While having a ton of friends on Snapchat does wonders to stroke my ego, sending content to all of them at once becomes a hassle when I have to go one by one, checking each contact individually.
Head into the Xposed Installer app to search and download "SnapAll." Alternatively, you can download the mod from the Xposed Repository online.
With the module now downloaded, make sure you activate it, then reboot your device to start using it.
The module will not show as an app in your app drawer, as it just adds the feature directly into the official Snapchat app on your device. When you're ready to share a Snap, just tick the new empty box up at the top of the share screen next to the search icon to select all of your contacts in one tap.
Along with selecting all of your contacts, this mod will also allow you to exceed the recipient limit (200). You can disable selecting "My Story" by entering the SnapAll's preferences from Xposed Installer's modules list.
