozens of downstream alarms.

4. Datadog: The All-in-One Observability Hub

Datadog is more than just an alerting tool; it's a comprehensive observability platform that brings metrics, traces, and logs together. The mobile app is a surprisingly powerful window into this vast sea of data, making it invaluable for on-the-go investigation.

While you won't be writing complex queries, the Datadog app is perfect for quickly checking pre-built dashboards, viewing service-level objective (SLO) statuses, and diving into individual host metrics. You can see active monitors, check for anomalies, and get a high-level overview of your entire stack's health, all while waiting in line for a coffee. As Goh Ling Yong often emphasizes, having this level of context at your fingertips is crucial for rapid decision-making.

  • Example: An alert fires for high latency in your checkout service. You open the Datadog app, pull up the service dashboard, and see a spike in errors correlated with a recent deployment. You now have a primary suspect before you've even opened your laptop.

Communication & Collaboration

An incident is a team sport. These apps are your digital war rooms, ensuring everyone is on the same page from start to finish.

5. Slack: The Digital War Room

Slack is the central nervous system for many tech companies, and during an incident, it becomes the indispensable war room. The mobile app ensures you are never disconnected from your team, even when you're away from your desk.

Beyond simple messaging, the Slack app's power lies in its integrations. Chatbots can post alerts from PagerDuty, push deployment status from Jenkins, or allow you to run simple diagnostic commands via a tool like Hubot. Features like Huddles (for quick audio calls) and dedicated incident channels (e.g., #inc-auth-service-down) keep communication focused and documented.

  • Pro-Tip: Set up keyword notifications for terms like "production down," "P1," or your primary service's name. This ensures you see critical messages even if a channel is muted.

6. Microsoft Teams: The Enterprise Command Center

For organizations standardized on the Microsoft 365 suite, Teams is the go-to collaboration hub. Like Slack, its mobile app is critical for on-call incident communication and coordination.

Where Teams excels is its native integration with the Azure ecosystem. You can embed Azure DevOps Kanban boards into tabs, get alerts from Azure Monitor directly in a channel, and leverage Power Automate to create workflows that connect your response actions with your infrastructure. The app's robust file sharing and threaded conversations help keep incident-related artifacts organized.

  • Example: An Azure Function is timing out. An alert is posted to your on-call Teams channel. You start a video call within the channel, share your screen from your desktop, and walk through the Application Insights logs with a colleague who joined from their phone.

7. Discord: The Real-Time Voice Specialist

Once just for gamers, Discord has become a popular choice for tech teams, particularly those who value high-quality, always-on voice communication. Its mobile app is lightweight, fast, and exceptionally good at audio.

During a high-stakes incident, typing can be too slow. Discord's main advantage is its "voice channels," which act like an open conference call that team members can drop in and out of as needed. This creates a low-friction environment for real-time brainstorming and coordination that can be much faster than typing updates in a text channel.

  • Pro-Tip: Create a dedicated "On-Call War Room" voice channel. When a major incident kicks off, everyone involved can immediately join from their phone or desktop to sync up, eliminating the need to set up a formal meeting.

Monitoring & Dashboards

"Is it just me, or is the site down?" These apps help you answer that question with data, not guesses.

8. Grafana: Your Dashboards on the Go

If your team uses Grafana, having the mobile-friendly web interface is essential. While there isn't an official dedicated app, the web UI is responsive and bookmarking your key dashboards to your phone's home screen is the next best thing.

Being able to quickly pull up your primary service health dashboard from your phone is a superpower. You can spot trends, confirm whether a metric has breached its threshold, and correlate events across different systems. It's perfect for a quick "gut check" to see if an alert is a transient blip or the start of a serious problem.

  • Example: You get a CPU alert for a Kubernetes pod. Before escalating, you open your bookmarked Grafana dashboard for that namespace, see that memory usage is also spiking, and realize it's likely an OOM (Out of Memory) loop, not just a CPU issue.

9. New Relic: APM in Your Pocket

New Relic provides deep insights into your application's performance (APM). Its mobile app distills this complex data into a digestible format, making it perfect for on-the-fly performance analysis.

