My main objection is that this app is impossible to use without giving it location permissions, and I see no good reason for this when I can e.g. scan the QR code on the PayRange sticker on the machine I'm trying to use. The app is fussy about connecting to the relevant laundry machines - just now it silently failed to pay for one, leaving it unclear that I needed to try paying (via the weird swipe interface) again. And it triggered a fraud alert on my card the first time I tried to add money.
