None, app is totally free without ads
Every now and then a new app pops on the Play Store that doesn’t introduce anything new. Instead it makes the apps currently doing the same thing look bad. One of them is S Converter, a unit converter app that is really simple to use and looks good. What else could you ask for?
Don’t let the name fool you, it’s not one of the Samsung’s bloatware apps you’ll hate. It’s an app you simply must like, either for its design (HOLO everywhere) or its functionality. Making a better unit converter app would be really hard after this one.
Upon launching it, you’ll see the Area conversion and the area units below. There is translucent notification bar (on devices running Android KitKat), but still no transport navigation buttons.
All you have to do to convert a unit, is tap on the unit you want to convert from and enter an amount or value. All the other units will instantly be converted, while you type. Lovely
There is a small “bug” if you click on one unit and then on another before entering amount, the first one will stay blank and the other one will contain zero. Not something big, but bug is a bug.
The app features all the common units you’d expect in such app. A plus is currency, which many unit converters don’t have.
– Digital Storage
– Numeral Systems
– Volumetric Flow
The currency conversion works fine, although there are “only” 20 currencies, and you can’t add them on your own. Hope the dev implements it, so that I don’t have to use separate currency conversion application.
The date and time in the action is shown in US format, which should get fixed. The format should be automatically chosen depending on your language, date and time settings. You can refresh the rates by pulling from top, but there is no animation shown during the process. You’ll only get small notification telling you that the rates have been updated.
As mentioned earlier, the app is simply beautiful. There are a few things I’d like to see changed.
First there colors are repeating (each color twice). I can understand the author following Google’s guidelines for HOLO colors, but he could have used similar colors, or just a gradient of them.
All the units are located in the sidebar. And that works well. I would prefer if all the unit names were colorized (as they are in action bar), the sidebar wouldn’t look as boring. That’s only design-wise, the functionality is just fine.
The developer included a dark version in the settings. I prefer the white one, perhaps since I don’t use a phone with amoled display.
The other thing in settings you can change is decimal and grouping separator, as well as showing and hiding units you don’t need. Pretty neat.
Tablet User Experience
The app wasn’t designed for tablets. The developer did a fine job by developing for all screen sizes, but that’s about it. There is no change of user interface on tablets compared to smartphones. At least two columns would be good in portrait.
The review is based on our own experience and devices. Your experience might be different depending upon device you are using and your expectations.
Keep in mind that when calculating the average, ratings don't have the same weight. Performance and design is valued more than regular updates for example.

Super easy to get used to. The functionality is great, and the app completely follows Google's design guidelines.
App isn't developed for tablets, even though it scales well. Navigation bar should be transparent on KitKat powered devices.
