Game Booster 4x Faster Pro

The main screen has a large 'Boost Now' button that you tap before starting a game. It automatically optimizes your phone's performance without requiring any technical knowledge, making loading times faster and reducing lag in games like Gardenscapes and Asphalt 9.

Yes, it has a feature to block notifications and calls for specific games. However, you'll need to grant access to your contacts and phone settings, which some users may find intrusive—you can choose not to allow it, but then the feature won't work.

The app requests permissions like access to contacts and phone settings to block calls and notifications during gaming. If you're uncomfortable, you can skip granting those permissions, but the call-blocking feature won't function. The app still works for basic boosting without them.

There's no built-in way to verify the exact 60% boost, and it's likely marketing language. However, many users notice real improvements in game loading times and reduced lag, especially in graphics-heavy games like Asphalt 9, so the app does provide a tangible benefit even if the exact number isn't measurable.

Unlike iPhone's default settings, which require manual adjustments and don't offer game-specific optimization, Game Booster provides a simple one-tap boost, a temperature monitor to prevent overheating, and a notification blocker for gaming. It's more convenient for non-tech users, but the iPhone's own performance is already strong for everyday tasks.
