From iOS to Android

Hello,

I have recently switched from iOS to the Android ecosystem. I had the lifetime license on iOS and from what i read on the forum here, is that i need to purchase a new license for Android. Is this still a thing or there is a universal license nowadays? (cause most posts were dated 2-3 years ago)

Also on Android i checked there is a normal and a lite version, what’s the difference between them?

Last but not least in iOS i was able to test the app and how it integrates with my system and my work flow before buying it.
On Android though cant find a free version on google play store and the apps from github page ask me for a license right of the bat.
Is there a freemium version for Android to test the app with limited functionality like in iOS?

If no, any plans for it? And any plans for universal license?

Thank you
