It is THE reason I tried this app & I have not been disappointed. They have everything I could ever want - and then some. It is very user friendly. I am very happy. And to the developer…thanks for respecting our privacy. I always want to support developers & companies that respect customers privacy, so thanks! ### 5/5 — Very handy!! *2021-11-30, version 4.4* Easy to use and helpful. Wouldn’t want to be without this! 👍👍 ### 5/5 — Handy app *2021-10-22, version 4.4* This is a very handy app when you need to find equivalence for cooking, gardening,etc ### 5/5 — Excellent converter *2021-10-20, version 4.4* I have been using the Trelleborg Converter for several years now and it is truly excellent, free to use if you don’t mind ads but probably worth upgrading if it is being used commercially and well worth £4.99 ### 5/5 — Top App to have at hand! *2021-08-31, version 4.4* Had this App for ages and always find it does the job brilliantly! Well done and so refreshing you’re not continually bombarded with in app purchases!!!!! ### 5/5 — Convertir *2021-08-01, version 4.4* Was dreading changing my beloved old converter but had to as old was obsolete, cracked on with this one immediately with no issues, so easy & straightforward to use, very happy with this one. ### 5/5 — Retired Engineer *2021-07-22, version 4.4* I like the wide variety of units and ease of use. ### 5/5 — Extremely useful *2021-06-29, version 4.4* I initially got this app for use when traveling, and now I find myself using it surprisingly often at home. Love it! ### 5/5 — Amazing *2021-03-10, version 4.4* This is, hands down, the best unit converter I have ever used. ### 5/5 — Accurate & Friendly *2021-02-01, version 4.4* It is an excellent app. I like because it is fast and easy. ### 5/5 — Very useful *2021-01-07, version 4.4* This is probably the most frequently used app on my phone outside of essential type app’s like banking, email, etc. Such a handy tool. Brings peace between the metrics and the imperials. Long live the metrics! ### 5/5 — By far the BEST converter. *2020-12-30, version 4.4* All in One! You will be surprised by the amount of data you can convert. Being trying many different converters and this one is by far the best one ever. NO ADDS, NO hidden FEES. ### 5/5 — Great app *2020-12-30, version 4.4* Really useful tool with all the conversations you’d ever need plus some you’ll never use (probably) Also has a built in calculator 😊 ### 5/5 — The best I’ve found *2020-11-25, version 4.4* Don’t let the strange name put you off, this is a great application. Far and away the easiest conversion app to use that I’ve found and also the most comprehensive. What a treasure! ### 5/5 — The best *2020-11-20, version 4.4* Simply its awesome, and can say nothing but great. ### 5/5 — Master Converter *2020-09-27, version 4.4* The best app ever. Thanks developer. ### 5/5 — The best *2020-09-11, version 4.4* One of the best apps I have downloaded Always in use ## Most critical reviews (10 lowest-rated) ### 1/5 — Inaccurate currency conversions *2015-03-20, version 3.1* This might be ok for technical conversions that don't change but its currency conversions seem to be years out of date. ### 1/5 — Converter Errors *2015-03-13, version 3.1* Pointed out error with volume conversion 4 months ago, 1 update later no correction made. Error in converting UK gallon to cups, otherwise I think this is a fine app ### 2/5 — Use it frequently *2014-09-05, version 3.0* New version is awful. Un pleasing to the eye and not as user-friendly. The previous version was far easier to use and much nicer to look at. Shame, it was an excellent app and I enjoyed using it. ### 2/5 — Good BUT *2013-06-22, version 2.1* after paying to get the full version with shoe size conversion, I discovered there are no Australian size options! Not good!?!?! And by the way Australian women sizes not = UK!!! Currency should consider displaying more than two for comparing! ### 3/5 — Fading Stars *2025-09-04, version 4.9* Loved this app and it’s free. Lost 2 stars, however. The currency converter still updates but conversion to US dollars no longer works. ### 3/5 — Wrong Currency rates *2015-03-12, version 3.1* The latest update still has a ton of wrong rates. The app itself is excellent can ask for more, but I can use it because the results it gives are wrong. ### 3/5 — Currency list is not that thorough as it can be *2014-05-04, version 2.5* I wish more currencies could have been listed in the conversion list. ### 3/5 — Converter app *2012-10-03, version 1.4.2* Awesome app, so handy! I use it all the time. Would be handy if it could remember your most commonly used conversions, or at least didn't default to the same conversion every time you opened the app. Nonetheless very handy! ### 3/5 — Good *2012-08-18, version 1.4.2* The app is alright, but it's dumb how you have to pay to get more features. I also didn't like the fact that you have to scroll through everything to find what you want. ### 4/5 — Great app apart from one annoying thing *2025-08-14, version 4.9* I use the app mainly for currency conversions but has many other calculators which I use from time to time. The only thing I’d like changed is to have favourites selected by default when the app is launched. It’s a pain to have to select the favourites star every time the app Is launched. Will update review to 5-stars when that feature is added. ## Most praised reviews (10 highest-rated) ### 5/5 — On Point *2025-11-11, version 4.9* App has always performed as needed with accurate information. ### 5/5 — Excellent App! *2025-08-14, version 4.9* I love this App. It is so usefull and easy to manage. ### 5/5 — Great for converting *2025-01-17, version 4.8* This app works great for converting anything that I’ve needed to convert so far in every day life. This app would’ve even been helpful in college when I was taking my engineering classes. ### 5/5 — Wow!! Awesome app - many tools in ONE place *2024-12-01, version 4.8* I am thoroughly impressed with all that is available in this one app! Now I can get rid of the other 5 apps for travel because this has it all. I wish the timezone reflected both 12H and 24H. That would be too cool. ### 5/5 — Taxi *2023-02-23, version 4.7* Great app. Hi conrad ### 5/5 — Great tool *2023-02-14, version 4.7* From day-to-day conversions on site, to the occasional obscure unit I’d forgotten even existed, the app has them all. Favourites make sure the most used are easily accessible while the obscure are easy to locate in the functional interface. ### 5/5 — Incomparable *2022-11-06, version 4.7* L'ultime convertisseur. ### 5/5 — This is the one 👍 *2022-06-26, version 4.6* After Vert was discontinued I’ve been looking for another conversion app. Simple and to the point. Works great! ### 5/5 — Simple, Functional and Accurate. *2022-06-04, version 4.6* I try to get my chemistry students use this. How can it be better? ### 5/5 — Currency *2022-03-24, version 4.6* I really like this app. Just a suggestion: when I am using it to know the current value of a dollar against foreign currency, it would be so much better if USA is a the top of the long list of countries. I don’t like to scroll down, almost to the bottom, every time. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
