I want to provide some feedback on the Jakdojade app, as it relates to tourists.
The app is very good:
- as a journey planner
- including real time transit arrivals and departures
- to see at a glance what types of transit tickets there are
I appreciated having the app for those capabilities as I was using transit regularly to tame the city distances.
For a tourist, I view the app has a shortcoming;
- to buy tickets, you load money into your account
- you can load values of PLN 10, 25, 50 or 100
- transit tickets cost amounts like PLN 3.40 (20 minute ticket) or PLN 36 (72 hour ticket.)
If you load, say, PLN 50 to buy a ticket for PLN 36, you're left with a balance.
This would not be a problem for a resident, but I don't know what process you would follow to redeem a balance after leaving. I didn't want to find out. And perhaps for small residuals, it's not a big deal to let it go. But I don't want to pay that "tax" for my transit.
So I bought my 3 day paper ticket passes at ticket machines for the exact amount, validated them on first boarding, and kept them accessible in case of ticket checks.
There may be apps that allow you to buy with exact value. I did not research this.
