*2018-11-08, version 3.0.1*

I had the free app on my work phone and it worked great, but after buying it on my personal one now it would just crash. So I uninstalled and reinstalled and now everything seems gtg.

### 5/5 — Airjock

Great app! Precise, easy to use - absolutely nice!

### 5/5 — Awesome app

*2018-10-09, version 3.0.1*

I use this app all the time. Unless I am teaching my students dimensional analysis, I tell my students to get unit converter and that I only use GUnit. Works great and very easy to use.

### 5/5 — Top App!!

*2018-06-29, version 3.0.1*

Excellent great app.

### 5/5 — Love This App!

*2018-06-10, version 3.0.1*

Got the app originally on my iPhone 3GS and still use it regularly to this day.  It’s great, accurate and convenient.  No complaints!

### 5/5 — Always there when I need it

*2018-05-06, version 3.0.1*

Everyone should have this app. I have used it countless times over the last several years. No issues AT ALL. Apple should buy it and make it standard on all iPhones!

### 5/5 — Great app

*2018-04-08, version 3.0.1*

It works perfectly, and has been good for years!

### 5/5 — Like it

*2018-03-29, version 3.0.1*

Tons of conversion apps out there. I like this one. It’s great for any type of measurement or conversion rate you could think of, from currency to physical data like length, area, temperature etc...  The interface is very easy and fluid.

### 5/5 — TOP TIER CONVERTER

*2018-02-06, version 3.0.1*

Outstanding app for all conversions. I have used it for years, have not found anything better or faster. Waiting for the update that will convert my wife into a 23 year beautiful blond.🤦‍♀️

### 5/5 — Just right

*2017-11-13, version 3.0.1*

I’ve been looking for something to replace Apple’s Convert and this seems to be it. Clean simple interface,  no unnecessary bells and whistles. Great little app.

### 5/5 — G-unit

*2017-08-15, version 3.0.1*

Had it for years!  I love it n it helps me all the time!!

### 5/5 — Very useful

*2017-06-28, version 3.0.1*

Use it frequently. Whether in my job as an engineer or outside of work. A great tool, easy to use and quick. Only downside is I used to do many of these conversion calculations in my head. Hate to loose that ability and become a millennial 😊

### 1/5 — Unstable for the last several iOS releases

*2025-12-17, version 3.0.1*

I used to use gUnit regularly. As of the last few iOS releases, it will run fine for several launches, then crash each time after that. I have to delete and re-download the app in order to use it again. I’ve found another solution and have now deleted this app.

### 1/5 — Il n y a pas tout

*2012-05-08*

Je suis dégoûté j acheté cette App pour pouvoir convertir des nok norvégiens et pour les devises il n y a presque rien

### 1/5 — Currency flop

*2012-05-08, version 2.0*

There are only a few currencies.  If you only need to know US$ to AUS$ to pound to Euro, then by all means get it. If you travel elsewhere then don't waste your money, it won't do Ringet, Baht, S$, Dong or anything else you would need in S.E. Asia.  There is nothing for Asia period save yen and HK$!!!

A total flop and waste of my money unless they upgrade it quick.  This APP will go to my last page with other stuff to be erased if I need storage space.  Too bad, with all the travel I do I had already made a space for it on my front page.

### 1/5 — Annoyed

*2010-09-05, version 0*

downloaded specifically to convert gallons to litres during a touring holiday in France. This ap has no mention that the gallons used are US gallons - quite different to English gallons. It cost me a lot of money as costs were shared based on different vehicles mpg. The competition clearly state that they are US gallons - PLEASE BE AWARE THE USA IS NOT THE WHOLE WORLD.

### 2/5 — Currency converter is dismal!

*2022-09-13, version 3.0.1*

There is no Peso converter. The one function I need the most. Also the app has not been updated in a long time. They are referring to iOS 8

### 2/5 — Incomplete

*2011-05-17*

Only good for americans who don't need volumes converted.  No imperial units. U.S.  ounces cups pints quarts and gallons are all less.  So no good in Canada or England and any Commonwealth nation.

### 2/5 — Centlitre

*2010-04-28*

Il manque des unités dont les centilitres dans les volumes !

### 3/5 — Great app but no imperial measurement on US Imperial

*2019-01-26, version 3.0.1*

This is a great app, but in canada and the rest of the world that use imperial measurements these are different to US imperial Measurements.

### 3/5 — Imperial please

*2011-01-21*

This app has been out for over a year now and still no imperial measurement!

### 3/5 — Needs more conversions

*2009-11-12, version 0*

Liked the interface, but it needs more conversions to be helpful to me at work. I'm an engineer, and having a comprehensive table of conversions, including force and angular velocity, inertias, etc would be a real productivity tool. Hopefully updates will fix this. My favorite converter is multiconvert, but this app has a better interface for quick conversions.

### 5/5 — A lifetime partner

*2026-03-26, version 3.0.1*

I’ve been using this app for 10+ years. It has been extremely helpful in both random events and everyday situations.

### 5/5 — Excellente application

*2025-09-05, version 3.0.1*

Très facile de l’utiliser, très grande diversité d’unités de mesure à travers lesquelles on peut faire nos choix, conversions instantanées, excellente application. Félicitation et merci de répondre à ce besoin d’utilité courante.

### 5/5 — The best

*2025-07-15, version 3.0.1*

Years ago I checked many converter apps and most were not accurate, this app was the most accurate at its conversions! Very impressed with it!!

### 5/5 — Bring it back!

*2024-09-26, version 3.0.1*

This is the most useful app on my phone and I am SO glad I found it before it was taken down from the app store. BRING. IT. BACK.

### 5/5 — gUnit

*2024-07-17, version 3.0.1*

This converter is the best one you can buy for your iPhone.

### 5/5 — Superbe

*2023-02-27*

Très pratique ce convertisseur d’unités et indispensable pour les voyages. Bravo.

### 5/5 — Conversion Extraordinaire!

*2022-11-24, version 3.0.1*

This has simply been my “Go-to” app for any comparative information required. Had it now for almost 10yrs and through several phones, and is always on front homepage. Simple, and easy to navigate. Two 👍🏼👍🏼 thumbs-up from me.

### 5/5 — My GoTo conversion app for many years

*2022-05-18, version 3.0.1*

It simply works and is very simple to boot which is why I gave it 5 stars. It is simply amazingly no how often I use this gem of an app. I highly recommend this to anyone.

### 5/5 — My Favorite Utility App

*2021-06-29, version 3.0.1*

This is my favorite app among my utility apps.  I use it all the time!  I use it especially in the kitchen and when I’m building some structure outdoors.  Love it, it has almost everything you need.

### 5/5 — It measures up!

*2021-03-07, version 3.0.1*

This app has has been essential for scientific, culinarily, and practical measures such as converting liters per 100 kilometers to miles per gallon. I like the challenge of mental math in my old age and this app “measures up” beyond my expectations. However, it does not convert length, velocity , and time relative to the speed of light (e.g., 8 light minutes to the sun).
