I've been using the shopping list in my cell phone for some time now. I find it super practical. But now I'm missing a hand when I'm shopping. Holding the cell phone, pushing the trolley, taking the product, scanning the product... I'd love it if there was a simple cell phone holder on the shopping trolley, even if it's just a "board" with a bar. The scanner can also be adjusted on the trolley and the shopping lists written by hand can be clamped in. So if there was something else for the cell phone, that would be real added value for me 😀
