FriendlyPear is an open-source Android app that stops scams before money moves, and checks with the family before anything risky happens. It's made for older adults first.

The problem: in 2025, Americans aged 60 and over reported losing $7.7 billion to online fraud (FBI IC3). Scams win by isolating people and rushing them: "Hi Mum, it's me, new number", or "Your bank here, read me the code".

The solution is Peri, a friendly clay pear who lives in the phone. She checks texts, WhatsApp, email and browser notices the moment they arrive, and flags a stranger's call before pickup. A code arriving during a call is a scam, full stop. Before anything risky happens, she checks through a second channel: the real family member, at the number already saved, with a one-tap approval link (No / Call me first / Yes). The family never reads messages, calls or location. Only doubtful messages ever leave the phone.

Rules on the phone decide first, and no model can override them. Meta's models are asked only when a message is doubtful, and their vote is capped. On 200 hand-written messages the rules were never tuned on, 91% of scams were flagged. 401 tests, English and Spanish, MIT license.

All product code was written during the hackathon (Oct 27 - Nov 4, 2026). Concept and design documents were drafted before.
