Privacy-focused features:
• Works offline
• No account required
• Data stored on your device
• PIN lock option for added privacy

Tracking features:

• View your cycle in a calendar
• See predicted upcoming period dates
• Track symptoms such as cramps, headaches, bloating, energy, and mood

Additional tools:

• Export your records in a simple format that can be printed or shared with a doctor if needed
