Yes: lessons, practice and mock exams are in the Licento app for iPhone and Android, and the website is where you buy and manage your account.
licento.com sells the passes and runs your account: your purchases, your exam date, your devices and deleting your account. It has no lessons, questions or mock exams.
The app is for iPhone and Android. Sign in there with the same e-mail address as on the website — we email you a code — and your pass is there.
If you buy on licento.com, the page after your purchase takes you to the app.
