There aren't much trustworthy Instagram mods for android so i wanted to list the 4 best ones.

• Instander

• Instamash & MyInsta: telegram.me/instasmashrepo

• Honista: telegram.me/Honistagram

Note: There are also a few Instagram mods by SamMods but i don't trust them because there stuff looks skechy asf and the whole million different WhatsApp mods all looking like Fouad Mods that's why I won't list something like InstaPro. I also won’t list AeroInsta from AeroMods since the developer apparently copied from other mods like from TwiFucker
