With this app, you can analyze data from physics experiments on your smartphone, without the need of a desktop computer. Currently, reading data from the phone's internal sensors as well as manually adding data is supported. In the future, support for an external logger will be added, using an Arduino-compatible board to sense voltage, current, distance, and more.
HOW TO USE:
Swipe from the left to reveal a list, which includes "sources" and "outputs".
Under the "sources" category, you can add data sources. These can be any of the following:
- Manual: always with the same value, which can be later changed in the table
- Sensors: read values from an internal phone sensor
- Functions: apply mathematical functions to another source. Simply enter the source name between quotes and it will be recognized in the expression.
Under the "outputs" category, you can visualize the data either in a graph or a table containing all the recorded values.
To begin data collection, simply tap on the play button at the top right corner. Collection frequency and timeout, as well as an option for manual collection, can be modified by tapping on the stopwatch icon on the app bar. Data collected can then be exported by tapping on the export button next to the stopwatch or analyzed using the app.
Data analysis:
This can be performed in the "graphs" view. Each graph allows for data trimming (leaving only visible points), as well as function fitting.
The ability to perform functions as well as analyzing collected data sets this app apart from other ones available in the Play Store, allowing the user to perform a physics experiment by use of a smartphone only.
