App Development
Stepzy — iOS Fitness App
Project Overview
Stepzy is a native iOS fitness application designed and developed end to end within the Suvysoft ecosystem. It pairs an everyday step counter with an AI coach that turns raw activity data into short, personalised guidance — so people get more than numbers on a screen, they get a clear next step. A companion Apple Watch app keeps the live step count on the wrist.
Business Objective
Launch a focused, trustworthy fitness app in one of the App Store's most crowded categories — one that feels genuinely native on iPhone and Apple Watch, keeps personal health data private, and earns a place on the home screen through daily coaching rather than a wall of dashboards.
Challenges
- Standing out in a saturated step-tracking category dominated by large, data-heavy apps.
- Reading step and activity data accurately and consistently from HealthKit across both iPhone and Apple Watch.
- Designing an AI coach that gives useful, safe and non-repetitive guidance from a small set of daily signals.
- Keeping background processing and battery usage low despite continuous activity tracking.
- Passing App Store review cleanly, including Apple's health-data and privacy requirements.
Solution
Stepzy was built as a native Swift app with a companion watchOS app, reading activity directly from HealthKit and keeping personal health data on the device. An AI coaching layer converts daily and weekly trends into brief, plain-language prompts and goals. Onboarding is account-free, and the interface is built around a single clear daily view instead of a chart-heavy dashboard. The App Store listing, metadata and screenshots were written around how people actually search for a step counter.
Key Features
- Real-time step counter with daily and weekly history
- AI coach that turns activity trends into personalised, plain-language guidance
- Adjustable daily goals and streaks — no account required
- Apple Watch companion app with a live-step complication for the watch face
- On-device handling of health data for privacy
Technologies Used
Swift, SwiftUI, watchOS, HealthKit, on-device local storage, an LLM-backed coaching layer, and App Store Connect / ASO tooling.
Results
Stepzy launched as a complete iOS and watchOS product that cleared App Store review and is live at getstepzy.com. Its day-to-day value comes from coaching prompts rather than dashboards, and the account-free, on-device model lets users start in seconds.
