iTab is an app for people who do not want to put the official Instagram app on their menu bar. This app allows you to access Instagram via an insta-tab that sticks to the edge of your screen.

See your profile and other people's Instagram images

iTab gives you quick access to Instagram. It will not notify you about interesting new images unless you pay for the Pro version, but it does allow you quick access to Instagram where you may look at your pictures and other people's pictures. Being stuck to the edge of your screen makes it very quick and easy to access, but it may bother people who do not check or use Instagram on a daily basis.

A little misleading with regards to functionality

iTab offers quite a few social media functions relating to Instagram, but most of them are with the paid Pro version. The free version feels more like a taster and pales into comparison with the pro version. Yet, the developers frequently promote the paid version’s functions on the pages where people download their free version. Some people are then disappointed to find that the free version doesn't do all the things that were promoted such as desktop mode, stealth mode, pop-up notifications, and full-screen mode.
