Manifesto
Built for flow, not noise
Syntergy is your mental gym — difficulty that adapts, a short plan for each day, and progress that stays on your phone.
Soft calibration
Every level adapts its difficulty to keep you on the edge between flow and challenge — never punishing, never boring.
Your data stays here
Scores, streaks, and your profile live on your phone. We do not sell your training history. The app is free and may show ads; you can remove them with a one-time purchase.
Harmonized design
A single visual voice ties every game — from color to typeface — into one coherent experience you can trust.
Free, with a choice
