About this app

Are you tired of having poor measuring instruments in physics lessons? Then this is the right thing for you!
VidAnalysis is a multipurpose tool: In this app measurement, physics and the actual math behind it are combined. For example you can film the free fall of a small ball or a pendulum experiment with the camera of your smartphone or tablet. Next you analyze the video by marking the object you want the motion to be tracked in every frame of the video. With this information the app creates a time-x-distance-, time-y-distance-, x-distance-y-distance-diagram and adds all values to a list. You can also add your own function to the measured values into the diagrams.
Isn't that cool?

Summarized: With this app you can
- organize your videos for analysis
- choose measuring points for analysis
- set an absolute length as reference to reality
- set an coordinate system and even rotate it
- correct your chosen points in analysis
- display three diagrams, where you can add an function as a model
- display the list of all measured values
- share and save this list as CSV file

Ratings and reviews

I wanted to use this app to capture video of a scale in an elevator. So I just needed the video in very small resolution time steps. But when trying to advance, it gets stuck on the same image, and sometimes exits ungracefully.

The frame by frame time stamp is great for timing objects in the lab (high school science). The rest of the features I haven't gotten to work yet.

Controls for moving through the video frame by frame don't work, and marks on the screen to set position either disappear or can't be reset.
