Stronger,
together.
A private fitness pact for you and your person. Show up, share proof, and build a streak neither of you wants to break.
How it works
A pact in three steps.
Pair up
Invite your person with a private code. One pact, exactly two people — no groups, no feeds, no strangers.
Share workout proof
Snap a quick photo when you show up. Your proof goes to one person only: the one who's counting on you.
Build your streak
Hit your weekly sessions together and watch the streak grow. Miss a week, and you both feel it.
Features
Everything a pact needs.
Nothing it doesn't.
Private proofs
Workout photos shared between the two of you and no one else. Real accountability without a public audience.
Shared streaks
One streak for the both of you. Every week you both show up, it grows — and neither of you wants to be the one who breaks it.
Sparks
Celebrate a win, nudge a slow morning, or just say "proud of you." Small signals that keep both of you moving.
Custom pacts
Choose your weekly session target together. Three times a week or six — the pact is yours to define.
Membership
One plan. Two people.
One shared pact.
A single membership covers both of you. One of you joins, both of you are in — because a pact only works when you're in it together.
Privacy
Only the two of you.
VowDuo isn't social media. There are no followers, no likes, and no audience — just you and your person keeping a promise.
No public feed
Your proofs are never shown to anyone but your partner.
No strangers
Pairing works by private invite code. Nobody can find or follow you.
Your data, your pact
Delete your pact and your proofs go with it. No lingering copies.
