Fasting for two

Fasting is easier when someone is waiting for your check-in.

Matchly.Boo pairs you with one person — your partner, a friend, your sister — and keeps one streak for the two of you. Your fast, their fast, side by side.

Free to use. Plus covers both of you. Adults only — and never medical advice.

How it works

One streak, two people.

1

Pick your rhythm

12/12, 14/10, 16/8 or 18/6. Choose your first meal and we spell out the window in plain words.

2

Invite your person

Share one link. They sign up and you're paired — your day and theirs, side by side, with nudges when it gets hard.

3

Keep the fast, keep the streak

A timer that ends on tap, a calendar that counts, badges you earn together. One monthly freeze so a bad day doesn't erase a good month.

A timer that knows your match

See when they're fasting, how long they've been at it, and when they finish. Celebrate the days you both make it.

Habits next to your fast

Supplements, water, a walk — small daily wins that never break your streak. Share what you choose; hide what you don't.

Made for grown-ups

Adults only. A safety note before any fast. No weight-loss promises, no diets, no ads, no selling your data.

Free is the whole app for two. Plus adds unlimited habits, edits to any day in your history and all the looks — and one subscription covers you and your match. See pricing →
