Inosc is a habit app for exactly two people. Not a feed. Not a leaderboard. One partner, five habits each, and two trees that grow from the days you both show up. Two trees planted close enough will fuse as they grow. Their roots join and they share water. Botanists call it inosculation. That is the whole idea. HOW IT WORKS - Pick five habits. Mark one as your priority. - Invite one person. Just one. Or start solo and invite them when you're ready. - Tick your habits each day. So do they. - Every day you both show up, your roots grow toward each other. At 66 days, the typical time it takes for a new habit to feel automatic, they meet. - Every seven days that count add a ring to your tree. Tap your tree to see them. - Add a photo to a habit if you want your partner to see it. Photos are kept for 14 days. - Nudge them when they have gone quiet. Gently. - Sign in with Apple, Google or your email. WHY TWO Accountability collapses in a crowd. It works when one specific person notices you are missing. Inosc has no way to add a second partner, and that is on purpose. Studies back it up: people who change a habit together with a partner do better than people who go it alone. SUBSCRIPTION Inosc is an automatically renewing subscription, with a free trial of 14 days for new subscribers. Prices in the United States after the trial (the app always shows the price in your own currency): - Solo monthly: $6.99 per month - Annual: $39.99 per year - Paired monthly: $4.99 per month. This price unlocks after seven paired days, meaning days you and your partner both show up while paired to each other. Once earned, it stays yours for as long as your subscription continues. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple Account settings at any time.
