How you fuel.
And to how you adapt.
A journal that reads back.
A holistic view of what's working — and what's not.
Yours to keep.
Yours to share.

The quiet details.

Price.

Free to start. A premium tier exists for people who want it. The free tier is not a teaser.

Privacy.

Your timeline is yours. We do not sell your data. Ever.

Coaches.

Connect anyone you already train with. Or browse FIN-certified coaches if you want a new one.

Wearables.

Apple Health and Google Fit on day one. More to come, quietly.

No streaks. No badges. No leaderboards.

On purpose.

Have a look.

FIN is in iOS beta. The fastest way to know if it's for you is to log a day in it.
