Mateusz Czechowski is an independent developer who creates small, focused apps for iPhone and Mac. Working solo, he builds each product around a distinct idea, with attention to visual detail and a clear, purposeful experience. His collection spans photography, games, health, and sports, with four apps listed as shipped and one in development.

Sticta, a Mac photo and wallpaper app in development, lets users turn their own photos into stickers, place them on a travel map, fridge-door layout, or free-form background, and use the result as a desktop. Pit Lane Tycoon is an idle iPhone game about growing a racing team from a karting garage. Weightfile tracks weight through seven-day trends rather than daily readings, presenting progress as a stamped case file. Intimoment is a private intimacy journal for quickly recording moments and exploring patterns, with no account required. In Target is an iPhone shooting-practice log based on ISSF rules, supporting training series, live shot-by-shot competitions, and inner-ten tie-breaks. Czechowski also provides app support and privacy information for selected products.
