Hi, This is a really interesting concept—I’d love to help you build a precise, offline-first passive split timer for watchOS with a seamless iOS companion. I have 8+ years of experience in iOS development, including SwiftUI, CoreMotion, and full App Store deployment workflows. **How I’ll approach your app:** **watchOS App (Core Focus)** * Passive split detection using CoreMotion (accelerometer + motion patterns tuned for running) * Smart filtering to reduce false positives and ensure reliable split triggers * Instant haptic feedback using CoreHaptics (≤0.2s response target) * SwiftUI-first interface optimized for glanceability * Full complications support (modular, circular, utilitarian, etc.) within system refresh limits **iOS Companion App** * Shared SwiftUI architecture where practical * Workout history, analytics, and settings * Offline-first sync using CoreData + CloudKit with automatic conflict resolution * Background sync handling for seamless data consistency **Delivery Includes** * Complete watchOS + iOS apps (SwiftUI only, no storyboards) * App icons, screenshots, and store assets * TestFlight setup and full App Store submission for both apps * Support through review until approval If you’d like, I can first prototype the motion detection logic to validate split accuracy before full development. Looking forward to working together on this—it's a great use of Apple Watch capabilities. Best regards Sushma

Eid Mubarak! Most fitness and sports apps don't fail because the idea wasn't good they fail because the interaction model asks too much of the user at exactly the moment they have nothing left to give. Here's what I'm proposing: starting from the watchOS side, I'd build the auto-split logic so movement alone drives every decision, with haptic confirmations that feel like a quiet acknowledgement rather than an interruption. Rich complications surface current split progress on any watch face without the user ever opening the app. The iOS companion handles what the watch shouldn't history, settings, and the CoreData sync layer that keeps workouts intact whether the devices are talking to each other or not. Offline-first means the watch works in a tunnel, a basement, or the middle of nowhere, and the moment connectivity returns, everything reconciles cleanly.. Let's connect so we can discuss further

@SalinaSof30

Hello, My self Sukarti and I am iOS & watchOS Developer, with 8+ years of experience in Swift and SwiftUI, and I can help you build your native watchOS app with passive motion-detection timer splits and the companion iOS app. I see, you need a seamless offline-first experience where the Apple Watch detects movement automatically to trigger splits with subtle haptic feedback, while the iPhone app manages history, settings, and background sync using CoreData and CloudKit. I can also handle App Store assets, provisioning, TestFlight builds, and final submissions for both devices. So from my side, I can develop these modules for you: Modules: User Side: * Passive motion-detection split timer * Haptic feedback for each split * Rich watch complications * Offline-first sync with iPhone Admin Side: * iOS companion for data review and settings * CoreData + CloudKit sync management * App Store submission and TestFlight builds * Conflict resolution and background sync logic Deliverables: => Unlimited Revisions => ON TIME DELIVERY => 40 hr/week Lets connect to discuss more. Thanks Sukrati

Hello, With extensive experience in developing native watchOS applications using SwiftUI, I am confident in delivering an innovative passive split timer that seamlessly integrates motion detection, haptic feedback, and rich complications. My approach ensures the app is offline-first, reliable under typical running conditions, and syncs effortlessly with the iPhone counterpart. What are the specific performance benchmarks you expect for passive motion detection accuracy under various outdoor conditions? Thanks, Juan Aponte

@Visharaa2024

I’m a Swift and iOS/watchOS developer with strong experience building SwiftUI-based, offline-first applications and working with CoreMotion, CoreHaptics, CoreData, and CloudKit. I understand the goal of creating a passive, motion-driven splitting system on Apple Watch, and I can implement accurate accelerometer-based detection with low-latency haptic feedback, while ensuring efficient battery usage and reliable background processing. I will design a clean, shared SwiftUI architecture across watchOS and iOS, with robust offline-first sync, conflict resolution, and seamless data flow between devices. The watch app will include responsive complications that respect system limits, and the iOS companion will focus on history, settings, and data synchronization. I can also handle TestFlight builds, App Store submission, and ensure the app meets review guidelines. My focus is on building a stable, performant, and well-structured solution that delivers precise split detection and a smooth user experience across both platforms.
