BuzzzMind makes small, focused iPhone apps. Each one does a single thing and tries to do it well.
BuzzzMind is a one-person studio run by Dunca Vlad. Both apps are on the App Store for iPhone and are free to download. Each app has its own page here, with guides on the thing it helps with: a question game to get a group talking, and a habit tracker to help you show up every day.
