Blackjack Strategy+'s latest version is now available on the App Store.
This is the third release in what's become a series of semi-annual updates. In version 4.0, I finally introduced Universal App support thanks to advances in Adaptivity. In 5.0, iOS 13 Dark Mode is the big-ticket feature. I also changed the name - the app is no longer known as "Blackjack Strategizer". I don't think people enter Bushisms into App Store search.
A tip for other developers out there: r/TestFlight is a great place to recruit beta testers. About 60 people accepted the public TestFlight link there, and 75% of that group actually installed the app. I got some good feedback, which was crucial since I wasn't quite sure if the Dark Mode design was useful or even good.
