Fastalune

Fastalune is a fasting timer and private journal for your daily routine. Start a session, choose a preset or custom goal, and end it whenever you choose. The timer uses your saved start time, so you can close the app and return later. Review your history, edit a session, or add a note, mood, or optional weight. Log a daily check-in and set local reminders that fit your schedule. Your records stay on your device. No account is required. You can export a local backup and restore it when you need it. Fastalune tracks time for personal use. It is a lifestyle tool and does not provide medical advice.

A charcoal and blue design throughout Fastalune, including the timer, journal, reminders, settings and dialogs. Set local reminders with quiet hours and choose from 38 offline languages. Your fasting records stay on your device.
