ConvertTiles: Unit Converter app for iPhone and iPad

ConvertTiles is a new take on unit converter apps. A simple app where different groups of converters live on separate tiles. It is easy to change units through a simple picker and the tiles save your last used units. With a pro subscription you can customize your tiles with a custom unit set and custom accent colors. An optional colored line around each tile can help you easily find the one you are looking for. With 20 different groups almost any unit can be converted.

The groups are:
Acceleration
Angle
Area
Concentration Mass
Duration
Electric Charge
Electric Current
Electric Potential Difference
Electric Resistance
Energy
Frequency
Fuel Efficiency
Information Storage
Length
Mass
Power
Pressure
Speed
Temperature
Volume

Please note only 6 groups are unlocked by default. A pro subscription is required to fully unlock all 20.
