Fossify Keyboard★★★☆☆I wanted to like this keyboard, but I can’t seem to type reliably with it just by tapping on my phone, and there’s no swipe gesture or autosuggest support. It works better at tablet size.
HeliBoard★★★★☆Versatile on-screen keyboard for Android with local-only autocorrect and suggestions for multiple languages. Extremely configurable. More private than GBoard, and works better for me than Fossify Keyboard. A separate download can enable optional gesture support.
