Syllabus Tracker — Chapter-by-Chapter Progress

The syllabus tracker is the spine of the app. Almost everything else — your countdown, the study planner, the focus timer, the analytics, your home-screen widgets — reads from it. It answers one question that a plain countdown never can: not how long is left, but how much is left.

The structure is simple on purpose. Subjects contain chapters, and every chapter carries its own progress. Everything else is built on top of that.

There are three ways, and you can mix them freely.

• Add a subject by hand. Give it a name, pick a colour, and say how many chapters it has. The app creates them as Chapter 1, Chapter 2… and you rename them as you go. Useful when you know the shape of a course but not the chapter names yet.
• Add chapters one at a time or in bulk. At any point you can add more chapters to an existing subject, rename them, delete them, or drag them into the right order. Subjects can be reordered too — and the order syncs across your devices, so the list looks the same on your phone and your tablet.
• Smart Import. This is the fastest route for a real syllabus. Paste your syllabus text, or upload the PDF your board or university published, and Diya reads it and splits it into subjects and chapters for you.

Two things make this safe to use:

• You always see a preview before anything is imported. Every subject and every chapter comes with a checkbox, all ticked by default. Uncheck the papers you're not sitting, the optional units, the appendix that isn't examinable — then import only what you actually study.
• It works without a subscription. If you don't have AI Pro, the app hands you a ready-made prompt containing your syllabus text. Copy it, paste it into ChatGPT, Gemini or Claude, paste the answer back, and the same preview appears. You get the whole feature, you just do the round trip yourself.

Imported subjects are automatically given distinct colours from a preset palette, so a long list stays readable at a glance.

Every chapter sits in one of four states, and you set it with a single tap:

Skipped is not the same as not started, and that distinction matters. A skipped chapter counts as fully dealt with — it stops appearing as work you owe, it stops dragging your progress percentage down, and the study planner drops it from your calendar and never schedules revision for it. It's how you say "I'm not doing organic chemistry's last two chapters, and I've decided that on purpose" without the app nagging you about it forever.

Four states aren't enough for a chapter you're halfway through, so every chapter also has a progress slider from 0 to 100%, adjustable one percent at a time.

The status and the percentage are two views of the same thing and are always kept in agreement:

• Tap Completed → the chapter jumps to 100%.
• Tap Not started → it drops to 0%.
• Tap In progress → it moves to at least 10%, so the bar visibly leaves zero.
• Drag the slider to 100% → the status becomes Completed on its own.
• Drag it to 0% → back to Not started.
• Drag it anywhere in between → In progress.

You never have to keep the two in sync by hand, and you can work whichever way suits you — some students only ever tap the tick, others live on the slider.

A subject's progress is the average of its chapters, where completed and skipped chapters count as a full 1.0 and in-progress chapters count for however far along they are.

So a subject with 10 chapters — 4 completed, 1 skipped, 1 at 50%, 4 untouched — reads as 55%. Every chapter carries equal weight, which keeps the number honest and predictable: nothing is silently weighted behind your back.

If you run a focus session on a specific chapter for at least a minute, that chapter is automatically promoted from Not started to In progress. You don't have to remember to flip it.

This only ever moves a chapter forward from Not started. It will never touch a chapter you've already marked In progress, Completed or Skipped — your own decisions always win over the automatic one.

The timer also records how much time you've spent on each individual chapter, so a chapter's card shows both how far through it you are and how long it has cost you. Those two numbers together are what tell you a chapter is heavier than you expected.

This is the part that isn't visible but does most of the work.

Whenever a chapter's progress changes, the app records how much it moved and on which day — not just the new total. Your syllabus therefore carries a full daily history rather than a single current number.

That history is what powers:

• Your daily progress figures in analytics — real syllabus coverage gained today, not just minutes on a timer.
• Your study pace, measured over a rolling 14-day window. Long enough to survive a couple of idle days, short enough to notice a genuine slowdown. A student who's picked up speed this week is judged on this week, not on a slow start a month ago.
• Your exam forecast (below).

