Stability

Enough with crashes nobody prioritizes.

For internal mobile teams after a Play Vitals warning or a rating decline, where crash tickets keep getting deprioritized under feature pressure. In one week, I set up or clean up crash monitoring, identify the top crash clusters, and fix the biggest causes as merge-ready PRs — measurable through the crash-free rate.

For engineering leads and CTOs with an internal mobile team

The crash-free rate is directly tied to rating, retention, and store visibility, a measurable KPI that justifies the budget internally. The team knows the crash numbers or suspects them, but can't get the topic prioritized alongside feature pressure.

„Play Vitals aren't a vanity metric: above the bad-behavior thresholds, Google visibly penalizes your store reach, and crashes are the most common reason for 1-star reviews.“

Step 1

Check the data situation

Are Crashlytics or Sentry in place and configured cleanly? If not, day 1 is instrumentation — otherwise there's nothing to prioritize.

Step 2

Prioritize clusters by user impact

I analyze Play Vitals and crash data and prioritize clusters by affected sessions, device classes, and app versions.

Step 3

Isolate root causes

I reproduce the top clusters and isolate the root causes, instead of just catching symptoms.

Step 4

Fixes as merge-ready PRs

I fix the root causes as merge-ready PRs with explanations, including regression tests wherever it makes sense.

Step 5

Alerting & release health dashboard

I set up thresholds and a dashboard, so the next regression gets caught before the reviews report it.

Step 6

Closing review & follow-up measurement

I discuss the root-cause patterns with the team (knowledge transfer) and hand over the prioritized remaining list. After the next release cycle, a follow-up measurement produces the before/after report.

What you get

  • Before/after Vitals report
  • Merged or merge-ready fixes for the biggest crash causes
  • Cleanly set up crash monitoring and alerting
  • Release health dashboard
  • Prioritized remaining list
  • Closing review with knowledge transfer

The success metric is the data-based reduction of the addressed crash clusters. The sprint addresses the biggest clusters; everything else I hand over as a prioritized remaining list.

Foundation or Full Sprint: what do you need?

The Foundation is a real deliverable, not a knowledge product — monitoring is running, alerts are set, clusters are prioritized by user impact. It's enough if your team can take on the fixes themselves and just lacks the clean data foundation and root-cause isolation. The Full Sprint additionally delivers fixes for the three biggest crash causes as merge-ready PRs, plus the follow-up measurement after the next release. You don't have to decide upfront: the Foundation feeds into the Full Sprint, and you can commission the fix stage afterward.

The details

Foundation
€2,900 excl. VAT. Crash monitoring and alerting cleanly set up, cluster analysis by user impact, prioritized remaining list.
Full Sprint
€6,900 excl. VAT. Foundation plus fixes for the three biggest crash causes as merge-ready PRs, with follow-up measurement after the next release.
Time investment
3–5 days
What I need
Access to code, Play Console, and a crash tool, or a willingness to set one up; for agency-built apps, the agency's cooperation.
