So here's what it is. Mobile apps require something called a Bundle ID which is kinda a unique way of identifying apps. My apps could have used the identifier "com.saikambampati" but that was too wordy.
So here's another domain I bought to use solely with my apps. Sky High Labs. Plus it's a cool ".app" domain so I impulsively got it. If you're interested in my apps, you can explore them in my personal website. Thanks again!
