How do I organize my college classes in one app?
Verified on: October 27, 2026
In tudy, the subject is the foundation: you create a subject with a name and a color, and everything for that class lives inside it, from tasks and the focus timer to notebooks and flashcards. The Free plan includes up to 5 subjects, which covers a full semester for a lot of students. Pro removes the limit.
What a subject is in tudy
A subject is a folder that does things. The tudy Home screen is the list of your subjects for the semester, and each one has four tabs: Tasks, Timer, Notebooks and Flashcards. Whatever you do in there stays tied to the subject, which is how you can see later how long you spent on Calculus compared with Biology.
Every subject has:
- A name (2 to 40 characters).
- Its own color, from the palette or a custom one picked with an eyedropper.
- A position you set by dragging.
The list switches between grid and list views. On a computer it opens as a list, on a phone as a grid.
How to create and arrange your subjects
Tap the + on Home, type a name and pick a color. It takes about ten seconds. To rename a subject or change its color later, open its options menu (“Rename / Change color”). The same menu has a shortcut to the subject’s topics, which break a subject into smaller themes. See Topics for how that works.
One setup that works well: make one subject per course this semester and give them colors that look clearly different. In Stats, each subject keeps the same color it has everywhere else, so the time chart reads at a glance.
What lives inside each subject
- Tasks: with due dates, priority, difficulty and subtasks. More in Tasks.
- Timer: Pomodoro or stopwatch, always tied to the subject. Each subject remembers its own focus and break lengths.
- Notebooks: notes with a full editor, 2 notebooks per subject on Free. See Notebooks.
- Flashcards: decks you can link to a subject.
You can also keep tasks and decks that aren’t tied to any subject. But time you track with the timer always counts toward a subject, because that’s what feeds your Stats.

What tudy doesn’t do with subjects
- It doesn’t store grades or calculate a GPA. The focus is studying, not the gradebook.
- It doesn’t import your class list from the school portal. You add subjects by hand (and, on Pro, a weekly class schedule in the Calendar).
- Deleting a subject is permanent. Its tasks, notebooks, decks and its hours in Stats go with it. XP you already earned stays yours.
Quick questions
Do I have to create all 5 subjects at once? No. Add them as you need them. The plan limit only counts what exists.
Can I use tudy with no subjects at all? Yes. The Tasks screen accepts tasks with no subject, for things that don’t belong to a class. But if you’re organizing a whole semester, you get a lot more out of tudy by setting up your subjects first.
Does it work on my phone? Yes. tudy runs in your browser and can be added to your home screen. See Install on your phone.
Frequently asked questions
How many subjects can I create for free in tudy?
Up to 5 subjects on the Free plan. Pro has no limit. The limit is enforced in the database, not just on screen.
What happens if I delete a subject?
Everything inside it is deleted, including the study hours shown in Stats. The app asks you to confirm first.
Can I change a subject's color and order?
Yes. Each subject has its own color (including a custom one picked with an eyedropper), and you reorder them by dragging.
Does tudy calculate my GPA or grades?
No. tudy organizes your studying (tasks, deadlines, time, notes and flashcards), but it doesn't store grades or calculate a GPA.
