Phone app for software design, specifically the flow and general logic

Question

So I am honestly been struggling to find any sort of phone application that will do what my title describes above. I'm trying to find a way to develop generic software and phone application logic and flow through a mobile device. Trying to do things like have arrows or lines or some way of showing how each page connects to the next. I'm not looking to necessarily fully develop the application or software on my phone.

Answer 1

However, I would like to get up to being able to do images of what I think it should look like along with the generic logic regarding if you press this button then it goes to this screen or if you press this button these are the things that it checks before going to the next screen or window or whatever. Basically almost everything up until the actual true physical code of the software or application.

So what is out there? Every phrase of searching I do I get things talking about apps discussing coding and teaching it or other things other than what I am looking for.

Thanks for the suggestions.

Answer 2

I personally do use a notepad and do OOP and UML. I don't do UML in the sense of what you may know it as, but I do my own version of it.

However, I don't always have my notebook with me or are in a situation where I could write in it if I did. As well, I can't tell you how many times I have had to restart a diagram page because I realized I missed a step in the middle and have to redo the whole diagram in order for it to make sense. This is why I am looking for an app since I could insert these missing steps or new steps and it would adjust everything for me. Less waste of paper and time redrawing.

But I will search for those terms and see what I can come up with.
