Friends don't let friends give up on change.
Habits that stick when a friend's on the hook too.
Most habit apps let you give up in private. Friends with Habits doesn't. Pact with a friend, check in daily, and keep each other on streak.
What it is
What is Friends with Habits?
Friends with Habits is a habit-tracking app that requires an accountability partner. Instead of tracking a habit alone, you make a pact with a friend: you both commit to the same daily habit, you both check in with proof, and you both see it when the other one misses.
It is free, made by Therr, Inc., and out now on Android through Google Play while an iOS version is in the works.
Popular pacts
Bring the challenge you're already doing.
Step goals, zone 2, cold showers, the two-minute rule. The habits everyone is talking about are better with someone on the other end. Pick one, invite the friend who's doing it too, and run it for 7 to 90 days.
- 👟 Hit 10,000 steps
- 🚴 Zone 2 cardio
- 🧊 Cold shower
- 🌅 Morning sunlight
- 🍳 Hit your protein goal
- 🍬 No added sugar
- 🫧 Sober-curious month

All of these are ready-made in the app, alongside more than 40 others. Or write your own.
How it works
Three steps. Two people. One streak.
A pact takes a minute to set up and a friend to keep. Everything else is just showing up.
-
1
Create a pact
Pick a habit — workout, reading, meditation, anything daily. Set the time you'll both show up.
-
2
Invite a friend
Send them a link. Your friend joins and becomes your accountability partner — the person who notices if you stop.
-
3
Check in daily
Add a photo or quick note as proof. Watch the streak grow together.
Why it works
Why a partner makes the difference
Committing out loud, to a person, by a set time, is one of the oldest tricks for following through. The two figures below are the ones you will see quoted everywhere; read them as the shape of the gap, not as a measurement.
With an accountability appointment. The often-quoted follow-through rate for a goal when you have a set time to report back to the person you committed to.
As an idea. The often-quoted rate for the same goal when it stays an idea you never commit to anyone. Solo apps leave you on this side of the gap; we make the other side the default.
These figures are widely attributed to the American Society for Training & Development (now ATD), but we have not been able to trace them to a published study, so treat them as illustrative. They are not measurements of this app's users. Smaller published work points the same way: in a 2015 study by Gail Matthews at Dominican University of California, people who sent weekly progress reports to a friend accomplished significantly more of their goals than people who kept their goals to themselves.
The difference
How it's different from other habit trackers
- A partner is required, not optional. Streaks, Habitify, Done and most other habit apps are built for one person. Here a pact needs two, so there is no version of the app where nobody notices you stopped.
- Check-ins carry proof. Every daily check-in takes a photo or a note, so a streak is evidence rather than a tap.
- The streak is shared. You and your partner are on the same streak, so a missed day costs both of you — the reason it is uncomfortable is the reason it works.
- It is free to start. No invite code, no card. Install it on Android and make your first pact.
- No subscription to sign up for. Free accounts track up to 3 active habits at a time, free for as long as you use it. If you want more, the first 5,000 accounts can lift that limit permanently with a one-time $20 founder unlock instead of a monthly bill.
Side by side
Friends with Habits vs. HabitShare and Habitica
All three are social. The difference is whether the other person is optional.

FAQ
Frequently asked questions
Is Friends with Habits free?
Yes. Friends with Habits is free to download and free to use, with no invite code and no card. A free account tracks up to 3 active habits at a time, with no expiry, and archiving a habit you have finished with frees its slot. Free accounts can also start a limited number of new habits each month. The optional $20 founder unlock lifts both limits.
What is the $20 founder unlock, and do I need it?
You do not need it: the free tier is free for as long as you use it, with up to 3 active habits at a time. The founder unlock is for people who want more. The first 5,000 accounts can pay $20 once and never pay again; it removes the free tier's habit limits and includes every premium feature we add later, for life. There is no subscription attached to it and nothing to cancel. You buy it inside the app through Google Play, and once 5,000 people have claimed it the offer is gone for good.
What is a pact?
A pact is a daily habit that you and a friend commit to together — a workout, a reading session, a meditation, a language lesson, anything you want to do every day. The pact holds the habit, the schedule, and the streak that the two of you share.
Do I need a friend to use the app?
Not to get started. Your first habit can run solo for a week without inviting anyone, and after that you keep checking in as soon as you have sent a single invite, whether or not your friend has accepted yet. Pacts are still the point: a pact needs two people, because solo habit trackers let you quit in private, which is the failure mode this app exists to remove. If your friend has not installed the app yet, your invite link walks them through it.
How do daily check-ins work?
Each day you check in on your pact and attach a photo or a short note as proof. Your partner sees the check-in, you see theirs, and the shared streak grows for every day you both show up. Miss a day and the streak resets for both of you.
Is Friends with Habits available on iPhone?
Not yet. Friends with Habits is on Android via Google Play today, and an iOS version is next on the roadmap. Your account works across every Therr app, so an account you create on Android will carry over. .
Who makes Friends with Habits?
Friends with Habits is built by Therr, Inc., the company behind the Therr app for local discovery and community. The two apps share one account system, so a single Therr login works for both.