For every subject with an exam date, the app takes your measured pace and projects where your coverage lands on exam day:

• Ready — already at 100%.
• On track — you'll finish with room to spare.
• Tight — you'll finish, but you'll be using more than 85% of the time you have left.
• Short — at your current pace you won't finish. It tells you how many days late you'd be.
• Not enough data — you haven't logged enough recent progress to project anything, and it says so instead of guessing.

Subjects are sorted with the soonest exam first, because that's the one you can still do something about.

This is the biggest idea in the tracker: every chapter has two independent progress records. One for learning it the first time, one for revising it.

Your revision progress has its own status per chapter, its own percentage, and its own dated history. Finishing a chapter doesn't touch its revision progress, and revising it doesn't alter your original coverage. Both bars are visible for every subject.

Revision runs in numbered cycles. When you finish revision round 1 and start round 2:

• Every chapter's round-1 result is archived, so you can look back at which chapters you actually completed in each past cycle.
• The cycle's allocated time versus the time you really spent, and the number of days it actually took, are recorded. Over two or three cycles you learn how badly you underestimate revision — which is exactly the number you need to plan the next one.
• Every chapter resets to Not started for the new cycle, and the new cycle's day allocation is applied.

The Revision Planner lets you lay this out in advance: how many rounds you want and how many days each gets. It starts you at a sensible 6 days, then 3, then 2 — rounds get shorter as material gets familiar — and spreads each round's days evenly across that subject's chapters. You can then adjust any individual chapter's allocation by hand.

Revision timing starts when you do. The first time you mark revision progress on a subject, the app asks before starting that subject's revision clock, so it doesn't start counting days behind your back. If you're already revising other subjects, it warns you that you'll be working from a shared pool of days across all of them, and lets you back out.

If you need to start over, you can reset the current cycle's progress or reset just the day count — resetting the days gives you your full allocation again from today, and explicitly does not touch your chapter progress.

When you mark a chapter complete, the app can create three to-dos for you automatically: revise it on day 3, day 7 and day 30. That's spaced repetition at its simplest, and it means finishing a chapter doesn't end your relationship with it.

Two details worth knowing:

• It's a setting you can turn off, if you'd rather your to-do list stayed entirely yours.
• If you're using the Study Planner, these are automatically suppressed — the planner already schedules its own spaced recall and revision cycles, and duplicating them would give you two lists telling you different things.

Each chapter is more than a checkbox:

• Notes — formulas, definitions, mistakes to stop making. Kept with the chapter, so they're where you'd look for them.
• Time spent, from your focus sessions.
• Importance bars (up to five, filled like a phone's signal meter), when you've run a past-paper analysis for that subject. These are scored from how often the chapter has actually appeared in past papers — from Not rated through to Critical importance. It's the difference between a syllabus in printed order and a syllabus in the order that will earn you marks.
• Predicted questions, from the same analysis.
• A quiz offer on completion — mark a chapter done and, with AI Pro, you're offered a quick quiz on it, so "I've finished it" gets checked rather than assumed.

Your syllabus isn't a standalone checklist:

• The Study Planner reads it directly. Completed and skipped chapters are dropped from your calendar; partly-finished chapters are scheduled for only the part you have left.
• And it writes back. Ticking a study block in the planner moves that chapter's percentage here. Finish one of a chapter's three blocks and the chapter reads 33% everywhere in the app — the calendar, the syllabus tab, the home screen and your widgets all agree.
• Marking a chapter complete or skipped here settles its leftover blocks in the planner, so closed chapters can't haunt you as permanent overdue work.
• Home-screen widgets update on every change, so your progress is visible without opening the app.
• The Diya dashboard turns it into pace bars and forecasts rather than raw percentages.

• Deleting a subject moves it to the Recycle Bin, not into the void. You can restore it. Bin items and their deletion records are cleared after about 10 days.
• Deletions sync properly. A subject you deleted on your phone doesn't reappear from your tablet — the app keeps a record of what was deleted, precisely so a sync can't resurrect it.
• Sync merges at the item level using timestamps, so editing different subjects on two devices doesn't make you choose which device wins.
