HOME / FEATURES / STREAKS
Burn keeps a longest streak and a target window streak, marks seven milestones as you pass them, and gives you two Streak Freezes a month for the days life gets in the way.
Freezes are consumed automatically. You do not have to remember to spend one, and one missed day does not erase two months of work.
The ladder
The gaps widen as the streak grows, so the next marker is never months away at the start.

Reached milestones are ticked and carry their own marker. The ones ahead show how many days are left to reach them.
Streak Freezes
Freezes exist so an unavoidable day does not end the run.
HOW MANY
Your allowance resets on the first of each month. The Streak Details screen shows how many are available and how many you have used.
HOW THEY WORK
There is nothing to tap. Miss a day and a freeze covers it, so you find out the streak survived rather than having to protect it in advance.
WHAT THEY COVER
That is the whole scope of a freeze. Your fast history is unchanged by it, and every fast you did complete is still recorded at the length it reached.
Why a streak at all
A streak measures consistency, which is the one thing a single fast cannot show you. Which pattern a person can sustain matters more than which is theoretically optimal, and that is drawn from peer-reviewed research and traced in our evidence policy.
A 14:10 day counts the same as a 20:4 day. The streak measures whether you showed up, not how far you pushed.
Longest Streak counts consecutive days with a completed fast. Target Window Streak counts the days you hit your goal length. Both sit in your twelve personal records with the dates they ran.
The current streak sits in Insights alongside completion rate and average duration, so consistency is read next to the rest of the picture.
Stop and eat if you feel unwell, whatever the number says. A freeze covers a day you cannot fast, and ending a fast early is recorded honestly rather than penalized.
Streaks, milestones and records are stored on your device, synchronized through iCloud if you enable it, and exportable as CSV at any time.
Seven milestones, two freezes a month, and a record of every run you have put together.
