## Most critical reviews (5 lowest-rated)

### 4/5 — Extraordinary

*2020-09-03, version 1.0.4*

Really very practical.  Only my language (Spanish) is missing.  Something like this would also be extraordinary for the Amstrad Firmware :-)

### 5/5 — Excellent app but wish it supported iOS 9

*2022-07-31*

IOS 9 support would be nice

### 5/5 — Great app for quick referencing

*2019-08-26*

This app is incredibly useful for whenever you need an in-depth explanation of the workings of practically any Z80 instruction. The interface is simple, with an easy search function and an alphabetical list. The explanations are clear and concise, and the example code is a useful touch.

### 5/5 — Very handy

*2019-08-07*

Very cool. But the ‘prev’ is obscured when in portrait layout, and there is no explanation of the colour coding that I can see. But even so it’s a handy tool when developing Z80 assembly.

### 5/5 — Top Referenz, dafür das es kostenlos ist

*2019-02-23, version 1.0.2*
