Everalbum is a quietly successful photo app that's trying to take on Google and Dropbox

Everalbum cofounder Andrew Dudum says the average person doesn't understand anything about gigabytes or megabytes, or how many photos they actually have on their phone.

And when Dudum set out to build a photo management app, he felt this fact was something the established apps completely ignored.

Dudum describes his particular market as being split into two sections. Either the app is just a utility, a box you throw all your photos into so you don't lose them, or it's designed for the tech community, and is inaccessible to the average consumer.

With Everalbum, Dudum wanted to make an app that was an intuitive mix of "backing up" and sharing with your friends. This approach has helped Everalbum quietly build a following around the world, with rapid growth in the past six months.

The app currently sits at number 11 in US downloads for productivity apps on iOS, and is the highest-grossing app in that category (partially due to its premium tier being structured as an in-app purchase), according to App Annie. And Everalbum's team claim to have backed up more photos in the last 90 days than competitors like Google Photos, Microsoft's OneDrive, and Flickr. This is one way to measure momentum in the space.

But if you've never heard of Everalbum, that's probably because of the team's development strategy.

For the past year and a half, they have been building Everalbum under the radar. Dudum says they decided not to put any resources into marketing early on, or building buzz, and instead focus on the product side. They raised a small seed round, just enough to hire a team of 20, and then went heads down.

"If you have a small team that is really focused you can build something huge today," Dudum says, especially in the app space. They didn't need to raise a bunch of capital to do what they set out to.

The Everalbum app starts from one core feature: unlimited photo backups for its free tier (in "high" resolution, though not "full" resolution, which requires the premium tier). The app brings content together from a bunch of different sources, from your camera roll to your social media accounts. It then lets you turn those photos into things like collaborative albums (think a wedding).

Dudum wanted to build an app anyone could understand, and he's proud that his user demographics seem to be spread evenly, not skewing toward one particular group. This same thinking extends to Everalbum's international strategy, which has been a focus from the start. The app is available in 15 languages.

And now Everalbum has released a full redesign of the app aimed at making it faster and even easier to use.

You can check out the app for yourself at the App Store.
