There are few apps more synonymous with the iPhone than Instagram. It was one of the earliest defining apps on the smartphone, with an ascent made hand-in-hand with Apple's App Store. Which is why, through another lens, it's absurd that over 15 years, Instagram never launched a dedicated iPad app. Instead, its loyalists have been stuck with a tiny version of the iPhone app running on their iPad screens. That is until today: Instagram is now rolling out its first official iPad app.
