Excellent ### 5/5 — Very nice! *2008-08-22* Personally I like the way this one works compared to the other conversion utilities. Elegant. ### 5/5 — Best of breed *2008-08-14* Love it - already used it to cook a chicken and a roast! ### 3/5 — great app if you have great eyesight *2008-08-11* This is a really good app that does everything I need easily. My only complaint is the text size in the input and result fields. Its a little small for people with less than perfect eyesight or if youre working in difficult lighting conditions. The situation is made even worse because the text in these fields is greyed out. ### 5/5 — Great app *2008-08-10* Great little app, well worth the cash ### 3/5 — Screenshot? *2008-08-10* My download looks NOTHING like the screenshot? What's up with that? ### 5/5 — Fantastic app *2008-08-08* I had tried the other conversion apps and found that this one delivered the best results. No fuss interface, simple to use and most importantly it works every time. Well worth the $$ ### 4/5 — great but needs upgrades *2008-08-05* great apps. but like the other guy said you can not get the liter function to convert liters to gallons ### 3/5 — need support! *2008-08-04* I can't get the "liters" to stay in view on the scroll down menu...therefore I can't select it.. ### 5/5 — Finally a USEFUL iPhone app *2008-08-04* This is a great app, allowing you to convert pretty much anything wherever you are. Simple user interface, nothing fancy – but truly utilitarian and fast. Great work! For next version, I'd like to see conversion of clothes sizes. I mean, how often have you been in a shop in another country, trying to figure out your shoe size or what size jeans your kids need? ### 5/5 — Australian friendly *2008-08-04* Very good app that is Australian friendly. It converts centimeters, inches, ounces, grams etc. ## Most critical reviews (10 lowest-rated) ### 1/5 — Currency Problems *2015-08-05* I cannot recommend purchase of this app. I bought this app because I wanted to do on the fly currency conversions with my Apple Watch, and it was recommended highly in a Computerworld article entitled the top 23 Apple Watch apps you should get. However, when I tried it today in China, it was more than 10% off today’s USD-CNY exchange rate. I’m glad I didn’t make any decisions using that exchange rate today. Could have cost me big. With no real support, I had to delete it. ### 1/5 — Conversion *2011-11-08* Doesnt work at all just says waiting for 4 days now , Apple said contact the developer if you use those links there is no help or contact at all just some sort of home page with kids pictures.. DONT WASTE YOUR MONEY ON THIS USLESS APP!! ### 1/5 — Just a few more? *2009-06-20* This is very handy. Would be perfect for me if it could convert from chains, links, roods and perches ### 1/5 — Good app! *2008-08-03* Very good app, does what it promises, and well. Ability to save fave conversions would make it even better. ### 2/5 — Out of Date Currencies *2015-07-15* I would have given a 5-star rating but clicking on the support link took me to a blog, it looks like, not any support for the app. I was going to ask how to update the app's currency rates because they're out of date. I like how much the app has the potential to do, but out of date info and no support.. I give it 2 stars. Plus I paid for this. ### 2/5 — Design flaw... *2009-01-15* The C to F temp conversion keyboard LACKS a negative sign key -- makes it hard to convert anything below zero. Overly complex GUI took the iPod "number wheel" metaphor too far for users' own good. I struggle to understand why this was $5, when others are free. ### 3/5 — Currency conversion is worthless *2018-10-01* The program does not update exchange rates, it appears that conversion feature is years out of date. The program does not have a significant number of prefixes/powers for each unit (i.e. milli centi deci deka kilo etc). It would be nice to select the base unit like “gram” then select the precision. ### 3/5 — Bring back the favourites! *2012-12-11* It's a great app, complete, but since the last update, it is not possible to choose our favourite conversions... Please add the feature back! ### 3/5 — Simple elegance; needs more. *2009-02-07* Lots of these apps in the store. This has one of the most streamlined interfaces and most of the necessary categories. One big omission is currency conversion - without that ability it's not a complete converter for me. Shoe/clothing sizes would also be useful. For all the rest it does a great job. ### 3/5 — It's good but... *2009-01-16* How do I type in the minus symbol for negative temperatures? Don't think it has the option to. ## Most praised reviews (10 highest-rated) ### 5/5 — Very handy *2017-05-04* Very useful everyday conversion app easy to use.. the hidden flatulence engine is a surprise bonus. ### 5/5 — Works great for me *2016-08-20* I love this app. I've had it for over five years now (I think). Had a different one before but preferred this to it. I have to be clear though, I only ever use it for volume, distance, and weight and for these it works fantastically every time. Never crashes or gives me bad information. ### 5/5 — very useful app *2011-02-26* i have had this app since the app store opened, and it has been perfect. is also has a great UI and a clean icon. if you’re like me you’ll make good use of it. (there was one update that had a annoying sound effect but it was later fixed so this means the developers are actually listening) i am however wondering why they are now selling it for $5 (it was $1 for a very long time) — the competition for this type of application is fierce. maybe put it on your watch list for when it goes on sale! :) ### 5/5 — Worth the money *2009-02-11* This app is well worth the money ### 5/5 — Perfect *2008-11-23* For what it is, it's perfect. I use it constantly in cooking, homebrewing and work. Worth the tiny price. ### 5/5 — The way it should be *2008-10-08* And it is! Simple, elegant, easy to use. ### 5/5 — Great, easy converter *2008-09-16* This is a great converter, very easy to use, not full of useless measurements, I've paid for three other converters but this is the only one I've been happy with, I've deleted the others, waisted money, but i would have paid what i waisted on the others for this one, I'll be keeping this one, for sure :-) ### 5/5 — So useful and easy to use *2008-08-28* The new interface is perfect. It's really quick and easy to get results. Great app for the price! ### 5/5 — Très bien *2008-08-27* Simple et efficace ### 5/5 — Great app *2008-08-24* This app is wonderful I have used it so many times well worth the money if you need somthing like this. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
