For model rocket enthusiasts who use Chute Release, the latest version of the AltimeterThree app now calculates descent rate before and after Chute Release opens. So now you can measure the rocket’s tumble (or drogue) descent rate, then the final landing speed.
To update your app to the latest version, go into the app store on your phone, and search for “AltimeterThree.” Be sure to enter it as all one word.
