Over is a popular app used to add text to photos, like captions, quotes, jokes, memes, or poems. Over is now available in a free version called Overgram, with similar but more basic features.
The free version includes 10 fonts, which can be changed and edited before you add it to a photo. Text can be resized, aligned, and repositioned over the image. When a photo is done, you can save it to the iOS camera roll or share it on Facebook, Twitter, Instagram, Tumblr, or email. It also adds a small watermark in the bottom left-hand corner that can be removed with a $0.99 in-app purchase.
Overgram is available for free on the iOS App Store and works on the iPhone and iPod touch. Or, if you feel like spending $0.99 you can get the full version, which is on sale from its regular price of $1.99. With the paid version, it includes extra features like 225 fonts, stock backgrounds, and even more customizations that are not available in the free version.
