Bluemoon1.2.0

Bluemoon lets you record period-related information on an Android device, keeping menstrual-cycle details together in one personal record. Its straightforward interface makes entering and reviewing those details uncomplicated, so you can maintain a clear history of your cycle. The design suits people who want a simple way to track their periods without handing sensitive health information to a separate service.

Recorded information can be revisited inside the app, where Bluemoon presents it as an at-a-glance overview of your cycle. Personal menstrual data stays on the device, making privacy a central part of how the Health & Fitness app handles your records. Bluemoon is open-source, with its development based on software whose source is available for examination.

Version 1.2.0 adds the ability to import existing data from Clue, which can help users bring prior records into Bluemoon. It also introduces localization, including full translations into Danish, Galician, Russian, and Spanish, plus partial translations into German, Norwegian Nynorsk, Polish, and Brazilian Portuguese. The current release requires Android 8.0 or later and supports arm64-v8a, armeabi-v7a, x86_64, and x86 architectures.
