Period Tracker

Period tracking mobile app I built for my girlfriend. She needed a simple app to track her period cycle without all the annoying ads and premium subscription offers. Requires no internet access, all data is stored on device.

Features

• Effortless cycle logging with a clean, easy-to-use design
• Insights - average cycle and average period length
• Dynamic period prediction - smartly adjusts based on past cycles
• Static mode - set a fixed period & cycle duration for consistent tracking
• Customizable reminders - get notified n days before your period starts
• Offline data transfer between devices (for restoring data on a new device)
• Easter eggs :)

Download 

Available on Google Play Store and as a direct APK download. Not available on App Store because because fuck Apple and their $99/year membership
