Converts from metric to imperial using fractions and decimals. No garish and irritating ads.. so far. Everything you want with nothing you don't. ### 5/5 — Very decent converter *2021-01-31, version 4.1.2* You’ll like it ### 5/5 — Great App! But, I’d love a widget *2021-01-09, version 4.1.2* I love this app, it is far better than anything else out there. Yet, I would love to have a home screen widget for quick access, as well as defined currency conversions. ### 5/5 — ONLY APP YOU NEED FOR NUMBERS *2020-11-29, version 4.1.2* This app is AMAZING!!! Not only can you convert the units we are all used to (inches to centimeters, litres to gallons, the American dollar to Swiss Francs, etc), but this even has units that boggle the mind! Find out how many raindrops it would take to equal the size of the Great Pyramid! AMAZING APP! GREAT USER FRIENDLY INTERFACE! 5+ STARS ALL THE WAY!!! ### 5/5 — is just the best *2020-11-07, version 4.1.2* to convert anything to anything, this app is amazingly great for that, specially with currencies. the interface is amazing and beautiful. easy to use, up to date. ### 5/5 — Best converter app! *2020-09-21, version 4.1.2* Would be nice to see this app get some love with iOS/iPadOS 14 release features. Great app! ### 5/5 — Excellent *2020-06-12, version 4.1.2* Very easy to operate. You get your answer pretty fast. I like it a lot. ### 5/5 — Insightful *2020-04-26, version 4.1.2* Interesting app ... ### 5/5 — Very nice *2020-04-26, version 4.1.2* This app is great... very very useful ### 5/5 — Excellent *2019-11-25, version 4.1.2* Great app to work ### 5/5 — Mr *2019-06-13, version 4.1.2* So simple for an ole bloke ### 3/5 — Good app, bad UI. *2019-05-25, version 4.1.2* I had this app a couple years ago and it was great. Easy to navigate and very useful. Just redownloaded it and the new user interface is atrocious. Everything is %100 harder to use. It’s confusing and annoying. The calculations are correct and it can still be useful, I just wish it was more user friendly. ### 5/5 — Fantastic *2019-04-21, version 4.1.2* It does everything it is advertised to do, with no ads and no interruptions. A simple, intuitive interface makes it quick and easy for any conversion. ### 5/5 — 정말 최고임 *2019-03-26, version 4.1.2* 나라별 단위까지 다있음 평도 단위에 있고 디자인 깔끔하고 정말 맘에듭니다 ### 5/5 — Language *2019-03-23, version 4.1.2* Please add the arabic language ### 5/5 — A great app *2019-03-06, version 4.1.2* I don’t use this app often but when l need it,it gets me answers immediately. The best conversion app around. ### 4/5 — Beautiful and fun *2019-02-28, version 4.1.2* It's a hoot to compare non-standard units. Can we define our own, for example the current weight of a particular baby? I'm doubtful about accuracy, though, when I see a gold bar described as 398.6692575ozt instead of 400 Troy oz. ### 5/5 — Love it! *2018-09-07, version 4.1.1* Great interface and reliability. 5 Stars!! ### 5/5 — Great finally a converter with fractions of an inch!! *2018-08-29, version 4.0.3* Very nice converter, well laid out, easy to use. Gives you many different conversions at the same time. The best feature and most other don’t have is fractions of an inch!! As well as feet and inches shown together. Great for construction industry. Highly recommended. ## Most critical reviews (10 lowest-rated) ### 1/5 — Whaaaaa?!? *2018-07-22, version 4.0.3* 1.37 kPa should NOT equal 137 mmH2O! It SHOULD equal 139.701141549 mmH2O. Am I missing something? Conversions are not a fluid concept! ### 1/5 — Cumbersome *2017-03-03, version 4.0.3* Title says it all. ### 1/5 — Too complicated *2015-07-20, version 3.2* This app tries to be all things to all men (and women!) It fails on all counts. If you want to convert Hedgehogs to Mallard ducks then this is your app! If you're a simple bugger like me, and just want to convert pounds to kilos, feet to metres etc. then Google is your friend! ### 1/5 — Current version - broken *2015-04-19, version 3.0.1* This app used to work wonderfully. But now there is no text, just the color background. Will update rating once this is fixed. ### 1/5 — Wrong Conversion *2015-03-02, version 3.0.1* I like the format. But, the conversion from milliliters to teaspoons is totally wrong. And I was looking to this for a package label. Now I can't trust other numbers. ### 1/5 — No text *2015-01-31, version 3.0* Was a great app. With latest update, though, all text has disappeared, leaving it completely unusable. Please fix this. ### 1/5 — Still Doesn't work *2015-01-26, version 3.0* Even after this update it's still completely broken on iOS 8 (iPhone 6). All the buttons are blank. You can tap things but there is no text anywhere. ### 1/5 — Just got worse *2014-09-17, version 2.3.2* I think it's bull that you no longer support iOS version 1.6.x you have lost my support and the only way to get it back is to start supporting iOS version 1.6.x and adding LTC and VTC, only then will I consider giving a better rating ### 1/5 — Won't open! WTF *2014-07-11, version 2.3.2* Downloaded! So… where is it? Go back to app, says OPEN....????? Nothing!! ### 1/5 — Height? *2014-07-02, version 2.3.2* Where is height converter meters to foot? ## Most praised reviews (10 highest-rated) ### 5/5 — Convertible is back! *2026-05-20, version 4.1.2* It's been too long! ### 5/5 — My go to for over a decade *2026-02-03, version 4.1.2* Even though this app isn’t maintained any longer and even disappeared from the App Store for some years, I’ve found various methods to transfer the app to all of my phones over the years because I use it so often. Been useful traveling to over 40 countries! ### 5/5 — this is very good tool *2025-12-11, version 4.1.2* Better than the paid ones! ### 5/5 — Still the best *2025-12-08, version 4.1.2* Simply the best converter out there. The design is excellent. Clean and easy to use. ### 5/5 — I like using this *2023-02-05, version 4.1.2* Really like the layout. Easy to find the units I am looking for and makes it quick to use ### 5/5 — Must Have *2022-10-13, version 4.1.2* easy, free and adless! No premium or ad removal iap! no account necessary! customizability! available on basically every iPhone! (i love it when i can find and app compatible with my 6) Although it takes a minute a two to figure out how it works, its always a handy little tool to have that you want at unexpected times. Absolute must have. I feel a unit converter should be inter grated into ios already, but this is the next best thing!! thanks developers!! ### 5/5 — Not updated *2022-07-29, version 4.1.2* But it doesn’t need updating because it’s already the best out there. Which other app can tell you that 1 baseball bat is equal to 16 AA batteries? Or 1 white pointer shark is equal to 21.65 bananas? ### 5/5 — Excellent app *2022-02-07, version 4.1.2* Simple, easy to use, versatile, no ads, all one could ever request. ### 5/5 — Donkey to Pirate-Ninja conversion - 5 stars *2021-08-27, version 4.1.2* What an awesome app :) ### 5/5 — The best! *2021-04-08, version 4.1.2* I have tried many unit converter apps but this one is the best. It’s so cool looking and easy to use. I just want to congratulate the developer! Well done! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
