The author built a simple messaging app for their family after their previous app, Tapstack, shut down. The new app, BoopSnoop, has only four daily active users and is distributed through TestFlight. The author views this project as a form of 'home cooking' - creating something personal and tailored to their family's needs. This approach to programming is seen as liberating and rewarding, allowing for a focus on personal connection rather than scalability or professionalism.
