Behavior Observer
Data analysis for IEPs & FBAs
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
Easily collect classroom behavior data and turn it into clean reports for IEP or FBA meetings. BOSS (on task), time sampling, frequency, duration, and ABC observations.
Behavior Observer makes data collection and analysis easy, with multiple observation types and organization for your caseload. Designed by a practicing school psychologist, this app knows the most important features and customizations that professionals need.
Built for school psychologists, BCBAs, RBTs, behavior specialists, and special education staff. Generate instant reports to help with IEPs, FBAs, and clinical decisions.
FIVE OBSERVATION METHODS, ONE APP
Frequency — tap to record behavior counts
Duration — time the length of multiple behaviors at once
Time Sampling — momentary, partial-interval, whole-interval, and full BOSS (on task) scoring with peer comparison
ABC — capture Antecedent/Behavior/Consequence to analyze behavior triggers and functions
Latency — measure the time between a prompt and the student's response
APPLE WATCH ENHANCEMENTS
A silent wrist-buzz alerts you to interval timers. Tally frequency counts, run duration timers, repeat data entries, and capture latency right from the watch, synced live with your iPhone. Collect meaningful data without an obvious phone or clipboard in hand.
CLINICALLY USEFUL DATA
Drill down to the most essential behavior data needed to help your team make decisions (including peer comparisons and comprehensive reports capturing behavior patterns and functions).

Ratings & Reviews

What's New in 1.1
New
- Resume unfinished sessions. If the app closes mid-session, nothing is lost. Sessions save every 10 seconds, and you can pick up where you left off from Sessions.
- Edit saved sessions. Change the observer, the session note, or whether the peer was observed. Swipe to delete an observer note.
- Duration: Option for "Peer not observed this session." Peer percentages include only sessions where the peer was observed.
- Apple Watch now works with watchOS 10 and later.
Better printed reports
- US Letter pages that break cleanly between sections.
- Page numbers and a footer on every page.
- Key numbers at the top of each report.
- Rate by Setting on the Frequency report.
- Print All can include your session notes.
Charts and numbers
- Trend lines drop to zero when a behavior stops.
- By Session shows every session, and date labels no longer overlap.
- Results across several sessions now pool all intervals and minutes, so a short session counts less than a long one. Partial and Whole Interval peer % uses only the intervals where the peer was coded. Some totals from earlier sessions may differ slightly from past printouts.
Recording
- Fixes across Frequency, Time Sampling, Duration, ABC and Latency, including undo, custom settings, and pausing.
- Backups keep recent, daily and weekly copies, and the files are smaller.
