### 1/5 — Bad app

*2025-11-13*

So many pop up adds it’s unusable. Put a banner ad at the bottom or something. Makes it completely useless

### 4/5 — Wish ad-free version were available

*2025-08-04*

App works fine, but the ads get in the way with popups and are very distracting. 

It’d be worth a pro version without ads.

### 4/5 — Can’t Handle Radix Point in Hex Mode

*2025-06-19*

Can’t Handle Radix Point in Hex Mode

### 5/5 — Useful and Non-Intrusive

*2025-02-28*

I was thrilled to find a converter for hex and decimal formats that does not collect data. Thank you for making this and sharing it for free!

### 4/5 — Good

*2023-08-10*

How about add big/little endian switcher?

### 4/5 — Almost Perfect

*2022-07-10*

Works great for 99% of what I use it for. It is missing ability to calculate subnet when borrowing bits from the host bits and the IP entered as 192.168.1.0/27 doesn’t seem to work mask is set to 255.255.255.238 and gives 2 hosts per subnet. Should be 8 subnets with 30 hosts and mask is 255.255.255.0. 

It would also be great to have the ability for the systems to calculate the number of subnets sometimes. 

But it’s still a fantastic free tool. 

Many many thanks for this.

### 4/5 — :)

*2020-06-15*

It’s cool but doesn’t convert numbers with a decimal point like converting 1101.01 to base 10
