In Lucky Patcher, I see a custom patch written under an app. What does that mean?

It’s basically like a mod written by someone else and he/she has emailed it to the lucky patcher team. Anyone can create a custom patch, even you and can either send it to LP team and wait till they upload it in their server for everyone to download it or copy the files to the specific directory so you can use them directly on your phone. Custom patches are more usefull since they come with mods which cannot be easily obtained by emulating inapp purchasesor by ads hack, etc. Also most custom patches require root to work.
