I’m doing something similar with a product called Brick. It works wonderfully. I’ve since found all kind of new and interesting ways to waste the time I used to spend on my phone.
I keep my Brick in the laundry room down the hall. The answer to “Do I want to use this app badly enough to walk aaaaalll the way down the hall?” is almost always “no.”
Always. But then again it connects to my constant glucose monitor, and that won’t work if it’s more than about 30 feet away. And since my sugar levels are highly volatile, it’s not a good idea for me to keep it anywhere other than in/at hand.
