My 2-year-old son thinks all photo frames are digital. He reaches up to the still frames in my parents' house to swipe to the next photo. While in some ways this sounds a little dystopian, I also find myself a little impressed. The Aura frame in my living room, however, has completely convinced my son that it's an analog picture frame. I can't even convince him to take a bath.

Aura's range of digital picture frames is the best out there. The Aura Carver ($149) and Walden ($299) are both top picks in our guide for a reason, thanks to their impressive design and matte screens that don't feel like just an iPad set up to flash photos at you. As of today, there's a new kid on the block: the Aura Aspen.

The Aspen sits right in between the Carver and Walden when it comes to size and price, and it packs the 4:3 ratio that's perfect for smartphone photographers. It's a great addition to the lineup, and if you're usually taking photos with your phone—especially if those photos tend to be vertical—this is the frame for you.

The biggest difference from the rest of Aura's lineup is the size. The Aspen has an 11.8-inch screen—larger than the Carver's 10.1 inches but smaller than the gargantuan 15-inch Walden frame. It packs the same anti-glare display you'll find in the Aspen and Walden, along with a 4:3 ratio and 1,600 x 1,200 HD display. That ratio matches most smartphone cameras, making it a great choice for your daily photos. Otherwise, the software inside is the same you'll find on all of Aura's displays, and you'll use the same app to control it.
