ioncreature
A one-person studio building thoughtful tools.
ioncreature is a small independent studio — currently one person, working on Number Gym as the first product.
The idea behind Number Gym is simple: a brain-training app that actually scales with you. Each mini-game keeps its own Elo rating, so the difficulty stays in the flow zone — not too easy to feel boring, not too hard to feel discouraging. Around that core sit structured courses, a daily challenge, friends, and an arena — small social bits that make practice feel less lonely.
The app is built for the long run: no ads, no third-party trackers, all 20 languages translated and maintained, with a paid Premium tier for users who want to support the project and unlock extras.
