JH Digital Solutions was founded by Finnish developer, Jari Huomo, and is the creator of hit Amazon Underground app, Zen: Coloring book for adults. Jari Huomo is an indie developer and self-proclaimed “coffee addict” working out of his home basement to build apps for all ages. After hearing about Amazon Underground on social media, Jari published his app, Zen: Coloring book for adults, to Amazon Underground, and now makes more on Underground than on all other platforms combined.
“My Amazon Underground experience has been superb so far! Zen: Coloring book for adults is now published for Amazon, Mac, Windows 10 desktop, iOS, and Google Play devices. The Amazon Underground version is the most downloaded one and Underground has currently made more money than other platforms combined!”
GETTING INTO AMAZON UNDERGROUND
JH Digital Solutions has adopted a business slogan of “Apps for everyone,” building everything from storybook apps for kids, to tax calculator apps for entrepreneurs. In 2015, what began as a kids coloring app evolved into an adult coloring app with coloring pages created by artists from around the world.
“I actually started creating a kids coloring app at first. But then I saw news in so many places about the big boom of adult coloring and decided to try my luck with adult coloring app.”
Jari has described the process to get his app in Amazon Underground as “Simple,” and his decision to publish to Amazon Underground has paid off, as he has seen over 100,000 downloads and over 3 million minutes played since launch, that’s over 5 years of time spent by customers in the app! With Amazon Underground, Jari is paid for 100% of those minutes played.
“Monetization simplicity is one thing I love. For example, ads require lots of tweaking and testing to find the best ads provider and get the right balance between user experience and money earned. With Amazon Underground only one thing counts, how many minutes the app is being used. So 100% of my focus can be on providing the best user experience possible.”
CONNECTING TO CUSTOMERS
Jari has received numerous positive reviews from customers who love the relaxing nature of his app, but these reviews provide more than positive affirmation. Jari uses Amazon customer reviews as an ongoing feedback loop, and looks at reviews as a tool to continuously improve his app for his customers.
“Amazon customers have been the most active user group to send comments and give feedback which is really helpful for me to make the app better for all the app users.”
Jari continues to reach more and more customers with Zen: Coloring book for adults through his creative social media integration. In a few easy steps, customers can share their works of art from the app straight to their own social media accounts. This helps Jari bring in more customers, and ultimately get paid for every minute they color in Amazon Underground.
MONETIZATION MADE EASY FOR INDIE DEVELOPERS
As an Indie developer, it can be challenging to monetize your apps and games. With Amazon Underground, developers like Jari can reach more customers with the promise of 100% free content, and make money for every minute they play.
“Life of an indie developer can be very different than life of a big app company and my indie developer view is that Amazon Underground is a superb new opportunity to try. App users will surely love it! Who would not love free high quality apps.”
Jari’s success in Amazon Underground has inspired him to publish more apps to Amazon Underground in the future, and he recommends the same for other developers.

WHAT IS AMAZON UNDERGROUND?
