Slices lets you bot multiple accounts at once on a device without having to login and logout !!!!!! Recently I found a way to have several accounts on Instagram without having to log in and log out which took time especially if you are managing more than 20 accounts on a single device. This app is called Slices. It only works for jailbroken phones, and it is a free app from Cydia. It's basically an add on to your device. You can operate and macro it with different apps including Instagram, Tumblr, Twitter etc. When you click on your desired app, Slice's menu appears and asks you which duplicated version you want to open. Just wanted to throw this out for people who are botting multiple accounts using a device, because logging in and logging out on a lot of accounts at once is tedious and time consuming. Hope this tool helps!
