Avoid. Use native Android optimization or reputable Play Store apps instead.

The performance gains are marginal and mostly achievable through Android’s built-in tools (Settings → Storage → Free up space) or legitimate apps like SD Maid (non-mod). The security risks of granting Accessibility permissions to a cracked APK far outweigh the benefit of ad-free ringtones and a fake CPU cooler.

If you simply want to remove ads from the original free version, consider buying the official Pro version (typically $3–$5) to support the developer and keep your device safe. The mod is a shortcut that could cost you much more in privacy or malware recovery.
