Today is sharper. Your daily session now leads the Today screen: one tap and you're training. Can You Catch It? sits right below as a quick game, and every other experiment lives in Drills. Reactra is now fully focused on what it does best: reaction, vision and sound. The readiness check-in stays, and links you to AthleteMania for full mobility routines. Plus small fixes and polish.
