Everything Hitasura does.
A tracker, not a teacher. It records the immersion you already do and gives it a shape you can read.

Track
Getting a session in should take seconds, or you will stop doing it.
- Log a session
- Date, duration, what it was, and a note if you want one. Optional ratings for difficulty, comprehension and enjoyment.
- Timer
- Start the clock and log exactly what you did instead of estimating afterwards. Survives closing the app; pauses and resumes.
- Quick-log shortcuts
- One tap for the thing you log constantly. The shortcut fixes the category, activity and title; you fill in the duration.
- Backfill
- Log what you did last week. Backfilled sessions are marked, so they never distort what a typical session looks like.
- Spreadsheet import
- Bring an existing history across from .xlsx. Nothing is written until you have reviewed it, and re-importing recognises what is already there rather than doubling it.
Organise
The part most trackers stop short of.
- Languages
- Each keeps its own categories, activities, titles, goals, journal and analytics. Switching changes scope and never moves data.
- Categories
- Watching, Listening, Reading, Speaking and Writing to begin with — then rename, reorder, add and retire until it matches your life.
- Activities
- The level beneath a category. Podcast, audiobook and radio are three different habits, and your history should say so.
- Titles
- The actual show, book or podcast. This is what turns "58 hours of reading" into something you can recognise.
- Archiving
- Retire a category or activity without deleting anything. Every session and every statistic stays intact.
Understand
Every figure is computed from the sessions you logged. Nothing is estimated.
- Dashboard
- Today at a glance, with streaks and recent activity.
- History
- Every session, newest first. Filter, edit, bulk-select, and undo a deletion.
- Calendar
- A heatmap of every day you showed up. Click a day for the detail.
- Analytics
- Breakdowns by category, activity and title.
- Media
- Where your hours went, by title.
- Journey
- The whole thing as a timeline, in the order it happened.
- Journal
- A short note per day, beside how much you actually did.
- Insights
- Observations drawn from your own log — what grew, what slipped, how consistent you have been.
Stay with it
Motivation without the noise.
- Goals
- Daily, weekly or monthly targets, with your pace against them. Three on Free; unlimited on PRO, and scoped to an activity or a single title.
- Streaks
- Current and longest, counted in your own timezone and your own day boundary.
- Achievements
- Earned from what you have actually logged, not from opening the app.
- Personal records
- Longest session, best day, week and month. Per-category records on PRO.
Go deeper
Hitasura PRO is for people who want to understand the record, not just keep it.
- Advanced analyticsPRO
- Year on year, rolling averages, time-of-day and weekday patterns, custom ranges, and a deeper breakdown by title.
- Multiple languagesPRO
- Every language you are learning, kept completely separate.
- Written insightsPRO
- Your statistics, put into words. The figures are always computed first — the model phrases them and never invents one.
- Language ReportsPRO
- A weekly or monthly email about one language, in your timezone: totals, what changed, goals met, records set.
- Automatic backupsPRO
- Daily or weekly, kept privately, with history you can download or restore from.
- Bulk editingPRO
- Fix many sessions at once instead of one at a time.
Own it
Your history is yours, and getting it out is never the paid part.
- Spreadsheet export
- An .xlsx of your sessions, readable by anything, and re-importable here.
- Full backup
- A complete, versioned JSON copy of your whole account — every language, session, goal, journal entry and setting.
- Restore
- Put a backup back. Restoring replaces rather than merges, so it cannot duplicate your history, and it happens in one transaction — if anything fails, nothing changes.
- Delete everything
- Close the account and it is gone, along with all of it.
The shape of it
Five levels, so a session is a thing that happened rather than a number in a row.
