Use Cardvark like a regular app—no app store needed
Open Cardvark in Safari, then tap the Share button (the square with an arrow pointing up)
Scroll down and tap "Add to Home Screen"
Tap "Add" in the top right corner
Open Cardvark in Chrome, then tap the menu (three dots in the top right)
Tap "Add to Home screen" or "Install app"
Tap "Add" or "Install" to confirm
Once installed, Cardvark opens in full-screen mode without browser bars—just like a native app.
