Gboard was never really good at picking up strokes. Honestly, nothing ever managed to come close to the accuracy of Swype & Dragon, which is why I’m still using it even 5 years after being discontinued. You can get the apk easily, but unfortunately it won’t survive much longer when google enforces a new API version on Android.
Though I’ve heard of modded versions that should still work… Here’s to hoping. That app has been with me for 14 years.
For some reason that gave me flashbacks to Space Quest III and the Two Guys from Andromeda:
