How to Fix React Native Lag, Memory Leaks & Hit 60 FPS in Production

Why production React Native apps drop frames on mid-range Android devices—and the exact JSI, FlashList, Reanimated, and memory-profiling fixes used to restore locked 60 FPS fluidity.

Eliminate JS-thread frame drops by migrating heavy scroll views to recycled FlashList layouts and memoized item cells.
Stop hidden RAM spikes caused by uncleaned WebSocket listeners, background timers, and oversized uncompressed remote images.
Offload gesture & layout animations to the native UI thread with Reanimated worklets and React Native New Architecture (JSI).

Apple App Store & Google Play Submission Checklist: Preventing Rejections

Avoid costly launch delays. Learn how to prepare Privacy Manifests, In-App Purchase paywalls, account deletion flows, and background permission disclosures for smooth Apple & Google reviews.

Satisfy Apple Guideline 5.1.1(v) with a real, discoverable in-app Account & Data Deletion workflow—not just a support email link.
Write concrete, user-facing iOS Info.plist permission strings and matching Google Play Data Safety declarations.
Configure RevenueCat / StoreKit Restore Purchases, transparent subscription terms, and reviewer demo credentials prior to submission.

Founder's Blueprint: Building Scalable Apps with Expo & React Native New Architecture

Why the modern React Native New Architecture (Fabric + TurboModules) paired with Expo EAS and Supabase lets startups ship native-grade iOS and Android apps from a single TypeScript codebase.

Ship iOS and Android simultaneously from one TypeScript repository—cutting engineering cost and maintenance overhead by ~45%.
Leverage Expo Config Plugins and Continuous Native Generation (CNG) to integrate custom BLE, WebRTC, Apple Pay, and native SDKs cleanly.
Deploy instant Over-The-Air (OTA) JavaScript hotfixes via EAS Update without waiting days for store review queues.

Architecting Offline-First Mobile Apps with SQLite, WatermelonDB & Supabase

How to design resilient mobile apps that work instantaneously in underground garages, airplanes, and dead-zone highways—with deterministic sync queues and conflict resolution.

Read and mutate UI state directly against a local SQLite / WatermelonDB database for 0ms perceived latency—even in airplane mode.
Use idempotent mutation queues with UUID client keys so retried network requests never create duplicate orders or check-ins.
Combine NetInfo connectivity listeners with delta-timestamp pull/push sync to minimize cellular battery and bandwidth drain.
