Can a person write their own apps?

No. You can’t write an app with no programming knowledge. What do you mean when you say “app”? Are you interested in developing a mobile app, some kind of service, or a website of kind? If it’s just a website, you might be able to get away with just setting up a Wordpress blog.

Well, yes, that’s how almost everyone does it but it depends on what kind.

I had a mobile app in mind.
@hominid I have the idea but not sure how to lay it out yet. I know it sounds a bit crazy but it will help with our marketing.

A native mobile app would be difficult without programming knowledge. But theoretically, if this app idea ends up just being a means to provide marketing content, then you still might be ok with using Wordpress with a decent responsive theme so people can access it on their phone/tablet.

I think a mobile website would work better than an OS specific app, it would work on multiple devices more easily web page coding is easier than something like XCODE

@hominid that sound like an idea. @XOIIO by referring to a mobile website is it something like Twitter?

@antimatter Yup, there is basically an easy way to take a standard website and spit it out in a different form and simple throw “m” or “mobile” in the url, you could also make it exclusively for mobile devices. Fluther had one for a while actually but I don’t think it’s around anymore.

I’m guessing wordpress has an option to make a mobile site. Never really looked into it. You will need to pay for domain hosting but it is cheaper than an apple developer license anyways.

I think google BlogSpot has one too but I don’t know for sure. Also, that would give a less “professional” url, one where you have to have .BlogSpot.com at the end.

@antimatter – And just to be clear about the Wordpress idea – I have known a few people lacking programming or web development skills who needed a website. Wordpress has worked out for them because:
– It’s usually available as a one-click install on most inexpensive web hosts.
– It’s a mature product and there are many theme/template designers out there.
– You don’t need any programming knowledge.

Or, if you’re interested in learning some basics, you could get up to speed fairly quickly on HTML/CSS without too many headaches. It might be fun, if you’re into the whole challenge.

Here’s a mobile site thingamajig for wordpess.

You can but if you have never programmed or don’t have a lot of time I would not recommend it. Mobile apps are some of the easiest though. The sdk and programming environment are free for android. It’s programmed in Java. A good bit of code is canned and there are excellent libraries and templates available. Ios is a little harder. The sdk is not free and it uses objective c. C is generally regarded as more difficult because it uses pointers a lot.

Adobe Muse allows you to design a website and then package it as an app without using any code.

I agree with Hominid. Starting with a responsive website is a great first step.
But you’ll need to know how to code HTML, CSS first.

Once complete you can make an APP that runs using your responsive site as an APP.

Yes you can, I suggest that you do some research on the internet and decide which creator you want to use.
