How many times have you stopped on a friend's Instagram photo and wished you could zoom in? Using a simple iOS feature, the folks at OSXDaily reminded us [1] that it actually can be done. Here's the deal: on your phone's Settings app, click on "General" and then hit "Accessibility." Find the zoom setting and turn it on. Open Instagram, and, using three fingers, double tap a photo to zoom in.

Easy, no? If you swipe up with the three fingers, you can zoom in further; swipe down and you'll zoom out. You can also move around the photo using three fingers.

Now you can inspect all those awesome Instagram hashtags [2] even further. Even better, use the feature on other zoom-less apps like Vine and Youtube. Magic!
