Diagnoses and prevents mobile performance regressions on every stack — Flutter, native Android, native iOS, React Native and Kotlin Multiplatform. Covers startup time, rendering and jank, memory, battery and background work, app size, the profiler and benchmark to use on each platform, and regression detection in CI. Use when an app is slow, janky, heavy or draining the battery, when setting performance budgets, or when a release must not regress.
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
# Mobile Performance One performance process for every mobile stack. This file holds the method and the budgets; each platform's profilers, benchmark harnesses and fixes live in its reference. ## 1. Pick the reference | Project | Read | |---|---| | Flutter | [references/flutter.md](references/flutter.md) | | Native Android: Jetpack Compose or Views | [references/android.md](references/android.md) | | Native iOS: SwiftUI or UIKit | [references/ios.md](references/ios.md) | | React Native or Expo | [references/react-native.md](references/react-native.md) | | Kotlin Multiplatform, shared code and hosts | [references/kotlin-multiplatform.md](references/kotlin-multiplatform.md) | | Battery drain, background jobs, wake locks, scheduled sync | [references/background.md](references/background.md) | In Flutter, React Native and KMP apps, the native reference applies to the host side of the problem: the Android or iOS process still owns startup, frame delivery and battery accounting. ## 2. Never optimize before you measure A performance task that starts with a code change is a guess. Produce these four things, in order, before touching anything: …

How to install
mdr add wrsilva/reis-mobile/mobile-performance@sha256:fdd0d961b7c6e722The line at the top of this page pins the label git:20260923.191bfd9, 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.
