SwiftUI iOS & Watch App -- 2

@Shaiwan

Hello, Your project is particularly interesting because the design and user flow are already validated through the interactive HTML prototype, allowing development to focus entirely on building a robust native SwiftUI experience for both iPhone and Apple Watch. I have experience developing SwiftUI applications with Apple ecosystem integrations, including CloudKit synchronization, notifications, background processing, and watchOS companion/standalone apps. For reliable background timers, I would implement a timestamp-based timing architecture rather than relying solely on active countdown processes. Combined with local notifications, background refresh mechanisms, and HKWorkoutSession on watchOS where appropriate, this ensures timers remain accurate even when the app is suspended or the device state changes. Proposed Partnership Roadmap: • Week 1: Review prototype, architecture planning, project setup • Week 2-3: Core timer engine, session logging, metadata capture • Week 4: Standalone watchOS implementation and synchronization • Week 5: CloudKit sync, WeatherKit integration, notifications • Week 6: Testing, optimization, App Store preparation I am open to discussing a partnership-based arrangement and would be interested in reviewing the prototype, market opportunity, and commercialization strategy for the UK fishing industry before defining milestone structure and revenue-sharing terms. Looking forward to learning more about the project. Best Regards Shaiwan

Hi there! Your idea is very detailed, but turning a complex iOS + Watch app into a stable native product needs careful architecture or timers and sync can easily break. Many apps fail because background execution and watch connectivity are not handled correctly. I have solid experience in Swift and SwiftUI development, including building native iOS apps with real-time features and cloud sync. I have worked with Apple Watch integrations, CloudKit, and background task handling for reliable session-based apps. I understand how to structure multi-device apps where iPhone and Watch stay perfectly in sync. I will convert your HTML prototype into a clean native SwiftUI architecture with reusable components. I will implement robust timer handling using HKWorkoutSession and background-safe scheduling for accuracy. I will ensure Watch app works independently with proper haptics, sync, and fallback states. I will design CloudKit syncing so session history stays consistent across devices without conflicts. check our work https://www.freelancer.com/u/ayesha86664 Could you please share whether the Watch app needs full offline functionality for all session logging features? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

@mutahrar

Hey, I have reviewed your requirement for a native iOS + Apple Watch app built in Swift / SwiftUI. You want to convert an existing HTML prototype into a fully native app with: iPhone + standalone watchOS app Dual countdown timers + tap counter Session logging with metadata CloudKit sync for history WeatherKit integration Haptics + audio alerts iOS 17+ support with offline watch functionality I can build this using SwiftUI + WatchKit with a clean architecture focused on performance, scalability, and reliable background execution. For background timers, I would use HKWorkoutSession on watchOS for uninterrupted execution, combined with state persistence and BGTaskScheduler on iOS. Timer state would be continuously synced via CloudKit to ensure accuracy across device transitions and interruptions. Experience links to App Store apps (including watchOS work) can be shared upon request. Timeline: Week 1: Architecture + prototype mapping Week 2–3: Core iOS + watchOS timer system Week 4: CloudKit sync + history module Week 5: WeatherKit + UI polish + haptics Week 6: Testing + App Store submission Milestones (GBP): Phase 1: Core system Phase 2: WatchOS + sync Phase 3: Final release Looking forward to exploring this partnership opportunity. Best Regards, Mutahra Rehman

What specific central metrics or main counter tools do you want to show first on your watchOS screens, what main things matter most for the CloudKit storage syncing, and do you have a preferred layout grid in mind for the historical session list? I will build your native iOS and watchOS interface from scratch using clean code structures to capture a premium fitness aesthetic without making the tracking panels look too busy or complicated. I will create a highly responsive setup using your exact interactive prototype states, making sure the dual timers, WeatherKit icons, and tap triggers look very sharp so they fit perfectly across different iPhone screens and wearable casing sizes. Sample App: https://play.google.com/store/apps/detailsid=com.applewatchforandroid.applewatchappforandroidphone_applewatchapp&hl=en I am ready to start mapping your new sports application layout today, and I want to ask if you have any current assets or legacy assets like your complete sandbox HTML files, asset catalogs, or specific color guidelines already prepared. Let us connect in the chat so you can share your working layout files, allowing me to start on the initial project architecture quickly and deliver the functional native build on time.

Hi there, A native iPhone and Apple Watch application built around reliable timing, session tracking, and cross-device synchronization requires much more than implementing screens from a prototype—this is an engineering and reliability problem, not a UI design task. Here is what I would deliver: * Native SwiftUI implementation for both iPhone and standalone Apple Watch experiences based directly on the existing interactive prototype * Shared architecture designed to keep behaviour consistent across iOS and watchOS while respecting platform-specific interactions * Reliable countdown timer system engineered for background execution using the most appropriate Apple frameworks for long-running session tracking * CloudKit integration for seamless session history synchronisation across devices * WeatherKit integration to automatically capture environmental conditions during sessions The goal is a polished native product that feels purpose-built for its audience while remaining technically reliable during long sessions — not a simple conversion of HTML screens into SwiftUI views. One quick question — does the existing HTML prototype already define all Apple Watch interactions and standalone watch workflows, or are some watch-specific experiences still open for refinement? Regards, Rajat Trivedi

@codeandcommand

The Watch app pairing is where most timelines slip. Whether you need complication support, background refresh, or just a companion view changes the build quite a bit. I work in SwiftUI and WatchOS and can start today. A focused app like this is 5 to 7 days based on scope. These numbers are based on the post as written and will adjust once we walk through the full details. Want to jump on a quick call?

