Siply | Hydration and Water Tracker With Beverage Library, Charts, Reminders and Paywall - SwiftUI

Demo Instructions

Siply is a fully offline app. There is no login and no demo credentials. Open the project in Xcode and press Run: the 3-page onboarding starts immediately. Complete it and you land on the Today screen – tap any beverage card to log a drink and watch the animated wave fill the drop.

The Premium subscription uses StoreKit 2 with placeholder product IDs (siply_y and siply_m). Without App Store Connect products configured, the paywall still renders with fallback pricing and the free tier stays fully usable. No configuration is required to run the demo.
