### 1/5 — Confusing

*2026-03-16, version 1.8*

Can’t change from volume to distance or anything. Stuck on volume conversions.

### 3/5 — Great, but…

*2025-10-12, version 1.7.3*

An excellent app, sadly captured by the in-your-face imperative of relentless and difficult to delete advertising. I’ll find another one that doesn’t try to sell me stuff I don’t need, and just does what I need.

### 5/5 — Very User Friendly

*2025-09-20, version 1.7.2*

This is a great conversation app.  You can access the measurements you want by side swiping and then create a list of  favorites (your preferred conversions ) for future use by tapping the + 
 icon. So happy I got this.

### 1/5 — Take your  ads and shove it

*2025-07-13, version 1.7.2*

Adds you can’t pause or skip on a unit converter no freaking thank you

### 5/5 — More useful than I ever thought use it all the time and it is teaching me how to convert from metric

*2025-05-17, version 1.7.2*

Great app

### 1/5 — False description

*2025-03-23, version 1.7.2*

This app lists “in app purchases “ but promptly takes $10.99 from Apple when you download it!!  Talk about false advertising!!

### 5/5 — Professor

*2025-03-18, version 1.7.2*

Very applicable

### 5/5 — Ability to Add and Cheap for the paid version

*2024-09-15, version 1.7.0*

Love the unit conversion and the ability to do simple math while converting at the same time. Only app I found that can do this seamlessly. Very affordable and love the features!

### 5/5 — Miles & kilometers?

*2024-09-14, version 1.7.0*

It’s a great app except when it comes to length it doesn’t allow miles in kilometers. What’s that about? It ruins the entire app otherwise I would give it a Ford easy

### 1/5 — Was good, now totally crippled by ads

*2024-08-19, version 1.6.9*

I can’t even change the units any more. Uninstalling and moving on
