How do I market my health/fitness app

My app is called Core Health Tracker and I would love some help I will put a debrief below of what my app consists of.

Core is your personal AI-powered health assistant, designed to make everyday health and fitness feel simple.
With Core, you can instantly generate prompt-free, looped walking, running and cycling routes based on your location. Every route can be customised through Core AI, whether you want something scenic, a specific distance, a certain difficulty level, or a route built around your personal preferences.

For extra peace of mind, Safety Mode can prioritise routes designed around safer, more suitable areas and help give users more confidence when heading out. For running and cycling, Pace Coach helps users stay on target during their route by guiding them towards their chosen pace and performance goals in real time.

Food tracking is made easy with multiple ways to log what you eat. Take a photo of your meal, scan a barcode, use your voice, or simply describe your food with AI text logging.

At the centre of the app is Core AI, your personal health assistant. It can create personalised workout and fitness plans, suggest recipes, build custom routes, answer health and fitness questions, and help you stay on track with your goals.

Core also includes a dedicated Apple Watch app, allowing you to start routes directly from your wrist and track your activity data without needing to use your phone.
With Siri integration, you can log food, request routes and interact with Core without even opening the app.
