I have about 25. Pretty much mirrored on both my iPhone and iPad. All of my banks, several travel associated hotel booking and transport maps and timetables, and the Grindr types - although I haven't used the Gay "social media" Apps in a long while.

I tried the Handwriting Apps, for times when it is more fun to handwrite with one hand than type with one or two, but they are too primitive. I have a couple of music instruction Apps, but the screen is too small for my fingers.

I also have the 3 Apps I have written! They are Map Apps, as described in another thread. Views of my address books in Map form. That now also involves my Google Android phone. Map Apps are more convenient to use and maintain than html pages.

I have Apple (iOS), and Amazon and Google (Android) Developer accounts, and today I am opening my service bureau Developer account, so I can provide App consulting, development and hosting services to others.

My little corner of the Adult Entertainment Industry provides for a basic living. I want to diversify my time and income a bit, by spending a few hours a day doing computer programming in the form of App development. I'm pretty good at PHP, but PHP is pretty common to learn, but also involves data tables which is not always easy for a 3rd party to get involved with... and I like doing forms, but html forms are pretty common. Apps so far, are similar to, but different enough from, PHP and html, that there's a bit more of a want and need.