The app lets you check your application's Apdex score, error rates, and transaction traces. You can drill down into a specific slow transaction and see exactly which database query or external API call is the bottleneck. This is invaluable for quickly distinguishing between an infrastructure problem and a code-level performance regression.

  • Pro-Tip: Set up key transactions in New Relic for critical user flows (e.g., "User Login," "Checkout Process"). When an issue arises, you can check these specific transactions on the mobile app first to immediately gauge customer impact.

10. Kibana: Sifting Through Logs

Like Grafana, Kibana's power is best accessed via its responsive web interface on your mobile browser. For teams using the Elastic Stack (ELK), Kibana is the window into your logs.

While you won't be performing complex Lucene queries on your phone's keyboard, the mobile view is excellent for viewing pre-configured dashboards and discovering recent error logs. You can quickly filter by time, search for a specific transaction ID provided in an alert, and see the surrounding log entries for context. This can often be the fastest way to find a revealing stack trace or error message.

  • Example: A user reports an error with a "Correlation ID." You paste that ID into the Kibana search bar on your phone and instantly see all the logs from every microservice associated with that user's request, revealing the point of failure.

Cloud & Infrastructure Management

Sometimes, you just need to turn it off and on again. These apps give you direct, secure access to your cloud infrastructure.

11. AWS Console: The Cloud in Your Hand

The AWS Console mobile app gives you a surprising amount of control over your AWS resources. It’s an essential tool for any engineer working in the AWS ecosystem.

From the app, you can view the health of all AWS services in a given region, check on CloudWatch alarms, and even perform basic actions like stopping, starting, or rebooting an EC2 instance. You can also view basic resource configurations and metrics, which can be a lifesaver for confirming if a server is running or checking a security group rule without needing a laptop.

  • Example: A PagerDuty alert fires for an unresponsive web server. You open the AWS Console app, navigate to the EC2 instance, see that it failed its health check, and trigger a reboot. The entire incident is resolved in under two minutes, from your couch.

12. Azure App: Managing Your Microsoft Cloud

For those on the Microsoft side of the cloud, the Azure app provides similar on-the-go management capabilities for your Azure resources.

The app's dashboard is customizable, allowing you to pin the resources you care about most—like a critical App Service, a Kubernetes cluster (AKS), or a Cosmos DB instance. You can monitor health and metrics, get push notifications from Azure Monitor, and run basic commands using the mobile Cloud Shell. It’s a powerful tool for quick status checks and minor interventions.

  • Pro-Tip: Use the mobile Azure Cloud Shell to run pre-written scripts stored in your cloud shell storage. This lets you execute complex but routine diagnostic or remediation tasks with a single command from your phone.

13. Google Cloud Console: GCP on the Move

Google Cloud users aren't left out. The Cloud Console app provides a streamlined view of your GCP projects, billing information, and incident status.

Its strongest feature is the tight integration with Google Cloud's operations suite (formerly Stackdriver). You can view and manage incidents, check logs, and see performance dashboards. Like its competitors, it also lets you perform basic actions on resources like Compute Engine VMs and check the status of GKE clusters.

  • Example: You need to verify if a recent deployment to a GKE cluster has completed successfully. You can open the app, navigate to the cluster, and check the status of the workloads without needing to run kubectl commands.

14. Kubenav: Your Kubernetes Swiss Army Knife

Managing Kubernetes from a phone sounds daunting, but kubenav makes it surprisingly manageable. This app provides a clean, mobile-native UI for interacting with your K8s clusters.

After configuring your kubeconfig, you can use kubenav to check the status of pods, deployments, and services across multiple clusters. You can view resource YAML, check logs for a specific pod, and even exec into a container for quick debugging. It's the closest you can get to having kubectl in your pocket. I've found this app, as mentioned by my colleague Goh Ling Yong, to be a real game-changer for K8s-heavy environments.

  • Pro-Tip: Use the favorites feature in kubenav to bookmark your most critical production pods or deployments. When an alert comes in for that service, you can get to its logs in just two taps.

Remote Access & Execution

When dashboards and APIs aren't enough, you need to get your hands dirty. These apps provide a secure shell.

