Wow what an elegant design. I tried the web version from mobile even after all the warnings and it wasn’t bad at all. I’m definitely trying out the desktop versions later.
I took my iPad and a Bluetooth keyboard to try out Ensō during a hike and it worked fine. That is, until I forgot to switch off my keyboard once, put it in the backpack, and accidentally locked the device for a week!
I think one can unlock a device locked by too many password guesses by plugging it into a computer that is connected to the same iCloud account, but perhaps that feature has been removed in recent security updates.
