I didn't, I don't need another app to track me. A deposit is and should be enough to ensure the return of the item.

I think for many people the proposition "you need to download this app to do something for which the app is not needed" is a non-starter, also for tech-savvy people.

Another thing to consider is that I (and I guess many other people) are only willing to download an app while having wifi, since my data volumne in LTE is limited.

Yeah, totally feel you about the data and downloading the app, that's actually a really good point that I didn't think about! Unfortunately as the boxes are made from food-grade stainless steel, they are worth more than the 2 euros, maximum 5 euros that we would charge as deposit. The risk of people keeping them and losing the 2 euros is fairly high. On the other hand, making it more than 5 euros would deter people from paying, so it's a dilemma at the moment.

Well, the boxes sound really nice – good luck with that:)
