### 5/5 — Decent

*2022-03-05*

It’s not too bad but it’s a bit confusing

### 2/5 — UI issues but could be great app

*2020-10-30*

On all screen that require keyboard entry the app fails to operate and the keyboard never goes away which makes it unusable

### 1/5 — Crashes

*2020-09-13*

App closes when I try to utilize the decrypt! Bummed out

### 5/5 — Nice, versatile, no problems

*2018-10-27*

I use ciphers with students when we do escape room like activities. I keep looking for a robust but simple app to help speed up the process. I really appreciate the simplicity for both the Caesar and Vigenere Ciphers. The Enigma is nice too but definitely requires some prior knowledge and experience to work. I haven’t played with the Mod Calculator. Would like to know if there is an Android version I could recommend to others.

### 1/5 — Would use if it worked

*2018-10-02*

Same as the previous review. Won’t go past the load screen

### 1/5 — Yep, it just crashes.

*2018-10-01*

A dual code wheel splash screen comes up, then the app crashes - reliably.
 This one’s got to go.

### 1/5 — Crashes

*2018-05-17*

Crashes when you open the app. Too bad.
