Accountability buddy & streaks

iPhone
Inosc is a habit app for exactly two people.
Not a feed. Not a leaderboard. One partner, five habits each, and a tree
that grows from the days you both show up.
Two trees planted close enough will fuse as they grow - their trunks join
and they share water through the roots. Botanists call it inosculation.
That is the whole idea.
HOW IT WORKS
- Pick up to five habits. Mark one as your priority.
- Invite one person. Just one.
- Tick your habits each day. So do they.
- Days you both qualify make your tree grow a ring.
- Add a photo to a habit if you want your partner to see it.
- Nudge them when they have gone quiet. Gently.
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.
Inosc Premium is an auto-renewing subscription with a 14-day free trial for
new subscribers.
After the trial:
- Solo monthly: $9.99 per month
- Annual: $59.99 per year
- Paired monthly: $7.49 per month. This price unlocks once you have grown
with a partner for fifteen days, and it is yours for good after that.
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.

Ratings & Reviews
Prices are lower. Monthly, annual and the paired rate have all come down.
The paired rate arrives sooner: seven days paired with your partner instead of
fifteen, and it no longer depends on whether you're still in your free trial.
Stay paired for a week and your monthly price drops.
Your roots now grow from the first day. Before, nothing visible happened for the
first two weeks even when you both showed up. Now every day you share moves them,
evenly, all the way to sixty.
The subscription screen has been rebuilt.
FIXED
- Editing your habits could leave you stuck. Turning one off made Save stop
working with no explanation, and a swipe could switch a habit off when you only
meant to rename it. Renaming is now a button, Save stays live and tells you
exactly what it needs, and a save that fails no longer disappears in silence.
- Looking back at an earlier day felt like the app had frozen — the rows wouldn't
respond and the week strip seemed stuck. It now shows which day you're viewing
and offers a way back to today. Tapping the same day again takes you there too.
- A day from before your habits existed showed an empty score. It now says
nothing was done, because nothing could have been.
- Invite links used to claim a code the moment they opened. They now show you
who invited you and wait for you to tap Join.
- If you're on your own, the app no longer mentions a partner who isn't there.
ALSO
- Signing out asks first, and tells you what stays on your account.
- Requests that hang now give up and offer to try again, instead of leaving you
waiting on a screen that never finishes.
- Invite links are only accepted in the form the app issues.
- Partner photos saved on your device are protected when your phone is locked.
