Developer Spotlight: Zen Labs Fitness

Kiip works with thousands of developers, so it only makes sense for us to interview the masterminds behind the apps we integrate into. In this Q&A we meet Bradley Duong, the co-founder of Zen Labs Fitness and the popular app C25K (Couch to 5k). Check out Bradley’s responses below about the lessons he’s learned while developing and monetizing his app.


Tell me about yourself and your role at Zen Labs Fitness.
I am the co-founder of Zen Labs Fitness. My business partner and I have a deep passion for fitness, wellness, and technology. We’ve been fortunate enough to successfully tie these together to create simple and intuitive apps tailored for people new to fitness. Our programs provide encouragement that increases user retention and allows more beginners to finish their programs. More people finishing what they are starting.

How big is your development team?
Our dev team is comprised of 10 highly talented individuals, specializing in both iOS and Android development.

What tools help you work?
For my role, it’s all about being organized, and having access to my files/data where ever I am. So two big tools that I use everyday is Basecamp and Dropbox

What’s the most important lesson you’ve learned when building a mobile app?
It’s all about keeping the app as simple and user-friendly as possible! You can have all the features in the world, but if users don’t know how to use your app, you’ll have an extremely hard time getting the app off the ground.

Any advice for developers creating their first app?04
Focus on quality. There are many factors that go into developing and launching a successful app, for example marketing and app store optimization. But the most important thing you can do to help yourself is to have a well-functioning, user-friendly app. Without a solid app, the rest is pointless.

Tell me about your experience with mobile monetization. What works, what doesn’t?
This is very dependent on what type of app you have. In our case, with our fitness apps, in general, we like to offer most of our apps for free. Our users get the entire program for free, and we have features that they can upgrade to, but the features are not necessary to enjoy the app. Build a good app first, and after earning the users trust, they will be more willing to pay to upgrade.

What do you like about moment-based rewards and Kiip?
Kiip has been really popular with our users, as after a long hard workout, the kiip rewards is like a real life reward for exercising.

What’s next for Zen Labs?
Continue to fill out our suite of fitness apps, and hope to become a one-stop shop for all things fitness, no matter what the goal is!
