Our apps

Four apps, one promise: everything works offline, nothing about you leaves your phone, and each app does one thing properly. Free with a single light banner ad; a one-time purchase removes ads for good.

Kakuro – Logic Puzzles Offline

A number-crossword with five difficulty levels, a fresh daily puzzle, and hints that teach the next logical step rather than just filling in a square. Every puzzle is verified to have exactly one solution.

Nonogram – Logic Puzzles Offline

Grid logic puzzles solved from number clues — also known as hanjie or griddlers. One solution in every puzzle, a daily with streak protection, and lessons that teach the real techniques.

EMI Calculator – Loan, GST, SIP & Tax

A suite of India-focused calculators in one offline app: loan EMI with part-prepayment, SIP and lump-sum returns, FD and RD, GST, and an income-tax regime comparison — every figure computed exactly.

Kundli & Panchang – Offline

Birth charts, gun-milan matching, Vimshottari dasha and the daily panchang, computed on your phone with real astronomical calculations — in English and Hindi. Your birth details never leave your device.

The rules every app follows

• Offline by default. Full functionality in aeroplane mode — the network is touched only for ads and the one-time purchase.
• No accounts, no tracking by us. There is no Northcell server; your data stays on your device (and in your own Android backup if you use one).
• Honest monetisation. One modest banner, one small one-time purchase to remove it. No subscription, ever.

Each app's privacy policy spells out the detail: Kakuro, Nonogram, EMI Calculator, Kundli & Panchang.
