← Keep the Diff

Unlock Premium on this computer.

You can buy Premium inside the Mac and Windows apps themselves: open Keep the Diff, click Premium, and pick a plan. This page does the same thing for anybody who would rather start in a browser. If you already subscribe on an iPhone or an Android phone, you need neither: unlock from the phone app, and pay nothing more.

First, get your code

1. Open Keep the Diff on your Mac or PC.
2. Click Premium, then Already subscribed on your phone.
3. It shows an eight-character code. Type it here.

Then choose a plan

Both cover every device you own. Cancel any time, from the receipt Stripe emails you.

Payment is handled by Stripe. Keep the Diff never sees your card. Your computer unlocks by itself the moment the payment goes through, so leave the app open.
