LaFonten is a small, focused software studio founded in 2024, creating carefully built mobile apps designed for everyday use. Its portfolio brings together two distinct experiences: Ariadne, a mental-wellbeing app for clearing persistent thoughts, and +3-1, a logic game that exercises strategic thinking. The studio says its history began with building market-making and low-latency high-frequency trading systems before turning its attention to consumer apps.

Ariadne offers a five-minute thought-clearing ritual for people who overthink. Users can write or speak about what is on their mind, then respond to short, focused questions from AI to distinguish what they know, fear, and can act on. The process turns reflections into cards, helping users set a thought aside and return to their day. LaFonten notes that Ariadne is not a substitute for therapy or medical treatment.

+3-1 is a four-digit number-guessing game with no repeated digits. Players use clues to solve puzzles, compete against a bot or online opponents with ELO rankings, challenge friends by room code, and explore puzzle levels.
