Unit & currency Converter (ver 1.2) manual

Hello. I'm android boy, a chief of developing team of Smart Tools co.,

There are already a lot of Unit Converter apps on Google Play. But most are inconvenient and difficult to use because of poor and complicated UI (user interface).

In fall 2013, I released Unit converter app that had most intuitive and simple UI. In spring 2014, I added currency feature. This feature requires internet permission to refresh exchange rates.

※ Introduction video



※ Supported unit sections
 ① Basic : length (distance), area, weight (mass), volume (capacity)
 ② Living : exchange rate, temperature, time, speed
 ③ Science : pressure, force, work (energy), power, torque, flow, density, viscosity
 ④ Misc. : angle, data, fuel consumption, cooking, illuminance, astronomy, radiation, prefix, binary


※ How to use
 1) Select a category (Basic / Living / Science / Misc.)
 2) Select one of 4 groups.
 3) Select one unit by LONGCLICK on the list or tap the selector.
 4) Input the number with a keypad.




※ Currencies (exchange rates)
 - 99+ currencies of 125+ countries.
 - [My currency] is set automatically according to your phone carrier and language.
 - You can select My region(Europe, America) & Major currencies in the list on the action bar.
 - It is limited version. If you want to select other region/currency, you must change [My currency] at the settings. The pro version supports all currencies without any action.

 - The refresh icon takes the latest exchange rates from our servers.
 - The exchange rates are based on Back of canadaFx-exchange RSS, etc.
 - The rates are for information purposes only.


※ Favorites
You can choose 4 favorites in Science and Misc. categories.


※ Landscape mode
If your device is a tablet PC or a phone with high-resolution (at least 960x540), this app supports landscape mode.
Go menu -> landscape.


※ How to input fractions
Length and weight unit groups have [. /] button on the keypad. You can input fractions.
 1 2/3 =>  [1] + [./] + [2] + [./] + [3],
 1/4 => [./] + [1] + [./] + [4]
 2 lbs 6 oz => [2] + [./] + [6] + [./] + [16] pounds 


※ How to input "deg min sec"
Select "deg min sec" or "deg" unit. You can input them with [.˚'] button on the keypad.
1˚ 23' 45.67" =>  [1] + [.˚'] + [2][3] + [.˚'] + [4][5] + [.˚'] + [6][7]
0˚ 1' 2" =>  [.˚'] + [1] + [.˚'] + [2]


※ Data storage/flow ?
This app shows both data storage and data flow in data section to save a tab. Similarly, it shows speed and running face units in speed section.


※ FAQ
A. How can I convert from gram to litre?
Q. Gram is weight unit, Litre is a volume unit. They cannot be converted. volume x density = weight. Water 1g = 1ml Gasoline 1g = ~0.7ml

A. I guess that weight is different from mass.
Q. Yes. Weight = Mass x Gravity. Gravity in earth = 1 (not 9.8 m2/s). Weight is same to mass in Earth.


※ Pro version additional features:
  1) Ad-free
  2) Message box for unit name and formula
  3) Full currencies(99+) and Full regions.