@haseebs74

Hey! This is a really interesting project — a niche fishing session timer with a full prototype already done is a strong starting point for a partnership. Background timers (the hard part): For reliable background timers on iOS I'd use HKWorkoutSession on the Watch side — it keeps the app alive indefinitely without the usual background execution limits. On iPhone I'd combine BackgroundTasks with local notifications and audio session activation to ensure alarms fire even when the screen is off. The key is treating the Watch as the primary timer source and syncing state back to iPhone, not the other way around. Milestone breakdown (GBP): • M1 — Core iPhone app (timers, tap counter, session log): £X • M2 — Standalone watchOS app + haptics/audio: £X • M3 — CloudKit sync + WeatherKit: £X • M4 — Testing, App Store submission: £X Timeline: 6–8 weeks Happy to explore the partnership model — can you share the HTML prototype so I can assess scope before we go further?

Hello, As a highly experienced iOS developer, I'm excited about the prospect of partnering with you to bring this session timer and logger app to life. I've worked with Swift and SwiftUI for many years now, and have successfully deployed multiple iOS apps to the App Store. Through my extensive experience in iPad, iPhone, and Mobile App Development, iOS 17+ support, weather integration with WeatherKit, CloudKit sync, haptic & audio alarm systems. The most complex aspect of this project would arguably be implementing reliable background timers on iOS. Given that I have built various apps with similar functionalities before, including apps involving BackgroundTasks - which guarantees effective management of long-running tasks even when the app is closed - I have the in-depth understanding required to deliver optimum precision and performance. In terms of timeline and costs, I would propose a detailed milestone-by-milestone price breakdown in GBP, as well as a realistic week-by-week timeline. Having already invested my own personal time into understanding your project from your detailed HTML prototype, I am wholeheartedly committed to its success, embracing every step along the way; from accurate weather conditions to iCloud syncing for historical data. Thanks!

@SonnyDube

I am a perfect fit for your project to build a native iOS and standalone Apple Watch session timer app with seamless iCloud sync and reliable background timers. I understand the challenge of implementing background timers and notifications using HKWorkoutSession and BackgroundTasks to maintain accuracy and performance without phone dependency. My focus will be on clean implementation and smooth functionality that faithfully translates your interactive prototype into SwiftUI. While I am new to Freelancer, I have strong experience in Swift/SwiftUI and have delivered similar apps with CloudKit and watchOS support outside the platform. I offer a free consultation to better understand your goals and craft the best technical approach. I would love to chat more about your project! Regards, Sonny Dube

@harrisonm34

The biggest technical challenge in this project is ensuring the countdown timers remain accurate and reliable when the app is backgrounded, the screen is locked, or the Apple Watch is operating independently. My approach would be to use a combination of SwiftUI, CloudKit, and watchOS-native session management, leveraging HKWorkoutSession (where appropriate) and background execution mechanisms to maintain timer accuracy, synchronize session state, and deliver dependable haptic/audio alerts across both devices. What stands out about your project is that the product design work is already complete. With the interactive HTML prototype defining the screens, transitions, and user flows, the focus can remain on translating that experience into a robust native iPhone and standalone Apple Watch application rather than spending time on UI discovery. One question: does the current HTML prototype already define all timer behaviors and edge cases (pause, app termination, watch/phone sync conflicts), or would those rules be finalized during development? I'd be interested in reviewing the prototype and discussing the technical roadmap, milestones, and partnership structure in more detail.

Hi there, This is exactly the kind of project I enjoy working on. A focused, well-scoped native app with a clear niche, a complete prototype already done, and a partner who has already done the hard thinking. That combination makes for a clean build rather than a moving-target one. On background timers, which you rightly flagged as the hardest part: the approach I would take is HKWorkoutSession on watchOS to keep the Watch process alive independently of the phone, paired with a shared AppGroup container so both devices stay in sync when in range. On iPhone, BackgroundTasks with a persistent local notification acts as the fallback alarm layer. The key is never relying on a single mechanism. Timers that only work when the app is foregrounded are not timers, they are demos. I build these to survive a phone call, a lock screen, and a dead Bluetooth connection. I have shipped SwiftUI apps to the App Store and have worked with CloudKit sync and watchOS standalone sessions before. I am happy to share specifics once we connect privately, as you are keeping the brief under wraps until shortlisting, which makes complete sense for a partnership of this nature. The fishing niche in the UK is an interesting market. Loyal, community-driven, and currently underserved by purpose-built session tools. I think there is a real product here. I would like to explore this further. Looking forward to hearing from you.
