Tutorial/skill level required/already existing app? - pop-up texts at set time frequency
So, I want an app where I store different texts, which then later pops up when I want, like every 24hr or every morning. I would like to make this app myself because I want it simple and to understand it completely.
I am not new to programming, but I don't know this language. Do you think this would be hard for me, to create this app, but with "full guidance", or is it better to leave it to someone who will create it for me, or maybe there is an already existing simple app like this one.
