One subscription covers every device you own: iPhone, iPad, Mac, Apple Watch, Windows, Android and Wear OS.

Buying here is cheaper than buying in an app store, and it is the same subscription. A sale on this page pays no platform commission, so the difference goes to you rather than to Apple or Google.

How buying here works

Payment is handled by Stripe on their own page, so no card details ever reach Keep the Diff. Then the subscription has to be attached to the app on your computer, which takes one step:

  1. Open Keep the Diff on your Mac or PC and click Premium.
  2. Pick a plan there and pay. The app unlocks itself the moment the payment lands.

Prefer to start in the browser? Use the unlock page: the app shows an eight character code, you type it there, and it unlocks the same way.

Already subscribed on your phone?

Then you have already paid for every device, and you should not buy anything on this page. Open Keep the Diff on your iPhone or Android phone, go to Settings → Plan → Unlock on my computer, and type in the code your Mac or PC is showing. There is no second charge.

Canceling

Bought here, cancel from the receipt Stripe emails you, any time, and Premium runs to the end of the period you paid for. Bought in an app store, cancel in that store's own subscription settings, because Apple and Google hold the subscription rather than us.
