NexRex: AI Running Assistant

New in this release: • Water & Weight Tracking — a new Health section on your home screen. Quick-add water against a daily goal, log weigh-ins with body fat, and see your trends and history at a glance. You can now edit or delete any weigh-in. • Recovery Tracking — an interactive body map: tap where you're sore, set the severity, and log the recovery work you did. • Recovery Analytics — soreness trends, a body heatmap of problem areas, and your recovery volume over time. • Apple Watch — log water, weigh-ins, and recovery check-ins from your wrist, plus a hydration watch-face complication. • Race Celebration — finish a race and get a moment to celebrate it. Plus stability fixes across training plans, recovery, and the home screen.
