Log your prep. See your patterns.
StudyGauge tracks the study sessions you log and the mistakes you make on practice tests — then shows you where your time is going and where you keep losing points. It doesn't generate quizzes or tutor you; it's a logbook, not a classroom.
Built for SAT PSAT ACT prep — or set up a custom exam type.
How it works
Log a study session
Subject, topic, and minutes spent — logged in a few taps after you close the book.
Log assessment mistakes
Go question by question on a practice test and tag why you missed each one.
See your patterns
Your weak subjects, modules, and recurring error types surface on their own.
What you get
Study time, broken down
See where your practice hours actually went — by subject and by day, not just a running total.
A weak-spot heatmap
Mistakes plotted by subject and module, darker where they pile up, so patterns are hard to miss.
Error-type patterns
Careless slip or a real content gap? Tag every mistake with why, and watch which reason keeps coming back.
Your prep, measured.
Free to use. No credit card, no ads, no content you didn't put there yourself.
