Android runtime (ART) is the managed runtime used by apps and some system services on Android. ART and its predecessor Dalvik were originally created specifically for the Android project. ART as the runtime executes the Dalvik executable (DEX) format and DEX bytecode specification.

"Hexatune adjusts several Android Runtime modes to modify application behavior during the first launch, making it more optimized and aggressive. Each mode in Hexatune's features requires a considerable amount of time depending on the number of applications installed on your device."

"Hexatune requires Shizuku permissions to run its features. Please activate and connect the Hexatune app with the Shizuku app before using its features."
