### 5/5 — This best of its kind!

*2026-03-14*

I love the customization, that it stores your last input and units used, and that it lists the results in every unit displayed. I previously used an app called QVert Pro which has more or less the same features, but I needed to find a replacement since I’m unable to download it on my new phone, and then I found this. I have another paid app from the same developer I often rely on so I feel this one is also well worth the purchase!

### 3/5 — Had been using

*2025-06-04*

When I discovered today that this app is not updating, it’s calculations daily made me wonder if they’re right. 
Some of the calculations need to be updated like currency every day if it is not going to be, then I’m going to quit using this app.

### 5/5 — Everybody needs this app

*2024-02-02*

I left a review a while ago and just wanted to add that that I’m still using this app and am so satisfied with it. I’m not an engineer or scientist and I use it constantly. And if I was I would really appreciate it. It’s probably my most used utility. This is the first time I have ever left a second review for anything.

### 5/5 — A must have app

*2022-04-15*

Use it daily. Ideal while watching TV or reading the news. Excellent to convert metric, currency, and  distance  values. Use it on iPhone and iPad.

### 5/5 — It's used way more than I thought It would be

*2022-02-27, version 3.8*

I have used this app so many times in the last three months it's crazy. I had no idea how much I needed it until I got it - and it's super easy to use. And the currency conversions include probably every currency, including Bitcoin.

### 5/5 — Simple and Comprehensive

*2020-11-12*

This app calculates everything easily. Pick the main category, put in the number you want to convert, and the app immediately provides your answer plus the answers for every subcategory in that main category.   Elegant and easy

### 3/5 — Euro default currency

*2019-11-06, version 3.8*

Maybe I’m not seeing how to change Euro as default currency? If you want to convert USD to MD Peso, that is not an option. Very limiting otherwise very robust.

### 5/5 — Daily Work

*2019-08-19*

This app is indispensable. I use it every day. Thank you.

### 5/5 — Good app

*2017-11-14*

Update:  I've now been using this app for a long time and it is excellent. I like the changes recently introduced in V3.0

I like this app. It's worth taking the time to customizing it to your personal needs. There's a lot to it.

### 5/5 — Only the best

*2017-07-03*

Converter Pro is as good as it gets. There are a huge number of categories and selections to choose from. Plus you can customize it to put the items you most frequently use on top for quick access. Without a doubt, this is a must have app.
