Intervals is a tool for use by special education teachers, therapists and applied behavior analysts to perform ABA interval recordings and time samplings.
Features include ...
* Easy to perform WHOLE or PARTIAL Interval Recordings
* Easy to perform TIME SAMPLING, including MINIMAL VARIABLE INTERVALS
* Perform multiple simultaneous recordings.
* View your results directly on the device.
* Export your results in the industry standard CSV format to view in your favorite spreadsheet.
* Export your results to any popular file sharing service, including iCloud Drive.
Calculations of canceled recordings will not be calculated based on the number of intervals for which results have been recorded instead of using the full number of intervals as if the recording had run to completion.
Fixed issue on startup affecting some users.
Reworked the order of items that display on the Observe tab.
Fixed occasional lockup in adding a new recording.
Fixed several issues with the triggering of notifications.
Improved notifications. Auto capitalization of students and behaviors. Performance improvements.
Multiple Recordings - Introduces the ability to execute multiple recordings at once. (Finally!)
New Observation Timing - Introduces the ability to prompt for observations at minimally variable intervals in addition to start, end, and variable.
Today Extension Widget - Record observations directly on the today screen widget without entering the app.

Ratings and Reviews
Pretty good, but need detailed results
I like that the timer automatically restarts. It's a great tool for interval data collection. A few minor things that would improve the usefulness of the app: (1) sometimes I need to terminate the session before the total session time that I input. The results displays the number of yes intervals over the number of original intervals instead of the number of completed intervals when the session was terminated. Although I can figure out when I t'd, if I am having someone else collect data and looking at the results later, I cannot tell. I'd recommend adding the number of intervals completed or when the session was canceled to the results. (2) i would like to be able to run the app in the background while doing other things. With push notifications, the app will tell me that it is time to record data but you have to go back into the app to actually do it. It would be great if you could just record it in the notification/alert without going into the app.
Can’t record observed behavior
You need to do an update and fix your bug. I just downloaded this interval timer as part of the $10 timer package and am completely disappointed. I am trying to record and observe a student’s off-task behavior in 10-second intervals within a 15 minute observation period, and was excited about the appropriateness of this app. However, once I set the timer up and ran it, I was only prompted every 3-5 intervals with the opportunity to record whether the behavior was observed or not observed. In this case I need to record with pen and paper, not a big deal except that the app does not make a chime noise or even vibrate at the end of each interval, so this app does not make my data recording any easier whatsoever. Extremely disappointed that I wasted $9.99. Was really hopeful about this as it seemed really appropriate for behavior recording in an ABA classroom. Add the option of a simple chime and/or vibrate at the end if each interval and fix your bug of the prompt to record behavior and this will be great. Wish there had been more reviews for me to read before spending my money. Lesson learned.
Bug fix needed
There appears to be a bug in the app where it stops prompting to record if the behavior was or were as not observed about two-thirds of the way during a 20 minute or longer observation. I really want to use this app as part of my classroom observations but it impacts my data when I can no longer record behavior observations. I also have to record via paper and pencil, which doesn't exactly make this app useful.
With Family Sharing set up, up to six family members can use this app.
