Just installed and tested it... read on Bottom line: NO ADS. Simple to use and pretty accurate. It is a pleasure and a nice surprise to find an app like this in the Play Store. And you will not be asked to accept any of those annoying and questionable permissions required by other apps to work (with the only exception of in-app purchases, in case you want to upgrade to the developer's premium version).
Great, but time fractions would be better in time than decimal Great app, but it would be nice if conversions involving time were in time units rather than decimal. E.g 8 minutes/mile gives 4.97 minutes/km. 4m58s/km would be more useful. Maybe there's a setting I've missed...
Good It's absurd, in a good way, how many conversions are available on this app. Coupled with the low permissions, if you ever need anything like this there is no reason not to install it. My opinion, but I have a great respect for free apps that have low permissions.
Clears favorites every time it updates. Great app but I lose my favorites every time there's an update. Annoying.
Perfect Has everything you need in terms of converting values and is virtually ad free.. I say virtually because from what I've noticed they are not intrusive or obstructive ever.
This is a great app. It is simple to use but covers conversions from basic like money, speed, or distance to more complex operations. It is easily customizable with a nice favorites list for your most common conversions. Nice interface, lots of good features, fast and accurate. It is my favorite converter.
