Software is never perfect. Even a seemingly work-as-intended software might have niche bug or security hole.

If you check the changelog of the software, they fix a lot of stuffs and adding more feature without making it bloated. https://github.com/Helium314/HeliBoard/releases

This thread is about virtual keyboard tho…

I use Fcitx for Android for Japanese typing.

Though, sometimes I still revert to old Mozc Android release, which not updated by Google anymore for more than five years.

OpenBoard is discontinued, the last update is from 2022.

Heliboard is continuation fork of OpenBoard, with more updates.
