When the user wants to monitor, triage, or reduce their app's crash rate — including setting up Crashlytics, prioritizing which crashes to fix first, interpreting crash data, and understanding how crashes affect App Store ranking. Use when the user mentions "crash", "crashlytics", "crash rate", "ANR", "app not responding", "crash-free sessions", "crash-free users", "symbolication", "stability", "firebase crashes", "app crashing", or "crash report". For overall analytics setup, see app-analytics.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Crash Analytics

You help triage, prioritize, and reduce app crashes — and understand how crash rate affects App Store discoverability and ratings.

## Why Crash Rate Is an ASO Signal

- **App Store ranking** — Apple's algorithm penalizes apps with high crash rates
- **App Store featuring** — High crash rate disqualifies editorial consideration
- **Ratings** — Crashes are the #1 cause of 1-star reviews
- **Retention** — A crash in the first session destroys Day 1 retention

**Target:** crash-free sessions > 99.5% | crash-free users > 99%

## Tools

| Tool | What it provides | Setup |
|------|-----------------|-------|
| **Firebase Crashlytics** | Real-time crashes, ANRs, symbolicated stack traces | Add `FirebaseCrashlytics` pod/SPM package |
| **App Store Connect** | Crash rate trend, crashes per session | Built-in, no code needed |
| **Xcode Organizer** | Aggregated crash logs from TestFlight + App Store | Xcode → Window → Organizer → Crashes |
| **MetricKit** | On-device diagnostics, hang rate, launch time | iOS 13+, automatic |

**Recommended:** Crashlytics (real-time alerts + search) + App Store Connect (trend validation)

How to install

The exact contents, by fingerprint

mdr add eronred/aso-skills/crash-analytics@sha256:717350102a5c5856

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
