Annotate Audio vs Nora

Teach your iPhone to recognise any sound. Then let it listen for you, recording only when that sound happens. Annotate Audio learns the sounds you care about: your dog barking, a snore, a cough, a baby crying, a doorbell. Leave it listening overnight or while you're out, and come back to clips of exactly what you asked for, sorted into folders. No hours of silence to scroll through. HOW IT WORKS 1. Pick a sound. Each sound gets its own folder. Add a "Not …" folder too, so it learns the difference. 2. Record some reps. Every recording is a rep. Five reps of two sounds is enough to start. 3. Tap Train. Your model is built right on your iPhone in a few minutes. No cloud, no code. 4. Turn on auto record. It listens and saves a clip every time it hears your sound. NEVER MISS THE START Auto record keeps a short rolling buffer, so every clip begins before the sound did. Manual recordings can include the 2 seconds before you tapped record, too. A DOG THAT LEARNS WITH YOU Your pixel pup levels up as you record: Puppy, Learning, Good dog, Top dog. It earns a collar at 5 reps, a tag at 50 and a crown at 100, and tells you what it still needs before it can train.
