I'm sorry that currency exchange rates feature was removed because of the lack of internet permission.

※ How to input fractions
In length and weight sections, this app has [. /] button on the keypad. You can input fractions with it.

ex1) 5 1/4 =>  [5] + [./] + [1] + [./] + [4]
ex2) 3/8 = 0 3/8 => [./] + [3] + [./] + [8]   (Look out!! 3/8 is less than 1.)
       or [3] + [./] [./] + [8]


※ How to input "ft and inch" at the same time
Select "ft in" unit. For various inputs, you can use fractions. "lb oz" are the same.

ex1) 2' 3.5" =>  [2] + [ ' "/ ] + [3] + [ ' "/ ] + [5]

ex2) 0˚ 1' 2" =>  [.˚'] + [1] + [.˚'] + [2]


※ Data storage / flow ?
The app shows data storage and data flow in data section so as to save a tab. It is not a mistake. Similarly, it shows speed and running face units in speed section, too. By the way, do you know the difference of "kb", "kB", "kib", "kiB", "kbps"?
 b : bit
 B : byte
 k : kilo (1000)
 Ki : kibi (1024)
 M : mega (1000 x 1000)
 Mi : mebi  (1024 x 1024)
 kbps : kilo bit per second


※ Landscape mode
It supports landscape mode for tablet PCs. Select more menu (3 dots) at the top-right corner.


 FAQ
Q. How to copy the number to clipboard?
A. Double-tap on the number (since v2.4.2)

Q. How can I convert from gram to litre?
A. "gram" is weight unit, "litre" is volume unit. They cannot be converted. 1L of water = 1kg, 1L of gasoline = ~0.70kg

Q. Where is "A(amp)" unit?
A. Click the favorite icon (star) in Science category. Select [Current] checkbox.

Q. "kg" is not weight unit, but mass unit.
A. I know. weight = mass x Gravity. "mass" and "weight" are same in earth.
Above all, "weight" is a friendly word and the public do not understand "mass" perfectly.

Smart Speed (v1.5) manual

Hi. I'm Android Boy, the chief developer of Smart Tools co,.

Smart Speed (Speed Gun) can measure the speed of a moving object by touching screen. There were several speed apps in the market, that are designed only for baseball and hockey speed. This app is not a toy, but one of tools.


※ Introduction video



※ How to use
 1) To measure speed, input the shortest distance to a target.
 2) Touch your screen following the target.


※ What is the shortest distance?
"The Shortest Distance" is a minimum distance between you and a road. You must measure it before using the app. An actual ruler and Google Maps can be a good solution. Otherwise, how about using my rangefinder apps?
  1) Smart Distance  go Blog
     https://play.google.com/store/apps/details?id=kr.sira.distance
  2) Smart Measure  go Blog
     https://play.google.com/store/apps/details?id=kr.sira.measure


※ Menu & Settings


※ How to calibrate it
If the measured speed is faster or slower than actual speed, you can calibrate it with [Speed Calibration] at the settings. 25-400% is a selectable range.
In other words, when the app shows 50km/h even if actual speed is 75km/h, set the calibrateion to 150%.


※ Pro version additional features:
 1) No ads
 2) Smart Distance is integrated
Get it on Google Play


 What's new
 - v1.5.0 : Android OS 10 support
 - v1.4.1 : Galaxy S7 support
 - v1.4 : Material design
 - v1.3 : Action bar
 - v1.2 : 10 languages support
 - v1.0 : Smart Speed released (Mar, 2011)
