Which citation styles do you support?

The citation generator supports APA (7th edition), MLA (9th edition), Chicago (17th edition), and Harvard referencing styles for books, journal articles, and websites.

How are readability scores calculated?

The essay word counter uses standard readability formulas that analyze word length, sentence length, and syllable counts to estimate a reading level and reading time for your text.

Can I use these tools on my phone?

Yes. All education tools are fully responsive and work on any modern browser — Chrome, Safari, Firefox, Edge — on phones, tablets, and desktops.

Do flashcards sync across devices?

Flashcard decks are stored in your browser's local storage. They persist on the same device and browser but do not sync automatically across devices. You can export and re-import your cards if needed.

What is the Pomodoro technique used in the Study Timer?

The Pomodoro Technique breaks study time into focused intervals (typically 25 minutes) followed by short breaks (5 minutes). After four work sessions, you take a longer break (15-30 minutes). This method improves focus and prevents burnout.

Can I track study time per subject?

Yes. The Study Timer lets you enter a subject name before each session. It tracks total study time and session count per subject, giving you a clear picture of where your time goes.

How does the grade calculator handle weighted grades?

You can assign different weights (percentages) to each assignment or category. The calculator computes your weighted average and shows what grade you need on remaining work to hit your target.

Are there more education tools coming?

Yes! We're actively adding new tools. Check back regularly or follow our updates for new additions to the education toolkit.
