Focus sessions that count real time
The timer runs on wall-clock time, so it survives a locked phone or a backgrounded tab. When it ends you say what actually happened — and only honest minutes are logged.
Sirt9ra — “go study”
The study system that
keeps you honest.
Most study apps reward you for opening them. Sirt9ra only counts the time you actually focused, schedules the revision you'd otherwise skip, and tells you exactly what you need on the final — while there's still time to do something about it.
No card, no trial timer, no ads. Export or delete your data whenever you like.
Everything in one place
Six tools that actually change your week
Not a timer with extras bolted on. Each piece feeds the next: sessions build the analytics, assessments drive the forecast, and the forecast tells you where to focus tomorrow.
Spaced repetition, scheduled for you
Cards use SM-2 with proper learning steps, so new material is drilled before it's scheduled. Reviews spread across days instead of piling into one impossible Tuesday.
Know what you need on the final
Enter your assessment weights once. See your current grade, your projected grade, and the exact mark you need on what's left — before it's too late to act on it.
Every deadline in one place
Exams, coursework hand-ins and your weekly timetable, with a countdown to the date that actually matters.
Analytics that tell the truth
Which module you're avoiding. What hour you focus best. Whether this week was genuinely better or just felt that way.
Built around how memory works
Intent before you start, a single subject at a time, and a review schedule that spaces itself. The app nudges toward the habits that are actually evidenced.
Privacy by construction
Your study data is nobody else's business
There is no analytics pixel, no ad network and no third-party script on any page. Security isn't a setting here — it's where the data lives.
Row-level security on every table
Access rules live in Postgres, not in the app. Every query is filtered by your user id before a row is ever returned.
Your stats can't be faked
Streaks and totals are computed by the database from your session history. Nothing in the browser can write them — not even you.
Export or delete, any time
One click gives you every row you own as JSON. Another deletes the account and cascades through every table. No dark patterns, no retention period.
Your next session is the one that counts.
Set up takes about a minute: your modules, your term, and a daily goal you'll actually hit.
