A high-performance VPN built natively for iOS. Lumio VPN encrypts your internet traffic, shields your identity from trackers, and ensures your browsing remains entirely private — whether you're on home Wi-Fi or a public hotspot.
Lumio Cleaner
Clean. Fast. Optimized.
Lumio Cleaner gives your iPhone a fresh start. It intelligently identifies redundant files, duplicate photos, and junk data that slow your device down — then removes them safely, freeing up precious storage and boosting overall performance.
