New Circular Motion experiment, in both methods. With the camera, film a marker going round from straight above: Accelab fits the circle and gives you the marker's x, y and angle against time, with the radius. With the sensors, lay your iPhone flat on a turntable: Accelab records its angular velocity and its centripetal and tangential acceleration, with ω² in the export, ready to plot a against ω².

Choose the experiment first, then the method. Each method's tile shows the graph you will plot and the columns of data you get.

Export by graph: choose the graph you want and Accelab exports just its two columns, ready to paste into Desmos. All Data and a custom choice of columns are still there.

Past Runs lists each run by its experiment, with the method and date underneath.

New Projectile experiment in the Camera method: film an object in flight and Accelab gives you its x and y position against time, measured from where it started.

Level your iPhone: before you film a projectile, Accelab uses the iPhone's sensors to help you set it level, and the recording screen shows whether it still is.

Tracking now tells you when it loses the cart or the object, so you can track again from that frame or mark the rest by hand.

Past Runs shows what each camera run filmed: Air Track or Projectile.
