Mona on duty · 3 calls screened
Brokers, loan agents, delivery, the gate, a number you half recognise. Every one costs you the same thing: you stop what you're doing to find out it wasn't worth it.
Mona holds Android's caller-ID role, so every incoming call passes through it. Not in your contacts? Silenced before it reaches you.
It greets the caller as your assistant — politely, in whichever language they speak — and never pretends to be you.
The caller speaks, Mona replies, and it captures the detail that matters — name, reason, amount, gate number, order id.
A short summary lands in your WhatsApp, with the full transcript waiting in the app. Calling back, ignoring, or blocking stays your call.
Not a mock-up — a transcript pulled straight off the line.
You don't open an app to check. Who called and why lands in your WhatsApp — chai pe, meeting me, kahin bhi. The full transcript waits in the app if you want it.
1 call handled · summary sent
Mona says it's an assistant and that you're unavailable. It doesn't agree to anything, confirm anything, or pretend to be you.
No personal details, no OTPs, no payment information — whatever the caller claims to need it for.
Anyone in your address book reaches you untouched. Only unknown numbers are screened.
Mona reports and stops. Calling back, ignoring, or blocking stays your call.
Free, no account beyond your number, and you can turn it off from the home screen at any moment. Sideload build — your phone will ask you to allow installs from this source.
