AgaNool அகநூல்
A Tamil-first, privacy-first, offline-first personal OS for Android. One app to keep finance, farm, family, notes, journal, panchangam and traditional tools — all on your own device.
Live on Google Play · Android 5.0+ · Free
Everything in one app · எல்லாம் ஒரே இடத்தில்
One app. Twenty-three things it can do.
Most families juggle these across paper notebooks, WhatsApp threads and half a dozen apps. AgaNool brings them under one roof — with a shared search, shared quick-capture, and shared calendar-with-panchangam underneath.
The home screen
Everything you glance at, in one panel.
The Dashboard is the first thing you see when you open AgaNool. A greeting in Tamil, a live panchangam ribbon for today, a Quick-Capture bar, a strip of today's tasks and a running "spent today" figure — no scroll needed.
- Panchangam ribbon — Tamil year · month · day · tithi · nakshatra · paksha, with today's Rahu window called out
- Quick-Capture bar — one tap opens the classifier
- Today's tasks — with priority colour on the checkbox
- Spent today — live from your expense entries, in Indian grouping
- Header — search and a More grid for the non-nav modules
A real astronomical engine · not a table lookup
Panchangam that recomputes for your place, every day.
Most Tamil apps ship a static almanac. AgaNool ships an engine — a self-contained ephemeris (no data files, no network) with Lahiri sidereal correction, sunrise and sunset computed for your home coordinates, and end-times for each anga by linear speed extrapolation. IST-fixed.
- Tithi, nakshatra, yoga and karana — with sunrise-anchored values and next end-times
- Tamil year name from the 60-cycle (anchor: 2026 = Parabhava)
- Tamil month and day, computed astronomically
- Rahu, Yama, Gulika bands as clock windows for your latitude, not a national approximation
- Values verified on-device against a reference almanac
The Quick-Capture classifier
Type anything. AgaNool figures out what it is.
The pain of typical organizers is deciding where a thought goes before you can capture it. AgaNool's classifier does that for you. Type a line, and it routes it to task, note, event or expense — with the right amount, category, due date or start time already extracted. Wrong guess? Tap any chip to override.
- "coffee 90 tomorrow" → Expense · ₹90 · Food & drink · tomorrow
- "call Ravi Friday 4pm" → Event · Friday 16:00 (Rahu-aware)
- "buy rice, dal, oil" → Task · list · today
- "salary 45000" → Income · ₹45,000 · Salary
The classifier runs entirely on-device — no LLM, no server call, no model download. It's a few milliseconds on any Android phone.
The Tools hub
Seven traditional utilities. One tap away.
The Tools hub is where AgaNool packages the things a Tamil household actually reaches for — the land measure your surveyor knows, the numerology your parents believe in, the calendar converter that reads a Gregorian date and answers in the Tamil month, and the Porutham that tells you which nakshatras pair well.
- Land measure — sqft, cent, sqm, ares, ma, kaani, veli, kuzhi and the construction Square
- Numerology — Chaldean compound → root with the full letter table
- Tamil numerals — a live converter plus a reference sheet
- Date converter — Gregorian → Tamil year, month, day
- Muhurta — clear windows, computed from sunrise/sunset minus the inauspicious bands
- Manaiyadi / Vastu — aayadi shadvarga in feet or muzham
- Porutham — 10-poruttham compatibility between two saved people
People with birth charts · ஜாதகம்
Save a person. Get their chart.
Add someone to People with their date of birth, an optional time of birth and their place of birth, and AgaNool computes their rasi (moon sign) and nakshatra immediately — both geocentric, so location and time are optional for those two. Give it a time and a place too, and you get the lagna (ascendant). Everything computed on the device; nothing sent anywhere.
Rasi ராசி
Moon sign, geocentric — needs only the date of birth. Computed instantly and stored with the person.
Nakshatra நட்சத்திரம்
Lunar mansion the moon sits in at birth. One of 27; drives the Porutham compatibility tool.
Lagna லக்னம்
Ascendant — needs birth time and place. Computed on-device from the sidereal calculation when both are provided.
Three promises
Private. Offline. Tamil-first.
Not marketing bullets — these are architectural choices. Every feature above is built to keep the three intact.

Offline-first
Built to work wherever you are — the internet is optional.
- Every feature runs without a network

- Optional local-Wi-Fi peer-to-peer sync between your own devices
- Nothing routes through our servers
- Uninstalling removes everything from the device
Tamil-first
Designed in Tamil from the ground up — not translated.
- Tamil interface with English as an option

Sync between your own devices · சாதன ஒத்திசைவு
Local Wi-Fi. No cloud, ever.
Pair two of your own devices, and AgaNool syncs directly between them over the local network — never through our servers. The reconciliation is event-sourced with a per-device version vector, so records converge cleanly no matter which order the events arrive in.
