This is a great project. Relatively speaking, it wouldn't be hard to make a really basic app that does what you want it to do, in the android studio for example (using java). There are a lot of tutorials out there.

What will be making it difficult is that you will be learning so many things at once, learning java, android studio, and how to work with android all at once in my example. Some may suggest one step at a time. First learn just basic java, then go from there. But I personally think trying to dive in could be a great learning experience if you are patient enough. If it doesn't work out no harm done.

I suggest having some good expectations, though.

Programming is time consuming! However long you think it will take to make whatever you want to make, double it and you'll still take longer (that's my experience as a novice, anyway). Don't expect to be able to tackle this and immediately be done. Look at it like a project, take it slow and take breaks as needed. It may end up being a project that never ends, as you can always improve your product.

You're probably familiar with this since you've coded before.. It may be difficult at times, but don't get discouraged! It's all part of the process and we all go through it. Break the problems down and try to solve problems one at a time. Don't expect it to be easy, the process will come with challenges and I believe it's best to face those challenges in a positive way, as a learning experience. If you can't, it might be break time.

Don't put too much expectation on yourself. Remember you've never made an app before, so don't expect it to be as nice as a professionally done one. You can always pretty it up later.

Most of all, have fun! Good luck with your app.
