At a recent launch I had great success with the Featherweight tracker system. I used it on 4 flights by mounting it in a 54mm nosecone that I just moved between rockets. However one issue I ran into involved using the iOS screen recording capability. I added the Screen Recording button to my control center so I could easily start recording my screen before a launch so I would be able to replay the launch later. However during the first couple of flights the recording ended well before the flight did. I finally realized that my screen was going to sleep due to the Auto-Lock setting in the Display and Brightness settings category. I had it set to auto-lock the screen after just 1 minute. So unless I touched the display to keep it awake it would go to sleep and end the recording. You can set it to 5 minutes or to Never so you don't miss out on recording your flight. Just remember to set it back to a shorter time or it will be hard on your battery. I feel the ease of use of the system and its accuracy allowed me to fly more (and higher flights) than I did when I used a RDF type tracker.
