Hi — Elias here from Miami. The real challenge here is reliable timing across iPhone and standalone Watch, not recreating the prototype UI. SwiftUI translation is straightforward; background timer accuracy, notifications, haptics/audio, and CloudKit sync are where this needs careful engineering. For timers, I would not rely on a continuously running UI timer. I’d store absolute start/end timestamps, calculate remaining time from system time, use local notifications for alarms, and use HKWorkoutSession or approved background execution patterns where appropriate to keep watchOS active during sessions. I’m comfortable working in your GitHub repo, milestone escrow, and submission under your Apple Developer account. Suggested milestones in GBP: 1. Project setup + prototype mapping: £600 2. iPhone session/timer core: £900 3. Watch standalone app: £1,000 4. CloudKit history sync + WeatherKit: £900 5. haptics/audio/notifications + QA: £700 6. App Store submission + handoff: £500 Timeline: 6–8 weeks depending on TestFlight feedback. One question: Should the Watch app support full session creation independently, or only start/log sessions from predefined settings synced from iPhone?

NATIVE iOS & STANDALONE watchOS: PRECISION TIMING & CLOUDKIT SYNC To ensure your timers never drop, we’ll utilize HKWorkoutSession on watchOS to maintain active CPU runtime and reliable haptics even when the wrist is down. On iOS, we leverage BackgroundTasks and high priority Local Notifications to trigger alarms if the app is suspended. At Plan D Studios, we bring 12+ years of experience in Swift and iOS Development, specializing in native Apple Watch standalone builds and CloudKit orchestration. Strategic Background Handling: The "hardest challenge" requires a specialized approach. For watchOS, we use the HealthKit background mode to prevent the system from suspending the timer. For iPhone, we use a combination of UNNotificationContent to ensure audio/haptic patterns fire exactly at zero, regardless of the app's state. This guarantees the sport specific precision your prototype demands. Regarding the dual timers should they trigger unique haptic signatures on the Watch so the user can distinguish between them without looking? Regards, Haider

Estimated timeline: ~5 weeks but can be discussed upon chat Estimated budget: can be discussed upon chat- split across 6 milestones If you are not happy with the work, you do not pay. We will treat it as a free consultation with no obligation. Regards Interconnect Team

@kamran2012

I can help with this, I will deliver the native SwiftUI iPhone app and standalone watchOS companion — dual countdown timers, tap counter, session logger, WeatherKit conditions, and CloudKit sync across devices. For reliable background timers, I will use HKWorkoutSession on watchOS — it keeps the app alive with an active workout session, so timers fire accurately even when the wrist drops. On iOS, I will combine BGTaskScheduler with local notifications as a fallback, ensuring alarms trigger even if the app is suspended. This two-layer approach handles the OS restrictions each platform imposes differently. Questions: 1) Do you need offline-first data persistence — local SwiftData cache that syncs to CloudKit when connectivity returns? 2) Are the haptic patterns distinct per timer, or per event type (start, warning, end)? Looking forward to your response. Best regards, Kamran
