5 Best Android Oscilloscope App

1. Oscilloscope

Download the App on the Google Store by clicking this Button
“Features
•  Scope, Meter, & FFT displays
•  FFT peak tracking with readout
•  Quickly take screenshots
•  High contrast colors for view-ability

Permissions
This app requires minimal permissions, but must have permission to access and record audio from the device’s microphone, as well as permission to write screenshots to the device’s storage.”

2. Oscilloscope Pro

Download the App on the Google Store by clicking this Button
“NOW FREE : I thank everyone for the support along the way. Now everyone can enjoy this application for free!

NFX Oscilloscope is a simple signal vs. amplitude analyser.

Currently there are two input options for the application.

***** USB SUPPORT ****** (only for android 3.1 and greater)
PLEASE ENSURE THE GABOTRONICS DEVICE IS UP TO DATE!!
The newest and best input option is a USB hardware device provided by Gabotronics. USB host mode has now been compatible since android 3.1, therefore most new phones and tablets will support USB host mode (Please check device). NFX Oscilloscope supports the Gabotronics Xprotolab/Xminilab, this has 2 analogue input channels and 8 digital channels and measures a tiny 2.5 x 4 cm!! The device it’s self is a cheap portable alternative to most mainstream oscilloscopes, and has many different features. Connecting the Xprotolab to the NFX Oscilloscope provides a powerful and cheap oscilloscope platform for your portable needs. For more information on the Xprotolab or Xminilab click the following links.
http://www.gabotronics.com/development-boards/xmega-xprotolab.htm
http://www.gabotronics.com/development-boards/xmega-xminilab.htm

So match this application with the cheap device from gabotronics and you will get a great portable oscilloscope!
Note: Only the analogue channels, logic Channels and tone generator is supported on the xprotolab/xminilab/xprotolab plain

Spec list for xprotolab:
2 Analog Inputs
Maximum Sampling rate: 2MSPS
Analog Bandwidth: 200kHz
Resolution: 8bits
Input Impedance: 1MΩ
Buffer size per channel: 256
Input Voltage Range: -14V to +20V

Currently the USB mode has been tested on Samsung Galaxy Nexus , Asus Transformer , Asus Nexus 7 , Samsung Galaxy S3
There has been problems reported with android version 4.3 and USB host, there is a major bug in the release, which is set to be updated at some point in the future.

Please note : Most devices will need a OTG cable to enable usb host mode. See phone specific instructions for more information.

***** Microphone SUPPORT ******
The second option is the microphone input to the android device. This can be used to attach a scope lead to the jack socket. More information can be found at the following website.
http://www.instructables.com/id/A-Preamplifier-for-Smartphone-Oscilloscopes/
Features include, triggering for different impulse and continuous signals. In addition to this there is level measurement and fundamental frequency readings

It is possible to control the amplitude, time/div and trigger level whilst monitoring. Settings included trigger directions, sample rates and voltage span calibration.

Have a look at this blog for more scope cable information from a fellow user of Nfx oscilloscope.

3. Sound Oscilloscope

Download the App on the Google Store by clicking this Button
“This program turns your device into a simple oscilloscope function of the spectrum analyzer, signal source is the microphone input of your device. With this program you will be able to compare the level of noise (sound) in different areas or from different sources, as well as to determine the spectrum of audio signals. You can take a picture signal by moving the program mode pause and examine in greater detail the form and spectrum of individual sections of the signal.
The spectrum of the signal is determined using FFT.”

4. AR-Oscilloscope

Download the App on the Google Store by clicking this Button
“Android Bluetooth Oscilloscope.
It can be used on any mobile device with Android, Windows or Linux PC (Mac is coming) system using Bluetooth technology. It means that there are no any wire connections to your phone, tablet or PC, which can guarantee the safety of your mobile device or PC, plus portability.
The oscilloscope is the most frequently used, most flexible device for electric measurements.
It visualizes an electric potential over time function, producing much more information than other potential and current measurement methods.
With an oscilloscope the following quantities can be either directly or indirectly measured:
direct voltage, alternating voltage, direct current, alternating current, time, time delay, phase, phase difference, frequency to view live waveforms, make measurements.

For more info visit http://ar-oscilloscope.com

Features

Demo mode available.
Displaying the audio waveform captured from a microphone.
Accelerometer waveform, x y z.
Measure: frequency, min/max, peak-peak
FFT for microphone input.
Shows trigger level information
Save screen captures from your instrument onto your mobile device
Save signal to file in csv format.
Protocol Decoders:
– SPI
– I2C
– Guess bitrate
– UART
– 1-Wire link layer
– IR NEC

Math channels

System can display up to 5 math channels.
• Main operations: +, –, ×, /, sqrt, x^y, exp, ln, log, abs
• Trigonometric functions: sin, cos, tan, asin, acos, atan
• Additional operands: PI, T (time)
Math example: exp(-T*125)*sin(2*pi*1000*T)

Control the following functions

• start/stop/single acquisition
• change time/div
• change volts/div
• turn channels on/off
• select trigger type/level
• screen zooming
• full screen mode
• font size
• signal retention level
• double click on triggers sets them to zero level

5. SmartScope Oscilloscope

Download the App on the Google Store by clicking this Button
“!!! Now also supports audio jack input !!!
.. but working so much better with a real SmartScope attached 🙂

Combined with the LabNation SmartScope, this app turns your tablet into a mobile oscilloscope/waveform generator.

Howto’s available on our youtube channel

Check the SmartScope tech specs at https://www.lab-nation.com/specs

This app will ask for the following priviledges:
– USB access: for detecting the SmartScope
– Access to your filesystem: for saving waveform data
– Network access: for uploading saved waveform data, and for detecting a SmartScope on the local network
– Microphone access: for audio jack input
( – Dropbox access: only when you want to upload your waveform data to your dropbox account)

NOTE: If you cannot install this app, it probably means your device doesn’t support USB on-the-go. This means you can’t use the SmartScope. If you’d like to try the app still, you can download the android package (APK) from our website at https://www.lab-nation.com/app”
