What's new

After you enter the right PIN, the app you opened now opens straight away, instead of asking for your PIN again. The lock screen text is now easier to read. Fixed a problem where a longer PIN could get stuck while you were typing it. First-time setup now clearly explains what Hisn does before anything is turned on, and lets you choose to agree or not. You stay in full control: you can turn protection off or remove Hisn whenever you want.
