Since yesterday, the really cool fork of openboard with active development and support of adding a swype library manually, got rebranded into Heliboard. A release on izzyondroidrepo and fdroid should be coming soon.
PS. If you are using the old fork you have to remove it first and do a backup of your settings.
I found that the Pixel 7 pro finally got close to an iphone 8 in terms of realistic haptic vibrations. The 6a doesnt work with florisboards “define vibration yourself” though.
So in general useful haptic vibrations like on iphones where just never there. Not sure about other brands but all android phones I had had unrealistic vibrations.
