Instagram Multiple Account App

[xxGBHxx]

Hi guys. Just wondering if any of you have found any luck with an app for multiple Instagram account management, specifically with being able to upload to different accounts without having to sign out/sign in or use multiple accounts on a phone. iPhones have an app called Instapload which is coming to Android, but sadly not here yet. Just wanted to see if there was anything else out there I might have missed. Thanks!
