It's super easy, it works perfectly with my android device (Samsung Galaxy S7). The app is very intuitive and straight forward for all users without any issues or problems at this point in time so far. We have used other apps before but they were not as user friendly nor did we find them that convenient. So I think that has changed now since using cellopark! Parking tickets are easily created from our vehicle and then paid through the application itself which makes life easier during busy times of day when you need your car most. It is easy to use and convenient for both customer and driver. I like that it is integrated with my debit card so I don't have to carry cash around. The app is sometimes buggy and not always up to date, but overall it works well. The best part of cellopark is being able to pay before you park and getting out of your car without having to worry about carrying money or coins.
