The Updated version of Prime is ready for download.
Previous versions of !ObservePrime are NOT compatible with iOS 8. We strongly suggest making use of the DropBox storage option to secure your data for future updates.

!Observe Prime is an intuitive and flexible behavioral observation tool. It can be used to track a single behavior or class of behaviors.

!Observe is not only a simple interface to record observation data, but much more. It will automatically calculate RPM, Average Duration, Percentages, and more. Did I mention that it will create charts and tables for all your data as well?

You want your data in a report? No Problem! Export all tables, charts, and graphs using the DropBox option. From there, you can send to yourself, colleagues, parents, or whomever you choose.

Also, all your data can be seamlessly shared and accessed from any computer (Mac/Windows) or device using the Dropbox option.

Whether you are a teacher, a school psychologist, a behavioral psychologist, or anyone who routinely undertakes formal behavioral observations, !Observe is a tool that will make your life easier.

Comparison Peer: Option to enable peer samples on per session basis. Simple setup, no fiddling. Simply turn the feature on and it will automatically devote 20% of the observation to peer data collection in 30 second intervals.

Session data tables now display average peer data side by side with client data on a per client behavior basis.
