The App Store went live on the 10th of July, 2008.
These are the first 8 apps I installed. It’s noteworthy how many apps from day 1 are still actively maintained today.
What are the first 8 apps you downloaded? In the App Store app, tap your account avatar, then tap “Purchased” to get a list of all apps you’ve downloaded. They’re listed in chronological order, so just scroll to the bottom.
I was but a wee lad with an iPod Touch 1G.
