Eventually, sure, real software shipped for the Apple II. But in the early days it was all out of house (c.f. Applesoft). It wasn't until the days of ProDOS that Apple got serious about writing its own software, and by then Woz had left and Jobs was working on the Mac.
Really, download an emulator and try this thing. Then download the Red Book from bitsavers.org or wherever and read it. It's a hacker's paradise. It's very much not a precursor to the Mac, or the iPhone.
And it's all Woz. He's one of the greatest hackers ever to live, and yet people like you, trapped in the reality distortion field, have managed to needlessly forget him and/or write him out of the history books. And that makes me sad.
