Vignette app allows you to change all those ugly grey circles with initials into actual photographs. By searching Twitter, Facebook, Instagram, and Gravatar—no login required—Vignette will attempt to pair your contacts with their profile pictures on social media. After amassing all these images, using Vignette’s easy to use interface, you can select which avatar you’d like to use, or none at all. Once you’re all set, Vignette will write those updates to your contacts database on your phone. That means in Messages, Phone, and all of your other apps, you see beautiful images instead of ugly initials. Vignette is free to try, but in order to save the updates to your contact list, you will need to buy the one-time in-app purchase. Vignette app runs entirely on your phone; your contacts stay on your device and are never transmitted *anywhere*. Privacy is a critical factor to Vignette; your trust is important and will not be squandered. App Store: Free (Offers In-App Purchases)
