One day at a time, every time.

streaks that mean something

smart daily, weekly, and custom-frequency tracking. your streak counts the days that actually matter — not the ones in between.

Your progress. On your wrist.

complications everywhere

today's progress, glanceable on any watch face. the complication updates the moment you check off — no app open needed.

thirty-one days of drinking water. that's a habit.
a habit isn't a checkbox.
it's a small rebellion you commit, every day,
against the version of you that gives up.
build things worth keeping.
people who mean it

they show up. every day.

I check cosas from my wrist before I even reach for my phone. That single moment of friction removal changed everything for me.

Every habit app I tried felt like a chore to use. Cosas feels like something I want to open. The streak number is the first thing I see every morning.

No subscriptions, no guilt-tripping notifications, no gamification nonsense. Just my habits. It trusts me to show up — and somehow that makes me actually show up.
