Hi there,
The AppSumo license gives access to one device at a time.
That means you can transfer your license from your phone to the web version (through your Account Manager at account.letterly.app), but it can only be active on one device at a time.
You can still read and edit your notes directly in the mobile app, or – if you prefer to work on your computer – use the integrations (for example, send your notes automatically to Google Docs) and edit them there.
If you’d like to have Letterly active on both devices simultaneously, you can simply purchase a second license.
Thank you!
