Feynman rules vs PrecisionRush

This app introduces Feynman rules. You can get some understanding for Feynman diagrams. E is external point, V is vertex, P is propagator, and S is symmetry factor.

PrecisionRush is a timing game about one thing: stopping the clock at exactly the right moment. It’s easy to learn, but genuinely challenging to master. I built it to feel smooth and respectful of your time: no ads, no energy systems, no grinding. Just you, the timer, and your reflexes. What’s inside: Arcade Mode: Stop as close to the target as you can. Build streaks and push for higher scores. Multiverse Mode: Track multiple stopwatches at once for a tougher challenge. Daily Challenge: A fresh target every day, the same for everyone. Battle Mode: Go head-to-head against adaptive AI opponents. Zen Mode: Practice without pressure. No stakes, just timing. Your score is based entirely on accuracy: no luck, no pay-to-win mechanics, no shortcuts. Just timing and consistency. Earn XP, unlock achievements, build login streaks, and watch yourself improve over time. Clean visuals, satisfying effects, responsive controls, subtle haptics, and accessibility options like reduced motion. If you enjoy the game as much as I do, there’s an optional “Support the Developer” tip feature. PrecisionRush is a small game with a simple idea, but it rewards focus, patience, and the feeling of nailing that perfect stop.
