Research & Feedback
As someone who uses the metro in Warsaw almost every day, I find the current validation flow frustrating. It takes too many steps and often creates stress, especially at turnstiles or when inspectors appear. After paying, the main reason to open the app is simply to show the QR, so it should be the very first thing users see.
I also researched user reviews in the App Store, Google Play, and on Reddit. Many people expressed the same frustration: the delay between buying a ticket and being able to validate it is too long, which makes the whole process feel stressful and unreliable.
