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.

Includes an option to calc the required pinion by simply entering the desired head speed.
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
So you will need an active GPS connection for the app work.

You can use this app with bike smartphone holder and anything else.
It shows you total distance(mileage), current distance, max and current speed.
Kilometers(km/h) as well as miles(mph) are supported 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.
* permission.WRITE_INTERNAL_STORAGE is used for some Samsung-devices, because their LED is managed by writing data on the internal storage.
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.

- Millisecond precision LED flashing
- Flashing to the beat of music
- Pattern flashing
- Audio tachometer mode
- Torch/flashlight mode
- Burst mode
- 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.

Frequent blinking flashlight may make you an epileptic seizure so that if you find yourself starting to feel bad, then turn off the application.
The theme visualizes the battery charge level as tachometer/speedometer in the Smart Battery Monitor (SBM) or the SBM Widget. The icon in the status bar indicates the level with segments of a circle. Additionally, the level is shown in percent in the center of the circle. Looks best on high-resolution displays (e.g. Samsung Galaxy S, Motorola Defy, HTC Desire, ...).
IMPORTANT: This is a theme for the Smart Battery Monitor and the SBM Widget. You must have the free Smart Battery Monitor app or the SBM Widget to use this theme. After installation, it can be selected in the settings menu or you can choose the theme if you add the SBM Widget to your desktop.

RPAS Logger Lite (Drone / UAV) is an essential tool for all Remotely Piloted Aircraft Systems as it incorporates a Remote Pilot Logbook, RPA Logbook (UAV Logbook / Drone Logbook) and Battery Logbook & Battery Management solution all in one. Remotely Piloted Aircraft (RPA) is the official name for the commonly used terms such as Drone, UAV, Quadcopter, Multicopter, Hexacopter etc.
You can download the user manual for the software from our website. http://rpaslogger.com/rpas-logger-lite/
RPAS Logger Lite is built to support all companies and pilots flying a Remotely Piloted Aircraft (RPA) as a hobby or for commercial activities to establish a safety culture and also record the information required to maintain government compliance.
In Australia (The RPAS Logger can be used worldwide) it is legal to fly a RPA / UAV for commercial activity as long as the ‘pilot’ has a UAV Controller Certificate and is operating under a company with an UAV Operator Certificate. With RPAS Logger the official record keeping has just become much easier.
* Full pre and post flight logging of individual cell voltages for LIPO and other battery types
* When charging your battery you can log your pre and post individual cell voltages and internal resistance for each cell.
* For each RPA (UAV / Drone) you fly you can configure a checklists for pre-flight, post-flight and maintenance for each Remotely Piloted Aircraft. You can define checklists for all types of RPA like DJI Phantom, S800, S1000, AR.Drone / Parrot Drone etc
* Configurable checklists for pre-flight and post-flight checks for each Accessory for all or a particular RPA. This can include Gimbals, GPS units, FPV camera etc
* In-Flight timer with low battery, very low battery and critical battery alarms that can be configured for each battery mAh associated with each UAV. This will give you an audible alarm at each configured time while you are flying.
*Reporting functions for batteries, pilots and RPA.
* A Barcode scanner for fast battery, RPA and accessory access. (Instead of typing in or selecting an item you can just scan the barcode with your phone camera and it will pre-fill the details saved against that barcode)
All data logged through this app will be compatible with other versions of RPAS Logger, up to our Enterprise software that includes risk management, safety management, inventory, customers, jobs etc.
Pre-configured checklists can be downloaded from our website.
Full documentation is available from our website
RPAS Training and Solutions Pty Ltd is Australia's largest provider of RPA / UAV Training and professional RPAS / UAS services for the civilian market to comply with the Civil Aviation Safety Authority (CASA) regulations. (CASA is the FAA equivalent of Australia)
RPAS Logger users use their UAV Controller Certificates and UAV Operator Certificates to conduct RPA activities which include Aerial Photography, Powerline Inspections, Real Estate Photography, Mine Surveying etc
