Just noticed this the other day as I switched from Heliboard to Gboard. I have the same vibration settings on both (30 ms), but Gboard just feels more responsive, while Heliboard feels kind of clunky.
Does anybody experience the same? Can anything be done about it?
But most annoying is the swipe detection, which feels much more stubborn
English is quite ok, but else... Especially mixed languages don't work well, and I'm always having to switch between German and English
Heliboard also has weird bugs such as scrubbing through text with the space not working sometimes, even duplicating letters at times.
But overall it works great.
To answer your question with another question: Heliboard isn't the same code base as GBoard, isn't it? Which means that it might have some kinks to iron out to feel more responsive.
A bit of necromancy is always appreciated. I second handed some learning about Android APIs and especially rumble.
It's really scattered and for a very specific vibration you have to basically go very low and code it yourself.
Which might be why Heliboard isn't as polished as Google Board. They might be using simpler API and Google might be using its engineering for a perfect feeling.
