Pact is the social pact app for your group. 3 to 10 people, 1 to 8 weeks. Pick a habit together: run, study, no alcohol, anything. Daily check-in. If someone fails and doesn't spend a wildcard, the whole group's streak resets to zero. Two wildcards per person. Reactions to cheer or roast. Kick votes if someone ghosts. No motivational coach, just real witnesses. iOS and Android, 17 languages. Free for up to 3 active pacts.
