There are very few companies that continue to impress me, but Algoriddim has done it time and again. It’s not only the products, but the attitude in building those products to be great that wins me over.

Algoriddim is well-known for making djay for iPhone and iPad. It’s a DJ app that caught the attention of first-timers and professional DJs from around the world. Late last year, the company took the lessons it learned from building the mobile app and built a version for the Mac.

djay Pro for Mac is very similar in appearance to its iOS counterpart, but this is definitely a pro app. It includes 64-bit processing, multi-core track analysis, support for Retina and 5K displays, graphics rendering at 60 frames per second, and of course, incredible sound quality.

Algoriddim was able to avoid the main pitfall that plagues many companies when they bring a pro app to market—complexity. Far too often I see pro apps that are so convoluted that it makes you want to pull your hair out trying to figure out how they work. That’s not a good experience, whether it’s a pro app or not.

I spoke with Karim Morsy, CEO of Algoriddim, last month and he outlined his philosophy for building djay Pro for Mac.

“Pro doesn’t mean complex, it means flexible,” said Morsy.

Exactly right.

djay Pro for Mac is all about layers. Not necessarily layers of complexity, but rather layers of increasingly fine options. This is what makes the so app accessible.

As a user, you want an app that you can grow with as you become more experienced. You don’t want to feel like you’re being held back because you don’t have all the features needed to get the job done. Balancing that with not overwhelming people with too many features is tough, but Morsy and his team did it.

There are a lot of companies out there that could learn a lot about building pro apps from Algoriddim and their approach to djay Pro for Mac. At $49 on the Mac App Store, it’s underpriced for what you get.
