Behavior Observation Ledger

Behavior Observation Ledger helps educators and behavior-support professionals collect observation data quickly and review descriptive patterns without another monthly subscription.

Included: ABC events, frequency and rate, duration, latency, partial interval, whole interval, momentary time sampling, time scatterplots, pattern review, session comparison, printable summaries, JSON backup, CSV export, and a local-first buyer app.

Pattern summaries are descriptive. The software does not determine behavioral function or replace a professional functional assessment. It is not a diagnostic, medical, legal, district-compliance, or intervention-recommendation system.

One-time purchase: US$29. No subscription. No account required. No cloud database is required for the core app.
