Prun is an AI-powered running coach app. It generates training plans, tracks workouts, and provides coaching advice using Claude AI.
You can use your own Anthropic API key (free) or purchase credit packs within the app. Credits are non-refundable consumable items. 1 credit ≈ 1,000 AI tokens. Both options provide the same AI coach features.
Training advice provided by the AI coach is for informational purposes only. Always consult a medical professional before starting a new training program.
