A view of the Couchd app: a live 47 minute study session on Gauss's theorem and applications, the Std 12 Science syllabus tree, coverage and mastery read separately, and today’s revision queue ordered by predicted recall.
One place for your syllabus, your revision schedule and everything you have actually learned. It stays with you from school through entrance exams and into college, so the only thing left in your head is the studying.
Right now, you are the database.
Five questions you answer from memory, all day, for years. Here is each one already answered.

Five background processes that used to run in your head. None of them are yours now.

Your syllabus
0 of 20 chapters mappedThis is your syllabus.
Every chapter you have to get through this year, and which ones sit on top of which.
Finishing is not the same as knowing.
A chapter you ticked off drops back. One you can actually solve comes forward. Most trackers average the two into a single number.
You will forget this. On a schedule.
Revision has to land before the gap opens. Whatever you only skimmed does not come back green.
Six years. One graph.
This year is the constellation you have been watching. Behind it: the entrance exams it feeds, the degree after that, and the years you have not started yet. One record, the whole way.

This is what the tracking actually looks like.
Four screens from one Std 12 Science student. Real chapters, real numbers.
Your syllabus, in the shape your book has it.
Subject, then chapter, then topic. Every row carries its own state. Each chapter gets two bars that never get merged: how much you have covered, and how much you can actually do. They are rarely the same number.

Board not in the catalogue yet? Build your own tree in a minute. When the verified version lands, your progress moves across to it.
The list that decides your evening.
Every topic has its own forgetting curve. Couchd works out the day your recall drops past the point where a quick review still fixes it, and puts the topic in front of you the day before.
You do not pick what goes on this list. That is why it gets done.
