Sintopia

Free to start. One plan per app.

Every app starts on a free tier that is real. Three apps run on a server and have exactly one plan each; Workouts runs on your device and has none. Each plan is bought on its own site, switched on within a minute, and cancelled from the receipt.

The same rules on every site.

How a plan is bought.

On the app's own site. Payment is handled by Stripe; at checkout you enter the username of the account to upgrade, and the receipt arrives by email from Stripe.

How it is switched on.

Within a minute of the payment. In the app, open Settings and press Refresh limits.

How it ends.

Cancel any time from the link in the receipt; the plan runs to the end of the period you paid, then the account goes back to the free tier. Nothing you created is deleted. Changed your mind within 14 days? Write to us and you get the money back.

Pick the app, then the plan.

Each app site has the full pricing page with what the numbers mean.
