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.
