DevOps Dash: practice incident response on your phone

Production is green. Your coffee is hot. Then the pager goes off.

DevOps Dash is a mobile on-call simulation built for anyone who has ever stared at an alert and thought: “Where do I even start?” Instead of reading about incident response, you run through it—alert by alert, log by log, fix by fix.

What it feels like

You step into the role of the on-call engineer. An incident lands. The clock is running. A money lost counter ticks up while you work. Your job is the same rhythm many teams know in real life:

  1. Alert — understand what’s firing and how bad it is
  2. Investigate — dig through logs, metrics-style signals, and war-room chatter
  3. Diagnose — pick the root cause that actually matches the evidence
  4. Fix — apply the right remediation before things get worse

Get it right and you contain the blast radius. Get it wrong and the outage escalates. Lives, streaks, and your score reflect how you handled the heat.

Why it’s worth a look

Realistic incident flavors

Scenarios touch the kind of pain teams see in the wild: database deadlocks, memory pressure, Kafka lag, API failures, and more—not abstract trivia.

Investigation, not guessing

You’re encouraged to read, compare clues, and reason before you commit to a diagnosis. That mirrors how good on-call work actually happens.

Difficulty that grows with you

Start at a manageable level and unlock harder shifts as you show you can finish with lives to spare.

Daily shift challenge

One run per day keeps the habit light: show up, clear a fresh incident, keep your streak alive.

Practice by stack

Want to focus on SQL, HTTP/APIs, observability, or a mixed bag? Pick practice areas on the home screen and tailor the shift to what you’re learning or refreshing.

Progress stays on your device

No account required for the core loop. High scores, unlocks, and history live locally—handy for a quick drill on the commute or between meetings.

Who it's for

  • People on call who want to stay quick when alerts fire
  • Developers who work on live apps and want safer practice
  • Students learning what happens when production breaks
  • Anyone curious about DevOps and incident response—no job title required

You don’t need years of experience. If you can read an alert and follow clues, you can play. Short sessions fit a break, a commute, or a quiet evening when you want to learn without sitting at a desk.

If you’ve ever wished you could rehearse a outage without risking a real one, this is that rehearsal—packaged as a short session you can finish on a phone.

Try it


If you give it a spin, a review on the store helps others discover it—and comments here with your favorite scenario type (DB, messaging, APIs, etc.) are always welcome.

Stay calm. Read the logs. Save the day.
