Nello Downloads & RevenueNello: Autism Behavior Tracker · Google Play

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.
