I have a clear brief: build a fitness and wellness application that runs natively on both Apple Watch and Wear OS devices and places activity tracking—steps, distance, active minutes, calories burned—front and center. Every onboard sensor must be tapped so the data feels immediate and accurate; accelerometer, gyroscope, GPS and heart-rate readings all need to feed the activity algorithm seamlessly. The core mobile companions for iOS and Android should sync in real time, push data into Apple HealthKit and Google Fit, and show a concise dashboard that mirrors what the watch displays. I will supply the UI wireframes and branding assets; you will transform them into polished SwiftUI and Kotlin code, set up reliable Bluetooth/Companion connectivity, and guide me through TestFlight and Play Store submissions. Please include links to past work that proves you have already shipped watchOS and Wear OS apps with live sensor integration. If our conversation confirms a solid fit, we can map milestones for prototype, closed beta and public release.
