Field notes
The app supports plot visits that can be linked over time, with stems shifted together onto satellite imagery when phone GPS was off. Its listed records extend beyond trunk diameter to seedlings, damage, competition, crown base, leaf samples, and increment-core details. The publisher says the app works on-device without an account; uploaded plots can be private, link-only, or public.