15. Termius: The Modern SSH Client

Termius is a beautifully designed, cross-platform SSH client that is perfect for on-call work. It securely syncs your hosts, keys, and settings across all your devices (desktop and mobile).

The mobile app is a joy to use. It features a special keyboard with easy access to common characters like tab, ctrl, and arrows. You can save snippets of frequently used commands (docker ps, sudo systemctl restart nginx) and run them with a single tap. It also supports Mosh for stable connections on flaky mobile networks and port forwarding for securely accessing internal web UIs.

  • Example: You need to clear a cache on a server. You open Termius, tap on the saved host, use your fingerprint to authenticate, and tap your "Clear Cache" snippet. The problem is fixed in less than a minute.

16. Royal TSi (for iOS) / JuiceSSH (for Android): Powerful SSH Alternatives

While Termius is a great cross-platform choice, it's worth mentioning platform-specific powerhouses. Royal TSi for iOS is a feature-rich client that integrates with password managers and supports a wide array of connection types beyond SSH.

On the Android side, JuiceSSH is a long-standing favorite known for its slick terminal emulation, plugin support, and excellent keyboard pop-up design. It makes typing complex commands on a small screen far less painful. Having a reliable SSH client is non-negotiable, and these apps deliver.

  • Pro-Tip: Whichever SSH client you choose, pre-configure all your critical hosts and authentication methods before you go on call. Fumbling with IP addresses and private keys at 3 AM is a recipe for disaster.

Security & Utilities

These are the unsung heroes of your on-call toolkit, providing the secure access and information you need to use all the other apps.

17. Authy / Google Authenticator: Your Digital Keyring

In 2025, if your critical infrastructure isn't protected by Multi-Factor Authentication (MFA), you have bigger problems. An authenticator app is an absolute necessity for securely logging into your cloud provider, VPN, and other sensitive services.

Authy is often preferred for on-call work due to its multi-device sync and encrypted cloud backups. If you lose or break your phone, you won't lose access to all your 2FA tokens. Google Authenticator is simpler but ties tokens to a single device. Whichever you use, it's the gatekeeper to your entire on-call toolkit.

  • Pro-Tip: If you use Authy, install it on a secondary device like a tablet and keep it at home. This provides a backup in case something happens to your primary phone during an incident.

18. 1Password / Bitwarden: The Secure Vault

You should not be storing production passwords in your notes app. A dedicated password manager is critical for securely storing and accessing the credentials you need to do your job.

Mobile password manager apps like 1Password and Bitwarden use biometrics (fingerprint or face ID) to give you fast, secure access to database passwords, API keys, and service account credentials. They can autofill logins in your mobile browser and other apps, saving you from typing long, complex passwords on a tiny keyboard.

  • Example: You need to log into a third-party provider's web dashboard to check their service status. You open the site in your browser, and your password manager app prompts you to autofill the username and complex, 32-character password with a single tap.

19. Statuspage: The Ultimate Gut Check

Sometimes, the problem isn't you—it's one of your upstream dependencies. The Statuspage app (another Atlassian tool) lets you subscribe to and get push notifications for the status pages of critical services you rely on, like AWS, GitHub, Cloudflare, or Stripe.

This can be the fastest way to confirm if you're dealing with an internal issue or a widespread external outage. The app also allows you to update your own company's status page, providing a quick way to communicate with your customers during an incident and letting them know you're on the case.

  • Pro-Tip: Pre-subscribe to every single critical third-party service your application depends on. When an alert comes in, the first thing you should do is glance at your Statuspage notifications to rule out a larger, external problem.

From Red Alert to Resolved

Being on call will always have its stressful moments, but it doesn't have to be a chaotic scramble in the dark. By curating your own 'Red-Alert-to-Resolved' toolkit on your smartphone, you empower yourself to be a more effective, efficient, and less-stressed engineer. These 19 apps form a comprehensive mobile command center, allowing you to triage, communicate, investigate, and even resolve incidents from anywhere.

Mastering these tools is an investment in your own well-being and your company's reliability. The goal is to make your on-call shifts smoother, your Mean Time to Resolution (MTTR) shorter, and your 3 AM wake-up calls a little less daunting.
