Step 1: Tap Me tab at the bottom → Wallet. Step 2: Tap the purple "Recharge" button next to your Vio-Gems balance. Step 3: A list of coin packs appears ($0.99, $4.99, $9.99, $19.99, $49.99, $99.99, etc.). Bigger packs give more bonus gems. Step 4: Tap your chosen pack — the official in-app purchase sheet opens. Step 5: Confirm with fingerprint, Face ID, or your store password. Step 6: Coins land in your wallet within 10-30 seconds. A celebration popup shows the bonus items if it's your first recharge.

Tip: if the purchase sheet does not appear, make sure the store app is installed and you are signed in with a valid account. Restart the app and try again.
