About

Nello

Features
Read full description

Nello is a calm, strengths-based autism behavior tracker for parents of autistic kids — and for autistic teens and adults tracking themselves. Log meltdowns as ABC data (antecedent, behavior, consequence), sensory moments, sleep, food and wins in a tap or two, see the patterns behind the hard days, and hand the BCBA or IEP team an FBA-ready ABC data report instead of a notebook. The family keeps one record; the teacher adds the school day from a link, no app or account. Works offline. Decode the hard days, celebrate the good ones — without the deficit framing. WHY FAMILIES CHOOSE NELLO • Honest billing — the free tier is useful forever, no card needed to explore, and Nello+ cancels anytime in the App Store. • Works offline, opens instantly — local-first, no account, no forced logins. • A self-tracking mode for autistic teens and adults, not just a parent tool. • Neurodiversity-affirming — rainbow-infinity, never a puzzle piece.
