HOW IT WORKS Races are structured as high intensity interval cardio workouts with differing periods of work and rest. We post new races every week and they take place across different maps like Miami Beach, Ashokan Forest, Space, and more. Each workout is unique and different. The higher your heart rate, the faster your character goes! BUT be careful not to push yourself too hard; if your heart rate goes above 90% of its maximum, it will overload your Hyperpack and slow your character down. The key is to find the sweet spot where you're pushing yourself to your limit but still able to maintain your pace and stay in the lead! THE ULTIMATE FITNESS GAME YDY features exciting racing maps, endless entertainment, and even includes powerups called Treats that allow you to shoot fireballs, get a speed boost, and become invincible. YDY powerups and surprises add extra elements of fun that make this app an ADRENALINE RUSH of a fitness game. TAILORED, AI-POWERED GAMEPLAY YDY is powered by AI which adapts to your specific fitness ability. As you improve over time, the AI adjusts to keep pushing you to your limits!  You'll never get bored with the same old races, as YDY ensures that every race is different and challenging.

Instead of being able to co-run with my Apple settings, it shuts it down and gives me no information about my cardio afterward. There are plenty of other workout apps that can coexist, and I would recommend one of those instead. ### 1/5 — Doesn’t deserve the one star *2024-01-08* Was looking forward to using this app! The app won’t load to start the races! A waste of time! Do better! ### 1/5 — This is the worst app *2023-08-31* No even the registration screen works well. How did an app like this made it to the App Store? ## Frequently asked questions about YDY ### What is YDY? YDY is a fitness game that uses your heart rate to power kart-style races.
