## Most critical reviews (2 lowest-rated)

### 1/5 — Was five stars until you got rid of portrait mode

*2020-01-23, version 3.0*

What a dumb decision. The calculator itself is shaped to be held in a portrait mode. Forcing it to be in landscape mode just makes it too small to be properly usable.

### 5/5 — Really nice !

*2015-09-04, version 1.0*

This is a great emulator and recreates the feeling of using the original.  Lots of enhanced features.
