Show HN: Activiews – Better visualizations for your Apple workouts

https://apps.apple.com/us/app/activiews/id6747010245
1•ahmetomer•20h ago
Hi HN!

I built the iOS app Activiews that turns your walking, running, and cycling workouts into beautiful visual maps, using data from the Apple Health app.

Activiews' Privacy & minimalism-focused features:

- 100% offline: everything stays on your device.

- No account: no registration or tracking.

- HealthKit-powered: it pulls data directly from your Apple Health.

- Map-focused: shows routes on different map styles with time, distance, calories, and heart rate stats.

It's for anyone who doesn't want to use bloated fitness apps. Looking forward to your feedback, ideas, or questions. Thank you!
