Nello: Autism Behavior Tracker

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.

HOME AND SCHOOL IN ONE RECORD

The aide logs the lunchroom meltdown as ABC from their phone, with where, how intense and how long, and it is in your record before pickup. At the IEP meeting the ABC data report covers both: the Monday-morning cluster, the fire-drill antecedent, the headphones that helped.

PRIVACY, PLAINLY

No account. Your record stays on your phone unless you share it with family, and nothing about you or your child is sold or shared.
