1SE Pro costs $49.99 a year, or $249 once for Life of Pro, which keeps Pro on your account for good with nothing to renew. Both are on our website at me.1se.co/pro, and you can also subscribe to Pro from inside the app via the App Store or Google Play.
Every Pro plan includes 1SE Cloud Backup, unlimited projects, longer snippets, music, and everything else in What's included in Pro? You can also pay monthly when you subscribe in the app; tap Get Pro to see the price in your currency. There's no separate backup-only plan. Without Pro, 1SE is free to use with one snippet a day.
Considering a switch from your yearly plan to Life of Pro? Your payments so far won't transfer over, meaning you'll need to pay the full one-time price. To switch, cancel your yearly subscription with the provider you're billed through, wait for it to expire, then buy Life of Pro at me.1se.co/pro, so you don't pay for both at once.
