For high school students

School from 8 to 3, coaching, tuition, a social life — and somehow the syllabus too. This is the part that fits.

Built around the school day

Exam Mode is school-hours-aware by design: study blocks land around classes instead of through them, and an optional calendar connection adds tuition, coaching or shifts to the picture. The countdown to each exam drives how the remaining days are paced.

The app assumes phone-first use — it runs in the mobile browser and installs as a PWA. No app store, no storage cleanup prompts.

Free where it matters

Core planning, focus timer and streaks are free — no ads, no data selling, no card. Guests get free AI messages to try the whole loop before creating an account.

Privacy is the teenage condition too: plans stay on your device until you choose to sign in, and the Privacy Policy spells out exactly what syncs. Made for ages 13 and up.

Locked In was designed around the students most planners fail: the ones who freeze at the start, juggle classes with deadlines, study in the wrong hours, or meet their deadline the night before. Pick the situation that sounds like yours — the pages below explain exactly how the app handles it.
