## Most critical reviews (8 lowest-rated)

### 1/5 — Rubbish anyway

*2021-12-12*

Full of trackers and data stealers. Don’t trust this

### 1/5 — Limited hex conversion

*2021-05-25*

The application gives an error if the hex number goes above 4 digits. That may be fine for beginners, but it is not good enough for use on an advanced or professional level. 

I do really like the three number always being shown (decimal, hex, binary)

**Developer response:** Hi,

If you change to Binary mode, you can change the overflow to 8 hexadecimal digits by clicking on the "32-bit" button. We default to 4 digits this because showing 8 hexadecimal digits by default shows a lot of lines in the binary display.

### 1/5 — The fastest I have ever deleted an app

*2021-01-05*

This is a fail.

I went to covert a 6 digit hex number into decimal and received an overflow error after 4 hex digits. 

I’d like to think that someone will still find this useful but I’m struggling to think who that might be.

### 4/5 — Want a version without ads

*2021-03-04*

I love this app so much; I’m an embedded firmware engineer and this makes my life a lot easier. The only reason I gave 4 stars was I wish I could pay for a version without the ad at the top.

### 5/5 — Irritating ad’s, Difficult to ise

*2021-12-13*

How about providing a paid version with no ad’s and some sort of help since the UI is so “different”?  Deleted from my phone for just these reasons

### 5/5 — 10+

*2019-04-16*

this application is the best, it has all the most important functions and works perfectly

### 5/5 — Exactly what I needed!

*2018-06-05*

Works perfectly!

### 5/5 — Very useful and well coded app

*2016-05-12*

Works great! Would recommend
