An intermittent fasting tracker that starts on schedule
Balnc’s fasting tracker times your fast with presets for 16:8, 18:6, 20:4, 24, 36, 48 and 72 hours, or any custom length up to 168 hours. Choose the days you fast and a start time, and Balnc starts each fast automatically in your time zone and ends it when you reach your target.

How does automatic fasting work?
Choose which days of the week you fast and set one start and end time for them. Balnc checks every hour and starts your fast at the right moment in your own time zone, then ends it automatically once you hit your target, so you never have to remember to press start.
What can I log during a fast?
Rate your mood, hunger and energy from 1 to 5 and add notes. Over time these check-ins show how different fast lengths actually feel for you.
How does fasting connect to the rest of Balnc?
