Field notes
The proposed recorder combines phone motion sensors with a flight model selected for the aircraft being flown, including separate constraints for powered aircraft, sailplanes, engine-out flight, and free-flight classes. It is designed to estimate during the flight and then smooth the complete track after landing, with planned IGC and KML export. The page emphasizes local storage and explicitly rules out use as a certified navigation instrument or emergency aid.
