AimiRun is a free mobile application that functions as an artificial intelligence running coach. Its primary purpose is to help users create structured running plans, receive live voice guidance during workouts, and review their performance after each run. The app is designed for runners of all levels, from beginners to those returning to the sport, and does not require any prior knowledge of training terminology. Users interact with the AI coach through a chat interface to set goals, adjust schedules, and receive feedback. The application offers several core features. Users can generate personalized training plans by describing their goal and available time in a conversational manner. The AI coach can modify plans in response to schedule changes, such as moving a workout to a different day. During a run, the app provides live voice cues for pace, rhythm, and cadence, offering guidance only when it can help the user find a natural stride. After each run, the AI delivers practical feedback and suggests next steps. A smart cadence feature analyzes the user’s cadence, pace, workout type, and target, then provides cues only when beneficial. Users can also record voice notes during or after a run for later review. Typical use cases include starting a running habit with a run walk program, training for a specific distance like a 5K, or incorporating interval, tempo, recovery, and long run workouts into a weekly schedule. The workflow involves chatting with the AI to define a goal, receiving a plan, following live guidance during each run, and reviewing the session afterward. The app is built to handle real life adjustments, such as shifting workouts due to other commitments, and it recalculates the plan accordingly. AimiRun is available as a mobile app and requires only a phone to operate. It contains no advertisements, paid courses, or subscription fees for its core running features. The app is intended to keep the entire running routine in one place, from planning to execution to review.
