Exchange Diet is the smart nutrition tracker built specifically for people managing their diet (an essential tool for people with diabetes). Based on the trusted Food Exchange System — the gold standard recommended by registered dietitians — Exchange Diet makes it simple to stay on track every day. What is the Food Exchange System? The Food Exchange System groups foods by their nutritional profile into 8 categories: Starches, Fruits, Milk, Meat & Substitutes, Fats, Non-Starchy Vegetables, Sweets & Other Carbohydrates, and Combination Foods. By thinking in exchanges rather than counting every calorie, you build sustainable, balanced eating habits that keep blood sugar stable. Personalized to You Exchange Diet calculates your daily nutrition goals based on your personal profile — height, weight, age, activity level, and whether you want to lose, maintain, or gain weight. Using your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE), the app recommends a calorie budget tailored to your body and your goals. Prefer to set your own targets? A fully custom budget mode gives you complete control. Track Every Meal with Ease Log Breakfast, Lunch, Dinner, and Snacks in seconds. Search from a large food database, scan a barcode, or create your own foods.

Every drop you log adds to a lifetime total that never resets. Watch your hydration compound from a single Water Drop into tiers you unlock one surprise at a time — growing with you, forever. Most water apps reset your progress every night. Droply doesn't. Every milliliter you log adds to a single lifetime score that compounds — forever. Watch it climb through tier after tier, each one revealed only when you reach it. Nothing you've built resets. Not ever. THE CORE MECHANIC Tap the drop button to log your default amount. Tap the edit pill to pick a custom volume. 1 ml = 10 droplets. Your lifetime count grows with every sip — and it never goes down. TIERS OF IDENTITY You're not just tracking water. You're building something permanent. Each tier you cross triggers a full-screen celebration and a shareable badge. Reach the Keg — then keep climbing toward the tiers no one's seen yet. STREAK + FREEZE SYSTEM Log water every day to build your streak. Earn a freeze token at every 7-day milestone — one automatically saves your streak when you miss a day. Miss a day without one and the streak resets, but your lifetime total never does. Nothing you've built can be taken away. BUILT DIFFERENTLY · No account. No sign-up. No ads. Ever. · Home and Lock Screen widgets — log a glass without opening the app. · Your progress syncs privately across your own devices through iCloud — nothing ever leaves your Apple account. · No daily reset. Your drops from six months ago still count today. · Particle animations, ambient glow, and a background that shifts from desert to ocean as you climb the tier ladder. SHARE YOUR PROGRESS Every tier you earn generates a shareable card. Post your milestone. Challenge a friend. Water is competitive now. DROPLY PRO — ONE PAYMENT, NO SUBSCRIPTION Unlock everything once and keep it for life: · 3 freeze tokens instead of 1 — triple streak protection · Your daily intake graph — see every trend over time · Custom reminder times — up to 5, set to your day · A supporter badge on your journey No subscription, no recurring charge. Pay once, it's yours forever. PRIVACY Droply collects zero data. No analytics, no trackers, no third-party servers. Your hydration history lives on your device and in your own private iCloud — we never see it, and it's never sold or shared.
