Terrible! Do not recommend. My ride should've been ~20 min. About 5 min in, it quit working. Idk why. There's no way to see your trip before going, so if I went through a restricted area,I had no way of knowing that would've been a problem before starting. Also, I wasn't even "rolling" the scooter, but actively had to push against resistance in the tires to make it move. For 45 minutes until I got to a parking spot. I don't even have a way to request a refund because their chat is broken.

I used the app in Vienna. Everything was fine- I bought a pass, I used it once. But then the map in the app malfunctioned. It shows only a blue screen, and doesn't show any scooter locations. I cleared cache, data, uninstalled/reinstalled... nothing works. So I can't use the remainder of my pass. Also, btw, these scooters are way heavier than any of their competitors. If you want to lift it from the street to the sidewalk, forget it.

Updating my review: Payments no longer work. Tried Multiple cards from different banks AND Google pay. Nothing works anymore and now I can't rent a scooter at all Good parking, ride, and pricing, but the way it calculates minutes is terrible. It will always round up even if you're 1 second over. I literally had a ride that was 8:01 and it charged me for 9 minutes.

The app is always buggy when you needed the most. Unable to ride after booking the bike multiple times. When you pressed start, you'll automatically get charged. Regardless if you're able to ride them. When you cancel right away, you'll still get charged, even though you end up didnt ride the bike. Less than two weeks and at least three failed attempts already. Lastly and most frustatingly, there's no refund button for this failed attempt. Just install other competitor apps.

Having access to scooters is nice when I'm running late, but the minuses of the app limit me using it as often as I'd want to. Ending a ride always takes an extra minute or two, which you get charged for. Sometimes I scan a scooter and it turns out to be broken, despite me only moving a meter and parking it back in the same space, I get charged for the unlock fee, plus 1-2 minues the app spends ending the "ride".

The updated app is nicer looking than the old but many features are gone. For example I can no longer access settings, prices or ride history. There is now a grayed out icon, which, upon pressing informs the user that this 'feature is coming soon'. If you are going to release an unfinished product inform the user first and let them opt into an alpha/beta rather than forcing them to update. Also, it is illegal in Sweden to not show prices for your services.
