Through the calculation frequency, the sound is analyzed to determine the revolutions of an engine.
It is necessary to indicate the characteristics of the engine prior to reading.
May not work on all engines. It works worst with engines with the exhaust sound very muted and mechanical noise engines (air cooled engines).
It is normal to show some value even if no motor function.
Keywords: rpm, acoustic tachometer, sound, tach, rpm gauge, revolution counter, rev counter, rc, fft, tachometer
Please use it for measuring the rotational speed of the motor, such as drivable model car.
It has featured focus for noise removal.
It has featured speed conversion panel.
It has featured memo panel.
It is also offering nice skins.
* Please measure in a state of only motor sound, for example remove the gear.
* Please measure as close to the motor microphone.
The sound of the blades will be analyzed and the according headspeed will be calculated.
Using Settings you can choose between standard (rpm up to 4000) and micro sized (rpm up to 8000) helicopter and setup the number of blades between 2 and 5.
Before starting the measuring you have to set an estimated headspeed. You can expect most accurate measurings if set inside the range of +/- 500rpm to your real headspeed.
Works with electric and nitro helis without changing any settings.
For best results please follow these instructions:
Make sure you have not too much side noise like strong wind.
After setting an estimated headspeed place your phone on the ground 1-2m from your helicopter.
Press the "Measure Head Speed" button and walk to a save distance.
Spool up the helicopter to your desired headspeed and wait about 20 seconds.
After the blades have come to a stop retrieve your phone and press the "Stop Measuring" button.
Now you can read the headspeeds during the measuring.
You can save the result to the log history using the menu option. If you enable the option "Save Log Automatically" logs will be saved automatically after finishing measuring.
Touch a log entry in the log history to view saved results. Long touch a log entry to send the entry or delete it.
Use log menu to send complete log history.
We want to increase accuracy and compatibility of this App. So please help us and send feeback to email@example.com
Please supply information about the phone and helicopters you measured the headspeed.
If you have any problems measuring correct headspeed please contact us at firstname.lastname@example.org
We will give you instruction about how to enable debug mode. This mode will write data to your SD card which can help us find a solution.

• The main function
And measurement of the rotational speed
• How to use
· Tap the "Start"
· Turn the motor
· Approach the motor to the microphone
· Rotational speed is measured
· Noise is large, it may not be recognized well
Will be easier to (5 or 10 times the average) recognition When you change the "Boundary value setting", but becomes easier if mistaken.
The application is very easy to use - the smartphone screen is displayed speedometer with a special font that with the right size and quality is reflected in the windscreen. In addition, you can track the speed chart in the history of time saved automatically include data on the maximum and average speed, trip distance and the date of measurement.
NOTE: Read values can be difficult when the application is running in full sun.

- Adjustable duty cycle
- Flashing with screen off
The newest feature in this app is its ability to flash to the beat of music. This is great for parties because strobe lights make music more fun!
The primary feature of this app though is its extremely accurate stroboscope ability. Uses include everything from checking the RPM of your car engine, to calibrating a record turntable, and even to finding the speed of a spinning fan. With millisecond accuracy and adjustable duty cycle, spinning objects can be made to appear stationary.
The LED will continue to flash even if you quit the app, this makes it perfect for use when you need to be visible at night. Mount your phone on your bike or carry it with you walking so that cars will be able to see you clearly.
The new audio tachometer feature allows your phone to listen to a repeating sound and discover the fundamental frequency plus any harmonics. Then with a simple button press, you can flash the LED at that frequency and watch everything freeze.
Finally, the new pattern section allows you to flash your LED in any pattern you desire. With saving and importing, highly complex patterns can be programmed.
Give it a try! There's something for everyone. Whether you're a technical person or a partygoer, this is the strobe light app you want.
A quick note about different phone hardware: This app works flawlessly on some phones and pitifully on others. Before you say "this app is crap" send me an email and I'll see if I can get it working on your phone.
* permission.WRITE_INTERNAL_STORAGE is used for some Samsung-devices, because their LED is managed by writing data on the internal storage.
So you will need an active GPS connection for the app work.
You can use this app with bike smartphone holder and anything else, especially HUD with your car.
HUD means Head Up Display.
It shows you total distance, trip meter, max and current speed.
Kilometers(km/h), miles(mph) and Nautical mile(kts,knots,kn) are supporeted in this app.
NOTE: Due to phone GPS limitation, It may not work well in cloudy weather or indoor places.
And I don't guarantee that it shows accurate data because of GPS errors.
* GPS Map with kmz support (2500+ flighing fields)
* QR Code scanning. Simply scan your battery after each flight and loadcylce an you get a perfect log.
* excel and picture export of all statistics and events
* statistics like motorpower / battery ri / flights per week / consumption / normalized ri to compare diffrent sizes of batteries
* Share find the best RC-Airfields all over the World. No matter if you fly helis,planes,gliders,boats or cars
* speed optimized data entry
* model pictures support
* simple flightbook view (if you do not want to log batteries at all)
* automatic foldable groups for a better overview.
* much more and absolutly free..
enjoy RcLog - the end of lipo chaos ;)
