Switching back and forth between Instagram accounts is a HUGE pain in the butt. My first thought was that we should file this issue under #WorkingGirlProblems (people who post for themselves and their small business or clients). Then it occurred to me, the ability to motor multiple accounts would be useful for parents with young children. When you follow your kids you can see what they post but not who they follow. With this app, you can jump to their account and see the feed of images they are viewing posted by other people.
Whatever your need to switch, you can now do it with “Repost for Instagram,” not to be confused with InstaRepost or many other competitors. Hallelujah!
To my knowledge, Repost is the only app that allows you make the switch without having to log in and out.
Red Cactus, the company that produces this app, also makes a few others that I like: InstaQuote and PicFlow.
