Can I also park without a time limit?

Yes, that's possible. In the screen where you choose the end time you will find the button 'Without end time'. This feature only works if you have enough credit, as reservations are made 24 hours in advance, so your credit must be enough for 24 hours of parking or a day pass. You will see the following in the screen above the 'Pay' button: 'With parking without end time' you park for the maximum parking duration of up to 24 hours. When you manually stop parking, the amount is adjusted to the parked time. This way you can check what a whole day or forgetting to cancel will cost.
