No score is invented. Each return begins at a prior close and ends at the next open.

Measuring Return Cadence from Session Timestamps

Read the explanation

App Return Gap Lab converts paired session start and end timestamps into chronological time spent inside and outside the application. Each return gap is calculated from the prior session close to the next opening timestamp, isolating idle interval length. When users test quick returns, the engine compares every gap against the threshold, tallying rapid re-engagement and median cadence.
