The challenge
The step tracking space is crowded, mostly with apps that harvest health data aggressively and push users toward subscriptions for features that should be free. The opportunity was a privacy-first alternative that respected Apple's privacy guidelines by design, not as a marketing claim.
The technical challenge: HealthKit integration with accurate step data synced across iPhone and Apple Watch, background refresh that did not drain battery, and a Watch app that felt native rather than ported. All of it built clean enough to pass App Store review on the first submission.
What we built
Stepzy is a native Swift iOS app with a companion watchOS app, built from scratch by the Suvysoft team.
Core features: real-time step counting via HealthKit, daily and weekly history, Apple Watch face complications showing live step count, and goal tracking with no account required. All health data stays on-device. No account sign-up, no tracking, no backend that holds personal data.
The privacy architecture was not a checkbox. It was a deliberate product decision that shaped every feature: what data gets logged, what leaves the device, and what the App Store listing says about data use. The App Store privacy nutrition label is accurate and shows minimal collection by design.
After launch, ASO drove growth. Keyword research targeting terms like "step counter no account," "pedometer Apple Watch," and "privacy step tracker" put Stepzy in front of the users most likely to convert and stay subscribed. Metadata, screenshots, and the app description were written for both the algorithm and the human reading the listing.
The outcome
Approved on the first App Store submission. $2,000-plus MRR within two months of launch, driven entirely by organic App Store discovery. The Watch app extended daily active usage because step data surfaced on the wrist without opening the phone. User reviews cite privacy as the primary reason they switched from other step trackers.
