Great idea kevin, I'll take a further look at the code when I'm not on my mobile.

A couple of quick pieces of feedback, images are always great to show off the apps, if you have multiple screens you can also use a gif (https://ezgif.com/maker)

Another idea since you're happy to share the code is to put it up on GitHub (https://github.com/)
Do you use any source control / version control systems? It's a great habit to get into.
Plus you can add up releases and keep track of versions etc, also others can provide feedback, raise feature requests or bugs and even help add them to the app.

Cheers Alex, I'll look in to it, but at the moment I have no idea about any of that. Always happy to learn though.

I'll definitely take a look through some of them when I have some free time. Thanks for sharing.
