I’ve had this on my iPhone for a few years. It’s a great tool. My only complaint would be a couple times I’ve found I wanted a certain unit of measurement that isn’t on the app. One example is “Minutes per Mile”. Runners use it rather than mph. Otherwise it has worked flawlessly. Thanks

So far I’ve only used this app on my iPad Pro and think it’s great. At first I thought it was going to be a dud because I couldn’t find “length” as a choice but then I realized the developer used “distance” instead. Not the terminology I was expecting but that’s really a nit. I see another reviewer asked for a “six plus” screen so apparently there’s some issue with the way this displays on the iPhone 6+. Since that’s what I have I hope I don’t have to come back & lower my rating once I use the app there. Until then, I highly recommend this app.

Now many times when I put in a number, the converted unit doesn’t make sense. For example: under Mass or Force/Weight I enter 95 kilograms. The resulting conversion to pounds is 2.09E+02.Smaller numbers convert just fine (up to 45 kg in this instance). This doesn’t happen when converting pounds to kg.

Its so easy to use. I found myself using it often. I believe everyone should have this on their phone. I had to re-download it when it was removed when updating my phone 😮
