Time for an introduction!

Arthur, 29 yo

I’ve been building products since 2013, starting in e-commerce. In 2016, I started working in fintech as a software engineer, and I’m still in the industry today - combining my full-time work with building my own products on the side.

I’m delighted that my new app was sent for review yesterday, but unfortunately, the App Store Connect is down today.

Apple status page confirms outage of App Store Connect.

[Arthur @arthurdevlab]

The biggest surprise from @Apple: App Store Connect is down for the last hour.

And in January 2026, I launched my next product: @countdownxapp

It’s iOS app that counts down days until (or after) important life moments and provides native widgets and reminders.
