I built the Android app in 2013, and my best selling web app in 2021. The web app has just gotten beyond the $10,000 USD monthly recurring revenue metric.
Looked up your submission history and found your site pretty quickly. Bravo, my friend - you created a service I didn't even know people needed and you're completely rocking it. Great job!
Is your app something always used online? Is there a way to use the web app offline for those who are away from internet access but still want the functionality?
No it requires an internet connection to use my app. I could make an offline version, but it's not something many users are asking for.
