What it does

• Shows planned fasting, eating windows and time actually fasted on a calendar.
• Counts consistency, streaks and time fasted from what you record.
• Saves everything on your own device. There is no account, and you can download a backup at any time.
• Works without a connection once you have opened it, and can be installed on your phone's home screen.
