Publisher: Tapbots–Price: $1.99–Convertbot is an intuitive converter app that works with just about every unit, all in a simple easy-to-do interface. Now when I say every unit, I mean every unit: over 440 different units are supported, including computer storage size, days and hours, and force. Though looking simple, the app proves very versatile. For example, the app updates its currency info upon each launch, provided you have an internet connection. Overall, I really liked Convertbot’s stability, and its stylish user interface, which you can check out in the screenshots below. I would definitely recommend this application to a friend, and it gets a rare perfect 10 out of 10 from me. Thumbs up.
