# Fit Trainer > Fit Trainer is a chat-based AI personal trainer app for iOS and Android. You train with it by conversation: it builds a personalized workout plan from your goal, schedule, equipment, and injuries; guides you through every set right in the chat with exercise photos, videos, and step-by-step instructions; logs your sets; and rebalances the remaining workout in real time. It applies progressive overload from your logged history, always in weights you can actually load, auto-builds warmup sets, and adapts when you miss sessions or change equipment. Unlike most AI workout apps that just generate a plan and leave you to it, Fit Trainer coaches you through the whole session, like a trainer in your pocket. It works at home or in the gym, for complete beginners through experienced lifters. Pricing is $9.99/month or $79.99/year with a 14-day free trial on the annual plan, a small fraction of the cost of a human personal trainer.
