Choose a focus block

Set work and break periods that fit the task in front of you.

Check what you recall

Answer a flashcard from memory before you reveal it, then revisit it later.

Look back at your work

See focus time, card reviews, study days, streaks, and subject activity.

Study tools that work together

Work on a topic, then check what you remember.

Use a focus block to begin, flashcards to check your understanding, and your study activity to decide what to revisit.

01 · Focus

Choose a work block that fits the task.

Set a Pomodoro focus period and a break, then adjust either length to suit the work in front of you.

  • Focus and break intervals you can adjust

03 · Bring your own cards

Already have flashcards? Bring them along.

Import a compatible JSON file, map its question and answer fields, review the preview, and add the cards to a new or existing deck.

Rivio recognises common card-list shapes and lets you choose the fields yourself, so you can keep a deck that already fits your course.

04 · Your progress

See how your study time is adding up.

Look back at study time, completed focus sessions, flashcard reviews, study days, and your current streak.

The subject radar compares the five most active subjects using cards made and cards reviewed. Its labels come from the subjects you create in the app.

How to read your study progress

Notice your study days

A streak marks the days you studied; it is one detail in your routine, not a score of what you know.

Keep course files by subject

Organise subjects and open their PDF references from your library.

Set reminders that suit you

Choose the prompts you want and set them around your day.

Choose light or dark

Switch the appearance to suit your screen and study space.

From your course to your cards

Choose a subject. Focus on a task. Check what you remember.

Set a timer if it helps, take a break, then use a few flashcards to see what needs another look.

01

Pick a subject

Keep your decks and PDF references close to the course you are studying.

02

Focus, then recall

Work for a block that suits you, take a break, and try your flashcards.

03

Look back and choose

See your study activity and decide what would help you next.
