My Messages

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.

Five rounds to get a widget right

The home screen widget used to snap to three fixed sizes, so anything in between wasted space or got cramped. Rebuilt it to read its actual size continuously and lay itself out for whatever shape it's given — took five rounds against real on-device screenshots to get the spacing honest.

My Messages · Jul 2026
The gradient that broke the launcher, not the app

A bitmap-based gradient on the floating badge crashed — but not in our logs. It was crashing the phone's launcher trying to inflate a stale resource reference, which only showed up in the launcher's own logcat. Swapped it for layered flat colours instead.

Never punish a lapsed subscriber

Pro features now gate at render time only — your chosen colour theme or badge style is never overwritten if a subscription lapses. Resubscribe and everything you picked just comes back, automatically.

The studio

One maker, one cat, lots of ideas.

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.
