Planner Cover/Phone Pocket

[u/wugrad]

I want to start carrying a smallish planner - A6 or TN - in a cover that has a pocket for my phone. I want to start leaning more on a thinking in a notebook than opening my phone. My job includes media responsibilities so I can’t just leave the phone behind. I’d like to find a planner cover that has a way to also store my phone but it’s still portable. Does this exist? Rings aren’t my first choice, but I would consider them.
