Uses the audio autput to generate sound pulses and then detects theecho on the microphone. The echo signal can be visulised in a map,Fourier transformed or just as the time-series waveform. Great forinvestigating/demonstrating acoustics principles. Free & NoAds.RECORD_AUDIO Permission to use microphone to detect the echo.WRITE_EXTERNAL_STORAGE Permission is so that data can besaved.Features/Specifications:• Sampling frequency 44.1 kHz.•Sampling duration 0.001 s to 5 s.• Single / Continuous modes.• SaveData in CSV files.• Pulse Generation: • Single/Train/Chirp. •Square/Sine waveforms. • Tukey/Hanning Envelopes. • Pulse frequency20 Hz to 22.05 kHz. • Pulse duration up to 1 s.• MAP – Visualisethe echo. Colour or Black and White. Pixel value from RMS orabsolute value. New line for each echo trace. Move device whilstpulse-echoing to generate a map.• Fast Fourier Transform (FFT) of8192 data points to determine frequency content between echo detectlines.• Peak frequency detection• FFT AveragingFor Indication Only.Use Ear Protection if required. Due to the limits of the typicalmicrophone dB range on most devices, distant echo signal are likelyto be too weak to detect clearly unless extra amplification or astrong echo is present.For fun/educational/research use. This isnot ultrasound and NOT suitable for any medical imaging. This appcan create annoying loud sounds, so use ear protection if required.

Function Generator 1.2 APK
Dual channel function / waveform / signal generator for the speaker/ headphone audio output.No Ads, No Permissions, No In AppPurchasing, No Limited Features. Full Version.Output is 16 bit foreach left and right channels and at 44.1kHz. Output will depend onyour device hardware. Some device hardware may may filter out theDC bias and low frequency signals. At high frequencies, thewaveforms will be distorted due to limited number of samples foreach waveform (for example at 4.41kHz, a sine waveform will beapproximated by only 10 points). Therefore this is forfun/educational use, for critical applications use a realcalibrated function generator.Left and Right audio channels can beassigned to either channel 1 or channel 2.Sine, Square &Triangular waveforms.Frequency range from 1 mHz up to 22kHz.Amplitude as percentage 0-100%.Set duty for square waveforms orskew triangular waveforms to get saw waveforms.Offset the phase ofwaveforms.Sweep frequency or amplitude (Single, Repeat & Bouncemodes).Amplitude Modulation (AM).Frequency Modulation (FM).Burstmode for a specific number of waveforms (1-10000).White noise &pink noise Generator. Pink (1/f) noise falls of at ~3dB per octavebetween 43 Hz and 44 kHz. Memory slots to save & recall channelconfiguration.Select values with spring slider or number pad.Moredetailed explanation available on website

(0.1 to 10 BPM/bar)♩ Beats highlighted on musicalstaff as they are played. Accent or mute any of the beats bytapping above/below note.♩ Select up to 12 Beats per bar. Set beatvalue to half note, quarter, eighth or sixteenth. ♩ Three differentsound effects to choose from. ♩ Select from 0 to 9 sub beatdivisions.
Spirit Level 2.01 APK
Spirit Level. No Permissions Required. Free & No Ads. • Bullseye level with roll & pitch gauges screen• Horizontal andvertical bubble level and angle gauge screen. • Calibration featureto correct for accelerometer misalignment & different axissensitivities.For best results touch CAL and calibrate first. TheSpirit Level is only as good as your accelerometer. For indicationonly. Don't damage your tablet or phone, use a real spirit levelwhen appropriate.• Pause button to hold the current reading. • Zeroand reset button to make measuring angles easier. • Option to autoselect screen based on inclination.That's it. Enjoy.
com.keuwl.arduinobluetooth APK
Control your electronic project with an Android device. This appcommunicates using Bluetooth to an HC-06 or HC-05 Bluetooth modulein your project. This app comes with a library containing 11Bluetooth examples for Arduino. It can also be used with RaspberryPi or any other rapid prototyping system in which you have includeda suitable Bluetooth module to your project. Ideal for learningelectronics in a fun way.

Audio Frequency Counter 1.03 APK
Frequency counter based on the microphone input. Counts when theinput rises or falls past a set level and converts into intofrequency or a time period. FOR INDICATION ONLY. Results depend onyour device and its hardware. If you just want to know thefrequency of a sound with harmonics (e.g. mucial instrument), a FFTbased app such as keuwlsofts spectrum analyser or guitar tuner(both free) will be better. This app can provide more accuratefrequency measurement for single frequency input signals. Featuresinclude:Display of triggered event count and frequency or timeperiod.Graph of input signal, 2.5 ms/div up to 640 ms/div.Gate timeof 0.1s, 1s, 10s or 100s.Gain from x1 to x1000.Trigger on rise orfall.AC or DC coupling.Set a noise level so new event is nottriggered until the signal has first passed this level.More detailscan be found on the website.
Wifi Analyser 1.10 APK
Monitor strength of nearby wifi networks. Use to find a goodlocation for your wifi hub. Or use to identify a channel withlittle overlap with neighbouring networks.App has 4 screens:• Gauge– shows the signal strength of the currently connected wifinetwork. Also shows maximum, minimum and average values. Graph withauto-scale & speed options.• Channel – shows how the wifinetworks are spread across the channels and overlap each other. •Graph – shows how the signal strength of all nearby networks varywith time. Auto-scale & speed options. Select which networks todisplay.• List – Contains basic information for all the detectednetworks: name, mac address, frequency, channel, encryption typeand signal strength. For indication only. Ads shown on exiting apponly. If you dislike these ads, there is an option to turn them off(enabled after 6 hours) in the settings menu (top left button).
Guitar Tuner 1.41 APK
Straightforward guitar tuner. Single screen app that starts in autotune mode. Simply run the app, hit a string and start tuning yourguitar. Tune into the orange region for a good results or green forperfection.This app uses your microphone to detect the string beingplayed and indicate if you should tune up or down. Pitch pipefunction also included. The standard EADGBE guitar (not implementedfor very small screen devices) indicates current note being playedor allows fast note selection in manual mode. Tuning range from 30Hz (B0) to 4186Hz (C8), so can also be used to tune other stringedinstruments.
Gauss Meter 1.02 APK
This app uses the magnetic field sensor on your device to measuremagnetic flux density (B) in Gauss or Tesla. FOR INDICATION ONLY.Results depend on your device and its hardware. Your device musthave a Magnetic Field Sensor for this app to function. Featuresinclude: Analogue dial to show current reading.Averaging.Maximumand minimum values.Gauss or Tesla units.4 time constant options. 3Refresh speeds.Graph – Shows the time depedence of the magneticfield.Compass Ferrous metal detector – sound frequency will changewith gauss level.Autoscale or manual (pinch & pan)Y-Axis.Calibrate option – If you have a calibrated gauss meter orknown magnetic source, you can use this option to calibrate themeter. (However app is still for Indication Only).More details canbe found on the website.
