### 4/5 — Great App

*2022-07-16*

Please add a reverse mode. i.e. recalled digits must be entered in reverse.

### 5/5 — Beautiful app

*2019-12-21*

Nice music, great functionality. Wish there was an option to replace the recall time count-down with a loading bar or remove altogether, also wish it went higher than 20 digits in sandbox mode. Presumably caps here as well in test mode. But awesome app!
