The short answer
Daily Pact
Our pick★ 5.0 on the App StoreFor most couples: one private group, shared challenges, a leaderboard of two.
If you want to do a habit together and know whether the other person did it today, Daily Pact is the pick. It works across iPhone and Android, a check-in is one tap, and PactPause means a bad week for one of you doesn't wreck it for both. 14 days free with everything, then $0.99 a month.
If that doesn't fit you
- You only want to see each other's habits: HabitShare is free and does exactly that.
- Your shared goal is the gym: Sweatmates adds photo proof and wagers, iPhone only.
- You want one goal with stakes, both on iPhone: BuddyUp is free.
- You want to talk more, not track more: Paired is a relationship app, and a good one.

How we chose
We build Daily Pact, so read our pick with that in mind. Every app here was judged on the same questions: who notices when you skip, how fast the check-in is, what happens after a missed day, and what it really costs. We say plainly where another app does something we don't. The full policy is on our About page.
1. Daily Pact
Our pickA two-person group with a leaderboard of two
Daily Pact is built for groups, and a couple is the smallest group there is. You create a private group for the two of you, add the habits you want to share — gym, no phones at dinner, 10,000 steps, reading before bed — as daily or weekly challenges, and each of you checks in with one tap. The leaderboard shows both of you side by side, push notifications tell you when your partner has checked in, and PactPause lets one of you pause a challenge for a few days without breaking the other's streak. Nothing about it is couple-themed, which is the point: it treats the two of you as accountability partners, not as a relationship to be worked on.

Pros
- Rated 5.0 on the App Store
- One-tap check-in for both of you
- Daily or weekly challenges, any habit
- PactPause so a sick week doesn't end the streak
- Works across iPhone and Android, so mixed-phone couples are fine
- Add friends later without changing apps
Cons
- No free tier after the 14-day trial
- No web version
- No relationship content — it's a habit tool
3. BuddyUp
One buddy, one goal, optional stakes
BuddyUp is designed for exactly two people. You pair up, pick a goal, and track it as a streak or as a number — miles, hours, pages. You can turn a goal into a head-to-head challenge with stakes you agree between yourselves, which for a couple usually means who cooks dinner. It's free with no in-app purchases. The catch is that it's Apple-only and launched in late 2025, so if one of you has an Android phone it's out.
Pros
- Free, no in-app purchases
- Numeric goals as well as yes/no habits
- Built for pairs, so nothing is in the way
Cons
- No Android
- Very new, few reviews
- Only pairs — you can't add a friend later
4. Sweatmates
Partner workouts with photo proof and wagers
Sweatmates is a fitness-only accountability app for two. You each set a weekly workout goal, log every session with a photo through its "SweatCam", and see each other's week. You can put a wager on missed goals, appeal with a "Pinky Promise", and send nudges. It has over 10,000 App Store ratings at 4.9, so it is well past the experimental stage. It is iPhone-only and does one thing: workouts.
Pros
- Photo proof for every workout
- Wagers and nudges between partners
- Large, happy user base
Cons
- Workouts only — no other habits
- iPhone only
- Pro subscription from $4.99
5. Squad
Time-boxed challenges, free for a private pair
Squad runs challenges of one to four weeks. A private squad with your partner is free; the credits and stakes only apply to public squads with strangers. It suits couples who like a defined sprint — a 21-day no-sugar run, a 30-day walk — more than an open-ended habit. When the challenge ends, you start another.
Pros
- Private squads are free
- Structured 10, 21 and 30-day challenges
- iOS and Android
Cons
- Challenges end after four weeks
- No leaderboard or streak protection
- Public squads cost credits
6. Paired
A relationship app, not an accountability app
Paired shows up in every "couples app" search, so it belongs here for clarity. It gives you a daily question you both answer, quizzes, and guided programs on topics like money and love languages. It has over 200,000 App Store ratings. What it doesn't do is track habits or hold either of you to a goal. If what you want is to talk more, Paired. If what you want is to both go to the gym, it's the wrong tool.
Pros
- Excellent for conversation and connection
- Huge user base
- Guided programs by relationship experts
Cons
- No habit tracking or accountability
- Premium is $14.99/mo, or $39.99–74.99/yr
- Solves a different problem
7. Between
A private chat and calendar for two
Between is a private messenger with a shared calendar, photo storage and anniversary countdowns. Couples sometimes use the calendar as a makeshift tracker, which works about as well as a group chat does: fine for a week, then it fades. It's inexpensive — $2.99 a month or $26.99 for life — but it's a communication app.
Pros
- Cheap
- Shared calendar and memories
- Long-established (since 2011)
Cons
- No habit tracking
- No check-ins, streaks or nudges
- Sticker and heart purchases add up
What to do when one of you slips
This is the part no app can fix for you, but the app can make it easier or harder. A missed day between partners lands differently than between friends: it can read as "you don't care about us" instead of "you had a long day". Three rules help.
- Agree the rule before you need it. A pause, a freeze, a redo, or nothing at all. In Daily Pact that's a PactPause request the other person approves; in Sweatmates it's a Pinky Promise appeal. The mechanism matters less than having decided.
- Never make the check-in a conversation. The tap is the whole exchange. If you want to talk about why it didn't happen, do it at dinner, not in the app.
- Reset together on Monday. Streaks are motivating until they break, and then they are demotivating. A weekly challenge ("gym 3 times this week") forgives a Tuesday in a way a daily streak does not.

Frequently Asked Questions
What is the best accountability app for couples?
For shared habits and challenges, Daily Pact: create a private group for the two of you, set daily or weekly challenges, check in with one tap and see both of you on the leaderboard. It's free for 14 days and $0.99 a month after. For fitness only, Sweatmates; for a free way to just see each other's habits, HabitShare.
Is there a free accountability app for couples?
Yes. HabitShare is fully free and lets you share chosen habits with your partner. BuddyUp is free on iPhone and pairs two people on one goal. Squad is free for a private squad of two. Daily Pact is free for 14 days with everything included, then $0.99 a month.
Does it work if we have different phones?
Daily Pact, HabitShare, Squad, Paired and Between all run on both iPhone and Android. BuddyUp and Sweatmates are Apple-only, so they only work if you both have iPhones.
Is a couples app the same as an accountability app?
No. Paired and Between are relationship apps: daily questions, quizzes, a private chat and calendar. They don't track habits or hold either of you to a goal. An accountability app is about the habit, not the relationship. Many couples use one of each.
Can we add friends later?
In Daily Pact, Squad and HabitShare, yes — a couple's group can grow into a friend group without changing apps. BuddyUp and Sweatmates are built for pairs only.
