Crond4Android is a powerful Android module that brings Linux-style cron job scheduling to rooted devices, making it possible to automate tasks like backups, cleanups, and system tweaks. It’s mainly designed for advanced users and developers who use KernelSU, APatch, or Magisk.
Most Android users rely on apps for automation, but power users often want deeper control. That’s where Crond4Android comes in. Inspired by the classic Linux cron system, this module lets you schedule commands and scripts to run automatically on your Android device. If you’ve ever wanted your phone to clean cache at midnight, restart a service every morning, or run custom scripts without manual effort, Crond4Android makes it possible.
