Enfocando: Study Timer & Plan

Enfocando is a study app with a study timer, subject cycle, spaced repetition and a weekly study plan. Study with focus, review at the right time and watch your consistency grow, with no sign-up and your data stored on your own device.

Built for anyone preparing for civil service exams, college entrance exams, the bar exam, university courses or certifications.

How it works
Pick a subject, tap Start and study. When you finish, the app logs the session, schedules the review and updates your goals and charts. Every minute studied becomes progress that lasts.

Focus blocks
• Focus and break cycles with adjustable length and a long break.
• Optional focus sound: white, pink or brown noise to mask distractions.
• Full sound mixer with ambient layers, rain and more.
• Free-running timer for those who prefer to study without blocks.
• Reminders and a home screen widget to start without opening the app.

Spaced repetition
• After each review, mark Easy, Medium or Hard and the app schedules the next one.
• A queue with only what is due today, so nothing piles up.
• Configurable review time and daily reminder.

Study plan and cycle
• Automatic plan: enter your free days and minutes, and the app spreads the week's subjects by weight, difficulty and coverage.
• Manual cycle: set the order of subjects and follow it block by block, with a minute goal per round.
• Separate goals, each with its own subjects and cycle.

Goals and performance
• Daily and weekly goals in minutes, with a progress bar on the Today screen.
• Charts of hours per day, 12-week consistency and question accuracy.
• Mock exams logged with score and weak spots per subject.
• Full history with filters and session editing.

Study materials
• Books, PDFs and handouts with ""stopped at page X"".
• Reading pace and estimated finish date checked against your exam date.

Your data is yours
• No sign-up, no login, no mandatory cloud.
• Subjects, sessions and reviews stay on the device only.
• JSON backup made by you, to move everything to a new phone.
• Light and dark theme, in English, Spanish and Portuguese.
