Every weight app shows you a number. RESERVE shows you your position — exactly how close you are to the next pound coming off, closing in real time. Not "you weigh 184." You're about 2,500 kcal from the next pound down, a few days out at your pace. That distance is the whole point: a finish line you can watch yourself reach, instead of a number that just sits there. HOW IT WORKS • A living orb shows your metabolism at a glance — it fills when you eat and drains as you burn, so you can watch your body flip from burning food to burning fat. • The ring around the orb IS the pound you're on. As your body oxidizes fat, it drains — you literally see the gap to the next pound close. • A hero bar shows how far through the current pound you are, and it moves the moment you log a deficit or a workout. BUILT BY A PHYSICIAN, HONEST BY DESIGN • It learns your REAL daily burn from your own data — not a textbook formula's guess. • When the scale jumps up, it stays quiet. Early-morning weight is mostly water, and a doctor wouldn't scold you for it — so the app doesn't either. • After time away, it tells you what it didn't see instead of inventing numbers. YOURS ALONE • 100% on-device — no account, no server, no ads. Your data can't leave your phone. • One-tap export of everything you own. • Charts you can HEAR (Apple Audio Graphs) for blind and low-vision users. • A pregnancy mode that hides the scale entirely and talks about the week ahead. Free. Built solo, over a year, by a San Diego physician. RESERVE is a motivational tool, not a medical device. ## Key features - Real-time metabolic visualization - Progress towards next pound loss - Personalized daily burn calculation - Water weight fluctuation handling - 100% on-device data storage - Audio graphs for accessibility ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/reserve-metabolic-hud/id6772624785/reviews.md ### 5/5 — Easy to use; lots of features *2026-07-05* I have used several food trackers but I really enjoy using this one.
