An account is what lets Hinto keep your progress — your saved words, review history and level — and sync it across devices. So if you use Hinto on more than one device, or don’t want to lose your saved words, you’ll want an account.
Signing up is quick and free. Once you have an account, everything you save travels with you — switch phones or add a tablet, and your words and progress are already there.
