Show HN: HeartLens – phone-camera blood-pressure and calorie checker

Built a small Flutter app called HeartLens that turns your iPhone into a pocket health kit: take a picture of your blood pressure monitor a BP reading, snap your meal for calories & macros, and quick-log water and weight. Everything syncs to Firestore (and Apple Health if you enable it) so your history’s backed up and shareable across devices. It’s live on the iOS App Store (https://apps.apple.com/us/app/heartlens-bp-tracker/id6747299126 https://apps.apple.com/us/app/heartlens-bp-tracker/id6747299...). Would love feedback—accuracy vs a real cuff, food-detection fails, UI nitpicks, feature requests, anything. Cheers!
