Project Description
Looking for an experienced Swift / SwiftUI developer to build a focused native iOS app with a paired Apple Watch app.
The app is a session timer and logger for a specific sporting niche. Two simultaneous countdown timers, a tap counter, session metadata capture, history with iCloud sync. iPhone + standalone Apple Watch app, both built natively in SwiftUI.
A complete interactive HTML prototype already exists — every screen, transition, and state is fully designed and working. This is a translation-to-native job, not a design job. The full prototype and detailed written brief will be shared with shortlisted candidates only.
Scope summary:
Native iPhone app in Swift / SwiftUI
Standalone watchOS app (must work without phone in range)
Reliable background timers with notifications (HKWorkoutSession or BackgroundTasks)
WeatherKit integration for auto-fetched conditions
CloudKit sync for session history across devices
Distinct haptic and audio alarm patterns
iOS 17+ support
Project terms — non-negotiable:
Fixed-price, 6 milestones, payment by milestone via Freelancer escrow only
Source code lives in my GitHub repo from day one — you contribute, I own
Submission under my Apple Developer account in my company name
Final 10% held 30 days post-launch as bug-fix warranty
30 days post-launch support for critical bugs included
To bid, your proposal must include:
Links to at least two iOS apps you've shipped to the App Store (watchOS experience strongly preferred)
One paragraph on how you'd handle reliable background timers on iOS — this is the hardest technical challenge in the project
