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 ($1, $5, $10, $25, $50, $100). 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. If it's your first purchase, a celebration popup shows your First Recharge Bonus.

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.
