Stratum: Study & App Blocker

The only focus timer that knows your deadlines. Block distracting apps, track study time by subject, and never miss an assignment or exam again.

Reclaim your study time with Stratum, a focus timer, app blocker, deadline planner and study tracker built for students.

Choose what you need to study, block distracting apps, start a focused timer, and track your progress over time. Stratum helps you stop doomscrolling, stay locked in and build better study habits one session at a time.

Whether you are preparing for exams, catching up on lectures, finishing assignments or trying to build a consistent study routine, Stratum gives you the structure to focus now and the insight to improve later.
