Ratio, Nau is maintained by one person.
The servers, the infrastructure, and the annual store fees all come out of one developer’s pocket. If Ratio, Nau is useful to you and you want to push it forward, this is where that happens: a voluntary donation, in whatever amount you decide.
The app is free and fully usable without donating anything. A donation supports the project — it is not a purchase.
Where your donation goes
No hand-waving — this is what it costs to keep the app alive.
-
Servers and database
Hosting, backups, and syncing your recipes across devices. It gets paid every month, donations or not.
-
Services and infrastructure
The external tools and services that keep the app running day to day. Each one is metered and billed every month.
-
Annual store fees
Apple and Google charge to keep the app published. It is a fixed fee every year, before the app has earned anything.

The app is free.
No feature sits behind a wall. If you would rather not donate, the app works just as fully.
