Since version 1.7, the package app includes a unit converter.
But currency exchange feature is removed because of the internet permission.

I got a Samsung Galaxy S5.

Hello. I'm Androidboy.


Yesterday I received a SGS 5 phone. The appearance is same to SGS4. Several biometrics features are added. If you had SGS3-4 or Nexus 4-5, there is no need to buy it.

Anyway I'll do my best to calibrate my apps on it.

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 Bank of canadaFx-exchangeFxexchangeRate, 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]

※ 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 1L = 1kg, Gasoline 1L = ~0.7kg

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.

I got a Nexus 7 2nd-gen tablet.

Hello. I'm Androidboy.

Yesterday I got a Nexus 7 2nd-gen tablet.
Because both Nexus 7(2012) and Nexus 7(2013) had the same device model number, it made me crazy. I had to fix optimization of Nexus 7.



I had calibrated my tools on it carefully. I'll update the apps one by one.

A. No, pure gold and silver are classified as Non-ferrous that has no magnetic field.

Q. It does not react to coins (bottle caps).
A. They are made of zinc, copper and aluminum.



*******************************
  Sound Meter
*******************************
Q. It says "Unable to open microphone.".
A. The other app occupied your microphone. Just reboot your device.

Q. Why does it stop at 82 dB? Is it a bug?
A. It is normal. The microphones were aligned to human voice (300-3400Hz, 40-60db) by the phone-makers, and the values of sound pressure stop at 32767.(32767=2^15-1). So the louder sound cannot be recognized. SGS3(81-84db), SGS2(98db), HTC Desire HD(80db), Galaxy Note(91db)... Please use it as an auxiliary tool.

Q. It does not work on my phone.
A. This app receives SPL(sound pressure level) from your phone. Because some phones do not support this method, it does not work on GT-I9001, Xperia(X10mini, X8), LG(LG-P500, LG-P350), ZTE, Huawei, NEC etc.

Q. Where is the Screenshot and CSV file (saved in the Pro version)?
A. /sdcard/smart-tools/, /storage/sdcard0/smart-tools/, /mnt/sdcard/smart-tools/, /storage/emulated/0/smart-tools/.

Q. How to calibrate it?
A. In a very quiet room, the measured value should be 25-35dB. Go menu > calibrate.

Q. I could hear nothing. But it points out 30-40dB.
A. The microphone can catch very low-frequency noise. 0 dB means vaccum (no air).

Q. Are the results dBA weighted?
A. Yes, it had been calibrated by a real SPL meter with dBA. But, because the measured value is not perfect, dBA means nothing.



*******************************
  Vibrometer
*******************************
Q. How to calibrate it?

I got a Nexus 7 (2012).

Hello. I'm Androidboy, the chief developer of Smart Tools suite.

Nexus 7 was not released in Asia.
Today I got it with the help from an US friend. (-:


Essentially, several tools require a rear camera.
(distance, protractor3, compass, flashlight...)

Because Nexus 7 has no rear camera,
Smart Tools package app did not support Nexus 7 yet.
If I support Nexus 7 forcibly, other Nexus7 users will have complaints.

Now I decided to support Nexus 7 in the next version(ver1.5).
I'll show this message in several unsupported tools. "Sorry. there is No camera."

If you already purchased my app and Nexus7 is your secondary device,
this news will be good. Otherwise I do not recommend purchasing it.

Have a Smart day~
Thank you.

Smart Tools review (by Eric Wrye)

Hello.
Recently, I found that my best user, Eric Wrye, reviewed my app in his YouTube channel.

Because he explained almost menus and settings (so it takes 24 minutes),
if you want to use Smart Tools package fully, this video will be a good guide.

Are you ready? Click the play button.
