Hitasura

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.
