Yes. There is. Since I've had the same experience as you, i've purchased Chess PGN Master

I liked it so much i got the PRO KEY and the Master's Games. It really is good software
It will play back PGN's, or even analyze them.
Essentially to use it like 'ICHESS' you load the file and put the app in "Guess The Move" mode.
Oh.....whatever halppened to Ichess on Android?? It looks like, from their website, they are only supporting it on the Apple devices.
For years my favorite Android app has been iChess. It will display puzzles from pgn files, even those created by the user. I've accumulated over a dozen files with almost two-thousand puzzles.
Unfortunately after upgrading to Android 11, iChess failed. It closes immediately. I was surprised to discover that iChess is no longer listed on Google Play. Attempts to contact developer have failed.
Does anyone know what happened to iChess ? Is there any similar app that will read user-created pgn files ? I tried many other chess tactics apps, but almost all use built-in files and cannot read pgn files.
