Heart Rate Zones Plus – The first iOS app I developed

Hacker News

I built this iOS app because I wanted to get an overview of my time in zones per week without checking zones after every workout manually - Now I'm looking for feedback. Description: Track time in heart rate zones. Track per day, week, month, 7 days and 30 days time period and how much time you spend in each zone. Set goals & visualize progress. Get details about heart rates zones of your workouts. Features: Custom time periods, Workout to zone attribution to get a feeling which sport attributed most to each zone, Multiple zone calculation methods, Set personal time goals for any zone, Workout breakdown Pricing: Free Privacy: Nothing is tracked or send somewhere. Data is just on your device. Any feedback and features request is appreciated. Download: https://apps.apple.com/us/app/heart-rate-zones-plus/id674474... Video of the app in action: https://www.youtube.com/shorts/-qtHxEdMEv0
