Can you please recommend an ANDROID CAD app?

Good morning.

My request is a simple one, I think.

Please can someone recommend an Android(s) App that will enable me to do the following:

I would like to be able to create basic BLUEPRINT / CAD type files on my Android (Samsung Galaxy S9) phone.
I will attach an image below to illustrate just what I'm referring to.

Due to a long term illness, I am in hospital alot so would like to basically just tinker away on an image.
I am new to CAD and only do this for my own enjoyment so a costly App would be overkill.
