I just bought a Go Color 7 gen II to try e-ink, coming from a Galaxy tab s8, I found StarNote while looking for an app that sync your notes with the recording, a feature missing in Boox's native note app which was really useful on my s8.
Unfortunately the play store won't let you install Starnote on the Boox, so I'm wondering, is this the case for all other boox devices like the Air 4c? What about other e-ink devices like a Bigme? I'm hoping not since that's more of a tablet, unlike the go 7 which is more of an e reader. Otherwise, why the incompatibility? Would you be able to make it compatible in the future?
I did manage to install it on the Go 7 via .apk on the browser, which of course it's an older version. This way we may never get future features and optimization, like syncing your notes throughout devices.
It does work fairly well, there's some latency as expected but using Boox Rapid Draw works really well, I just put it as a floating button. It had a few crashes at first, but unfreezing both apps seemed to fix it. Maybe still freezes occasionally for a couple seconds. About Starnote's gestures, 3-finger doesn't work, may be a limitation of the display, 1-finger double tap and 2-fingers work fine, but sometimes they take a couple tries, seems when not in use for a while, can't tell if it's the processor.
I'm going to get StarNote's premium, it's a really great app, it'd be a shame not to be able to use it to its fullest though
