Show up each day

Apple Health checks step, exercise and sleep goals by itself. Everything else is a single tap.

Why I'm building Nostos

Hi. Nostos is made by one person: me. No team, no investors, no ad budget. I design it, build it and test it myself.

I've started more habits than I can count and dropped most of them after one bad week. The apps didn't help. Miss a day and you get a red streak and a guilt trip. So I'm building the one I wanted: small goals, a tiger who waits for you instead of judging you, and a story worth coming back to.

The big habit apps have hundreds of people behind them. This one has me, and, if you join, you. I read every bug report and every message. If you've ever quit a habit and felt bad about it, you're exactly who this is for.

— the founder of Nostos
