Keeping Mobile Gamers Engaged with App Widgets

Posted on October 2, 2023October 6, 2024 by James O'Claire

I love using widgets. I probably have too many of them on my phone’s home screen. News apps, weather apps, stocks, stats. I love being able to glance through them without opening the corresponding apps. This led me to realize though that I have seen very few widgets for mobile games. As I started working…

I built my own very simple strategy game

Posted on September 24, 2023October 6, 2024 by James O'Claire

It certainly isn’t anything amazing, but it was something that I really wanted to do for myself. After recently stepping away from my position at Bubbleye and taking a month or two to enjoy some camping, family time and generally enjoying life I finally got back to Taipei and realized I had a unique opportunity…

Is Someone Else Using Your Game’s Monetization IDs?

Posted on October 31, 2022October 6, 2024 by James O'Claire

Looking around app-ads.txt files one of the first things I was excited to check was whether DIRECT publisher IDs show up on other unrelated apps. To do this I ignored any apps that shared the same developer contact URL or Developer IDs. This doesn’t catch 100% of the legitimate publishers I checked, as the examples…

What A Mobile Ad Monopoly Looks Like

Posted on October 12, 2022October 6, 2024 by James O'Claire

Google’s market share in in-app advertising is unmistakably dominant. The data above was scraped from 100k+ Google Play Store & Apple App Store apps (with a slight emphasis on games) who use advertising for monetization.

For decades, science fiction and technology visionaries foresaw a future where consumers were able to freely traverse virtual reality like surfing the web. Virtual reality was seen as an open platform where millions of people could share, consume and explore content. Instead of…

To Love & Hate in the World of Advertising

Posted on April 2, 2016October 6, 2024 by James O'Claire

“I hate ads, who likes to see ads?” Recently my mother came to visit me in Taipei. On the drive from the airport we talked about my startup, Bubbleye, and how we predict a user’s interests in mobile ads. Her response: “I hate ads, who wants to see ads?” She’s right, no one wants to see…
