CRI Plus
How long the wait usually runs. It reads the applications you already logged, works out which milestone you are waiting on, and compares that wait against what past applicants reported.
It reads the Application Tracker
There is nothing to type in twice. The schools, statuses, and dates come from the rows you keep on the Application Tracker, which is free, and every prompt on this page to add or correct something links back there. If a row is missing the month you applied or the month your invite arrived, this page names that gap instead of quietly leaving the school out.
What it gives back
The benchmark shown depends on where you actually are. Waiting with no response yet, the relevant comparison is how long invites took for other applicants at that program; holding an invite, it is the wait to interview and then to a decision. Milestones you have already passed drop out, so the timeline stays pointed at what is still ahead rather than restating what already happened. Where you supplied an exact submission day the wait is counted in days, and where only the month is known the page says the count starts from the first of it.
Comparing against applicants like you
Optional, and off until you turn it on. Point the timeline at your latest CRI calculation or any saved result, and the comparison narrows from everyone who applied to that program to the applicants whose cumulative GPA, science GPA, and test score sit near yours. Where enough people reported exactly your numbers it uses those; where they did not, the tolerance widens a step at a time and the page states the band it settled on, naming the GPA and test-score range it accepted and how many applicants that left.
