# Professor Index vs Teacher Meter

Written reviews complicate that: 88% of Professor Index's written reviews are positive against 100% of Teacher Meter's, so the app with the better star average is not the one people write more warmly about.

Professor Index ships an update monthly, Teacher Meter every 9 days. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
