Todait is a study planner for big exams and long courses. Add what you need to finish, set your deadline, and get one realistic study portion for today. When you miss a day, Todait recalculates the rest of your plan so you can keep going without starting over. Big exams aren't won in a panic. They're won in quiet, steady days. HOW IT WORKS Tell Todait what you need to learn and by when. It counts backward from your exam date, weighs what's left, and gives you today's portion — not a guess, real arithmetic. And when a day slips away — and some days will — Todait rebalances the rest. No restart screens. No catch-up guilt. Just today's revised plan, ready when you open the app. WHAT TODAIT DOES — Spreads your full prep evenly across the days you have left — Sets daily portions from real pages, lectures, sections, or practice sets — Rebalances automatically when you miss a day — Shows progress by chapter, by week, by deadline — Runs multiple plans for multiple subjects at once — Keeps separate flows for reading, watching, practicing, and assignments A REAL 24 DAYS WITH TODAIT Day 1 — You enter "MCAT Biology review book, 320 pages, finish in 24 days." Todait answers: 14 pages today. You do them. Day 8 — A long shift, a hard day. You read nothing. No guilt — Todait quietly works the miss back into the days ahead. Day 9 — You open the app. It says 16 pages: yesterday spread across the days left, not dumped onto tomorrow. Still doable. You keep going. Day 24 — The book is done. Every page is behind you. You didn't cram, you didn't burn out — you arrived steady, one calm portion at a time. WHY TODAIT Most study apps hand you an empty checklist and leave the hardest part to you. Todait carries it — the arithmetic, the rescheduling, the constant "am I on track?" — so all you carry is today. A big exam doesn't have to feel big. The right plan makes today lighter. Open Todait, and see today's number. Today, toward your dream.

Verdict

The call
