### 1/5 — Doesn’t work anymore

*2025-09-27*

Used to work great but is now obsolete. I had another private calculator years ago and the same thing happened. The developer doesn’t keep up with software updates, lets the app become obsolete and discontinues support no doubt hoping you’ll pay for a new one.

### 1/5 — Videos no longer play

*2025-09-24, version 4.0*

It used to be a good app but for over a year it doesn’t play any videos. I think they should update the code because I have the paid version
