I don't have the app (I should get it ....), but I use the notepad feature on my iPhone. I just type it there. It looks like I'm texting or just playing with my phone.
Despite what people might say here, you need a smart phone to be efficient and productive now in MS.
Thanks everyone for the suggestions. While I try to rely on memory, I typically do these shops with my 3 year old so I appreciate the memory jog certain apps can supply.
When performing grocery shops and fast-casual restaurants, I use a digital watch for timings and screen shot my entry and exit times. This has been helpful but there are more timings in my latest shops and I dont want to lose my pay because I forgot/lost/missed a timing.
I have also had some shops require that I only use my phone, not paper at all. I can't record in my state.
I found the shop-it app quite helpful!!
