TheCrazyCat builds playful, genuinely useful Android apps — the kind that do one thing brilliantly and don't get in your way. Here's what we're making.
Live on the Play Store, playable in your browser, or cooking in the workshop.

BingoNingo Bingo Caller
A complete 90-ball UK bingo caller. Clear text-to-speech calling, QR card scanning and automatic win checking — one device hosts, players join from their phones.
Digital 90-ball player cards to replace paper sheets. Every card has a QR code for instant setup — play three at once, or switch to Big Card mode for one large card.
Never miss an important call again. RingReminder gives you a gentle heads-up when your phone is on Do Not Disturb, silent or low volume — so the calls that matter don't slip by.
Your phone receives dozens of notifications a day. Most don't matter. My Messages sits quietly in the background, reads every notification, and keeps only the ones that are genuinely important — NHS appointments, family messages, bank alerts — in one clean inbox.
Improved the caller layout so it scales cleanly across every screen size.

First playable rounds are coming together — early testing soon.
Devlog · coming soon
Behind the apps — notes from the workshop.
We're starting a devlog to share what we're building, what broke, and what we learned along the way. Bingo logic, win-checking, the odd cat photo — it'll all be here.
TheCrazyCat is a small independent developer in the UK, building Android apps that are playful to use and genuinely helpful. The goal is simple: apps that do one thing brilliantly, look good doing it, and respect your time.
BingoNingo was the first family — a full bingo system for clubs, pubs, charities and front-room games. QuizBlitz and RingReminder are next out of the workshop.
