ProdDuck is a calm place to keep an eye on your day. Track habits at your pace. Log a drink. Scan a receipt. Tick off what's on your mind. Walk a few more steps. And while you're doing all that, watch a small island fill in around a duck - a tree here, a hot spring there, a frog by the puddle. Bits of a place that's yours, growing because you showed up. One app. Six things you'd otherwise spread across five. No account. No subscription. Your data stays on your phone. Try the basics free, decide later if you want to unlock Pro. WHAT YOU CAN DO • Build habits - set your own pace, choose your own categories, see streaks that never shame you - as a classic list or a calm lily-pad pond that blooms as you show up. Free for five habits; Pro for unlimited plus a library of templates. • Log hydration - water, caffeine, and sugar in a glass you'll actually want to look at. Pro adds custom drink types and Hydration Insights. • Track spending - type or tap it in, categorize on the fly. Pro adds receipt scanning, Spend Insights, CSV export, and unlimited categories. • Manage tasks - a small whiteboard for what's actually on your mind, with categories and due dates. Free for ten; Pro for unlimited. • See your movement - steps and floors that add up quietly in the background, with optional walk sessions. • Grow Duck Island - your routine becomes a small private world. Free for ten elements; Pro for the full island and seasonal events. WHERE YOU'LL USE IT • iPhone - the main calm place • Apple Watch - log water, tick a habit, add an expense, glance at today • Home Screen and Lock Screen widgets - the metrics you actually look at • iCloud sync (opt-in) - syncs to your private iCloud across your Apple devices WHERE YOUR DATA LIVES On your device. iCloud mirror, if you turn it on, goes only to your private iCloud - no third party in the middle. Receipt scans happen locally with Apple's Vision framework; images never leave your phone. No accounts. No bank-sync. No advertising SDKs. No session recording. Short policy, plain English: prodduck.stillraft.com/privacy WHAT PRO UNLOCKS Unlimited habits, the full island, Duck Recaps (your cross-tracker year in review), Spend Insights, Hydration Insights, receipt scanning, CSV export, custom drink types, the template library, and unlimited tasks and categories. BUILT FOR EVERYONE VoiceOver, Dynamic Type, reduced motion. Tested to WCAG 2.2 AA - the same standard government and enterprise apps follow. Tap targets meet Apple's 44pt minimum throughout. PAY ONCE One purchase unlocks Pro. The basics work without it. No subscription. No recurring fee. No auto-renewal three months from now that you forgot about. Made by Still Raft Pty Ltd, a small Australian company. Indie developer and designer. No investors. No analytics dashboards open in another tab. Open the app. Start small. Watch it grow.
