HP Prime App Gone from Android Store

[serdasteclas]

I have noticed that the app is not available on the Google Play Store (Android) for a few months now. I have posted about this on Reddit and some users commented that the app sometimes disappears only to reappear a few days later, that does not seem to be the case. That is very disappointing as my phone is almost the size of the calculator and my intention was to buy the pro version for when I don't have the calculator with me. I did find the pro version apk on some very sketchy websites but I can't enable unsigned apps on my phone due to security policies at work. Does anyone knows any "legit" appstores where the app is available? like amazon appstore or samsung galaxy store?

This thread suggests that if you have an APK on one mobile it can be copied, though that might not meet your security requirements.
It also mentions an alternative app site for the Lite version.

I haven't tried either.

Even copied APKs are generally still signed so you should still be able to install it even if you are not able to install unsigned APKs.
