Quick answers
What is ROID AI?
ROID AI is a personal fitness, nutrition, and training coach you chat with like ChatGPT — but built around your fitness. It gives evidence-based workout, nutrition, and recovery guidance, logs meals, remembers your injuries and preferences, and adapts to your goals.
Is it free to start?
Yes — create an account and ask ROID AI a couple of questions on us. To keep going without limits, you can continue with a subscription. The ROID iOS app is always free to use, with AI credits that renew every month.
Does my web chat sync with the ROID app?
Yes. Your account and your conversations are shared — start a chat on the web and pick it up in the app, or vice-versa. When you install the app and connect Apple Health, the same coach gains your live training, sleep, and recovery data for deeper personalization.
Do I need to install anything?
No. ROID AI runs right in your browser on any device. Installing the free ROID iOS app adds live Apple Health personalization and on-device reminders, and your chat history is already there.
What can ROID AI actually do?
Build and adjust training guidance, answer nutrition and supplement questions with research citations, log and remove meals, track macros, remember durable facts like injuries and allergies, and surface your trends. Some features — live Apple Health data and on-device reminders — are unlocked by the free iOS app.
