I have an old Macbook Air if I need it but I absolutely rarely turn it on. I would like to make a very simple blog that I can post an image with a story a few times a week. I don’t need any other parts of a website, maybe just an about me page or something.
Do I need a computer to do any of this? I saw there’s an app on the app store for WordPress when I searched for websites in the app store and when I go to the website it seems like it will all work but I thought I would ask the experts.
Is this a good enough place to start for free?
It’s technically possible (at least on Android), but I wouldn’t recommend it at all. It will require decent knowledge of Linux and root access on your phone to even get a webserver & mySQL installed, and even if you succeed it’s likely that your phone carrier will not allow any incoming connections on ports 80 or 443 (HTTP / HTTPS)
Are you asking if you can maintain/edit/update a website exclusively from your phone or do you mean to ask if it’s possible to use your phone as a web server for hosting your website?
If you want to just make posts, yeah, probably. Assuming it’s all setup. If you are starting from scratch, that’s a different story.
