Used CreditKarma to file my taxes the last few years and was pleased with that service. Tried to file today and was redirected to a QR code to this app. Why on earth would I want to file my taxes on a mobile phone?? I'm under 30 and work in tech and I STILL think this is the stupidest UX. It's decidedly not for me. I'll use a different tax service, thanks. Edit: the developer's comment misses the point of my complaint. I should *not have to* install the app go file my taxes on PC.
