Also, Prime lite, and Prime Pro versions.
Some have reported that these are missing from Google play store.

Unfortunately yes, only the 12C emulator remains. However, with some searching an older version of the 15C emulator, and even cracked versions of the Prime emulatpor, can be found on several sites that do not respect the copyright laws very much. They work fine, also on modern Android versions.

The go1xc apps are excellent but they have issues with modern Android versions and are essentially abandonware. I only could get them running on Android 7 and up by using OneHandOperation from Samsung to emulate the menu button with a gesture, and on Android 10 in portrait mode. As they are abandonware the author would be very kind to make them open source, the changes required to get them running fine again are small.

Touch RPN is a paid app that emulates a 11C for free, and when paid it offers a 11C (ad-free), 15C, 10C or 16C.

For the often forgotten 16C there is an open source solution for Android: JRPN, see https://github.com/zathras/JRPN_Android .

There are further droid48 and derived from it, 48sx, both open source and they don't require a ROM image.

As for non emulators, there is https://play.google.com/store/apps/detai...lk.rpncalc , a mix of HP1x functionality. It shows the entire stack on screen, but is not programmable.
