How it works
From paper notebook to digital ledger in 3 steps
No setup forms. No accounts. Open the app and start tracking in under a minute.
Install Konnach
Download from the App Store. The app weighs around 30 MB and runs on iPhone & iPad.
Add a client or supplier
Type a name (and optionally a phone number). That's it — no email, no signup.
Track every transaction
Tap “I gave” or “I took”. The balance updates instantly. Send a WhatsApp reminder when needed.
Privacy by design
Your financial data,
stays on your device.
Your business data belongs to you. That is why Konnach is offline-first. No cloud servers, no third-party access, no analytics that follow you around.
Face ID & PIN
Biometric and PIN authentication restrict access to your ledger. Only you can open the app.
Local SQLite
An industrial-strength local database keeps every transaction on your device — never on a server.
No Internet Needed
Works in basements, markets and rural areas with poor reception. Zero latency, ever.
You Own Your Backups
Export an encrypted backup any time and store it where you want — your phone, your drive.
