Intervals (e.g. Focal/Scan Samples, and more.)

Some behavioral research requires monitoring activity at (or during) intervals of time. This can be for focal or scan sampling in wildlife behavioral research, or time sampling in psychology. Additional uses include bounding monitoring periods.


Timestamped Field Notes now allows the ability to define configurations of intervals:

  • Name of interval configuration
  • Interval duration (hours and/or minutes)
  • Text to insert into the event to mark each interval
  • … and a few others.

These can be associated with an event or a keyword set (to have it apply to each event created with those keywords.)

Intervals are presented on the screen (see screenshot) as a count down above the data entry fields. Intervals can be paused, restarted and/or reset – where the start of interval time is changed to now.

This feature is entering beta testing phase, and anybody willing to give their feedback on this feature – to see if it works well for their uses – is asked to express their interest to

It is too premature to document this feature yet, but when ready it’ll be added to the Timestamped Field Notes documentation.

Interval Timers in Timestamped Field Notes?

I’ve received some interest in “interval timers” for Timestamped Field Notes, i.e. regular audible blips, notifications and/or automatic text inserts that occur at time intervals during the event data entry. The purpose is to segment the data, or initiate regular action from the user.

This feature would help support behavioral sampling (e.g. scan sampling, instantaneous sampling) but maybe also other purposes for your need.

If interested in helping specify this feature, please comment here, or send your thoughts to or answer these quick questions:

Thanks in advance for your feedback.
