I already have fully-functioning iOS and Android apps that let family members track each other’s location and start instant live-streaming chats. What I need now is a focused update that makes the experience smoother and faster on both platforms. First, the interface: the current navigation has grown cluttered, so I’d like a cleaner, more intuitive flow between home, map, and call screens. Alongside that, all icons and in-app images should be refreshed to match our new brand palette (assets will be provided). Second, performance: cold-start time must drop noticeably, in-app transitions should feel snappier, and background streaming needs to consume less battery. I’m also seeing sporadic crash reports from TestFlight and Google Play Console that I want brought down to near-zero. You’re free to work in native Swift/Objective-C and Kotlin/Java or a shared layer such as Flutter/React Native—whichever lets you hit these goals without rewriting the whole codebase. Instrumentation with Firebase Crashlytics or a similar tool is expected so we can verify improvements. Acceptance will be based on: • Average launch time under two seconds on mid-range devices • Crash-free rate ≥ 99 % over one week of beta testing • At least 15 % less battery drain during a 30-minute continuous streaming session • Updated icons and navigation live in both App Store & Play builds Source code, build instructions, and signed store-ready packages for the two platforms complete the deliverable set.

Hi, Since the iOS and Android apps already work, I'd surgically fix the hot paths instead of rewriting. Cold-start time and background streaming battery drain are two different problems — startup is usually lazy-init and asset loading, battery is the streaming pipeline and wake locks. Plan: - Profile cold start with Xcode Instruments + Android Profiler, defer SDK init off the main thread - Audit the live-streaming chats path for wake locks and decoder reuse to hit the 15% battery cut - Wire Firebase Crashlytics with proper dSYMs/ProGuard mappings, triage top crashes from TestFlight and Google Play Console - Refresh icons and tighten the home/map/call nav with your brand assets I've shipped Flutter and React Native apps with native bridges for streaming, so I'm comfortable dropping into Swift or Kotlin where the bottleneck actually lives. Is the live streaming built on WebRTC, Agora, or something custom? That changes the battery approach a lot. — Asif

Sounds like the apps have grown organically, and now the navigation and performance debt is starting to show in daily use. I’d start by mapping the current user flow across home, map, and call screens, then trimming redundant routes and consolidating state so transitions don’t reinitialize heavy views. While doing that, I’d swap in your icon set and palette so the UI cleanup happens alongside the refactor rather than after it. On performance, I’d profile cold start first, delay non-critical services, and reduce what’s being initialized before the first frame. Streaming and background tracking would be tuned to avoid unnecessary wake locks and network chatter, which is usually where battery drains sneak in. Crash logs from Crashlytics would guide the first round of fixes so we’re not guessing. I worked on an optimization pass in Zipline where we cut launch time significantly by reordering initialization and caching a few core services. Once stable, I’d validate against beta metrics before shipping.
