Panotronic

End the frustration of posting panoramic photos on Instagram® with Panotronic. Panotronic splits a selected panoramic photo into a set of square images, or it can create a movie that pans across the panorama. The share extension allows you to copy photos from most apps to Panotronic.
Note: Instagram does not yet offer a way to automate multiple photo posts, so you will need to open Instagram and tap the multiple-photo button and select the saved photos from the camera roll in Instagram. The resulting multi-photo post will allow you to swipe seamlessly across the panorama.
