★★★★★ One of the nicest public transport app I've used. Just a bit slow to purchase tickets, but maybe that's the international card check, no idea.

★★★★★ Nighttime, needed a ticket fast. Install, register card, was on the bus 6 minutes later with a valid ticket. Good stuff.

★★★★★ Perfect, very easy to buy tickets. Just have it on your phone. I think you don't really need to scan, except if the driver or inspector ask for it.

★★★★★ Useful application for who don't speak Hungarian!

★★☆☆☆ The worst transit app I have ever used, it's honestly better to avoid even trying. Tourists: Use the machines, buy day passes instead of singles. You'll be better off. The worst part is having to register twice with your address and billing information like you are buying a house. They want WAY too much information just to use the app. The ticket machines ask for none of this, just cash or card, and it takes apically less time to have a ticket in hand and ready to go. Avoid this.

★★☆☆☆ Sometimes it is unavailable, always forget my ID card number, especially when I don't have time

★★☆☆☆ It is awful, that if you are in any other menu of the application, e.g. route planning, then it is slow and difficult to get back to the ticket validation. So far I missed two buses because of that.

★★☆☆☆ Forget it, better go buy a real ticket, these people will still find a way to fine you if you even buy virtual tickets. Just sayin' 😕
