really simple recording app for memos etc

Hi all,
I wonder if people might be able to give me really simple recommendations for a voice recording app for ios, the sort of thing you might use for notes, memos reminders, lists etc.
This isn't for me, its for someone who I know who is in her 70s, and has made very good progress with using the iPhone, but she needs a lot of training and repeating of steps to get comfortable with doing things on her iPhone.
she uses a parrot for recording things like shopping lists phone numbers etc, but I said I would see if I could find out about something really simple for her for the iPhone, she has already tried the built in Voice memos app and really didn't get on with it.
really she needs something as simple as possible with no fancy bells and whistles something as basic as possible.
I wonder if I could get recommendations please? I will also have a look myself on applevis but thoughts would be appreciated as I can't test all the recording apps out there, and being younger I am used to more advanced apps.
