### 5/5 — Thank you!

*2023-09-23*

So many of the “top apps” for unit converter are ugly, have ads and want ridiculous amounts for ad-free (sometimes with subscriptions). I’m glad this is free but the tip is well deserved for a clean and useful converter app!

### 5/5 — Please add Afghan currency too

### 5/5 — Great app!

*2023-03-19*

This is an awesome app Steven! Thanks for making it!

### 1/5 — Useless

*2023-01-19, version 1.8*

Decided to try this app to get away from the bulky app I usually use, but found out that it doesn't even include my country's currency. One of the strongest in the world. 🤣 Yeah, I'm not paying monthly for this scam. Two stars for effort with other conversions though.

### 5/5 — A simple, no frills converter

*2023-01-09, version 1.8*

This is a very clean, well developed app that gets the job done.

### 5/5 — Lots of power

*2022-11-01, version 1.8*

I am new to owning an iPhone. So, under the phone app tool, I searched for calculator, degrees, measurements and one other variable. The results were pretty good. This particular app was the second on the list. I was impressed with the advertising. Nice features, if they work… thinking that to myself. After an easy install, did some testing under certain conditions; have to say, impressive indeed. I appreciate a good clean, easy using, rock solid application. For myself, I will use this and turn it on to my friends. They are professionals engineers, such as myself.

### 5/5 — Great tool

*2022-10-23, version 1.8*

Having spent the last 20 years as a developer I’m not easily impressed, especially with software. This application is  simple, clean, intuitive and functions as advertised. On top of the afore mentioned this is free, no ads and no tracking! I can’t say enough good about this application. THANK YOU!!!

***I tried 4 other “top rated”apps and immediately deleted them - messy forms, clunky and bombarded with ads and beg screens.***

### 5/5 — Best Converter Yet

*2022-10-08, version 1.8*

As CTO of Blue Planet Research, converting values are a daily exercise. This is one of the cleanest simple interfaces of any calculator/converter that I have seen. 

Thanks Steven!
