Cross-platform native: React Native, Expo, Swift, Kotlin, and release ops.
React Native apps quietly balloon past 100MB and tank install rates. Here's how we audit bundle size, hunt down the real culprits, and ship a leaner binary without rewriting in Swift.
Universal Links and Android App Links still break in production more than they should. Here's a field guide for getting them right in Expo Router apps without surprising the App Review team.
How we pushed a React Native + Expo app from 99.2% to 99.9% crash-free sessions — what actually mattered, what was noise, and where Sentry, Hermes, and EAS fit in.
Background execution on iOS and Android is a minefield of OEM quirks, OS budgets, and silent task kills. Here's what survives in production React Native and Expo apps in 2026 — and what to stop trying.
Face ID and fingerprint look simple from the product side. The keychain semantics, passkey fallbacks, and review-time edge cases are where React Native teams lose a week. Here's what we've learned shipping it.
Push delivery looks fine in your dashboard but users swear they never got the notification. Here's what actually breaks push on iOS and Android in 2026, and how to debug it before support tickets pile up.
OTA updates are the best superpower Expo gives you — and the easiest way to get your app pulled. Here's how we structure EAS Update channels, staged rollouts, and rollbacks without tripping Apple's review rules.
A practical breakdown of the IAP rejection patterns we keep seeing in React Native and Expo apps in 2026 — from receipt validation to subscription restore flows — with code you can lift straight into your project.
Android 15 forces edge-to-edge by default and it's quietly breaking React Native UIs. Here's what changed, how to fix it in Expo, and where react-native-safe-area-context still gets it wrong.
An Expo app crept past 120 MB on Android. Here's the audit we ran, the libraries we ripped out, and the build flags that actually moved the needle.
Deep linking looks trivial until a marketing campaign goes live and half your users land on the App Store instead of the screen you promised. Here's what actually works in 2026.
Expo Go is great until it isn't. Here's when to graduate to a custom dev client, what breaks during the switch, and how to keep your team productive while you migrate.
Background execution is the swampiest part of mobile. Here's what actually works on iOS and Android in 2026, what Expo gives you, and where you still need a native module.
The New Architecture is the default in fresh React Native projects, but legacy apps face a real migration cost. Here's how we decide when to pull the trigger and when to delay.
Google's legacy FCM API is gone, and a lot of Expo apps quietly stopped delivering pushes on Android. Here's what actually changed, what to check, and how to wire it up properly in 2026.
OTA updates are the best and worst part of React Native. Here's how we run Expo EAS Update in production without shipping a broken JS bundle to every user at once.
A field guide to shipping subscriptions in an Expo app without getting bounced by App Review. Restore flows, paywall copy, sandbox testing, and the rejection patterns we keep seeing in 2026.
