### 3/5 — Conversions MAY be inaccurate

*2021-11-28*

I only found this to be the case in one instance, thus far, but just be on the lookout. While converting 1010 to hexadecimal the app said it was “five,” when I very well know it to be “A” aka “ten.”

### 5/5 — Just updated to iOS 14

*2020-09-22*

This app is great, but I just updated to iOS 14 and I cannot get into the menu to activate my purchase.

### 2/5 — Unfortunate.

*2020-06-12*

This app seemed to have every function I was looking for however in its current form it is completely useless on iPhone 11. The “result” part of the UI is completely cut off the screen! There is a small ad just above the keypad. No problem for a free app. Unfortunately I paid for the “pro” version hoping that removing the ad would cause the UI to pull together so it would all fit on my screen. No luck! To make matters worse, the app still displays the ads even after the IAP.

### 5/5 — Design is so cool

*2019-11-27*

Design and colors are really great 👍🏻 Thanks for useful tool

### 5/5 — Very good app

*2015-09-01*

Personally, I prefer bits with 0&1, but color is fine. Everything else works perfect!

### 5/5 — Review

*2015-07-28*
