All other parking apps, you select the time, you pay. I selected the duration, went to pay, amount was “£0”. Thinking it was my mistake I tried a different payment method, same thing. Then I noticed it was a pay on exit thing. Ok, so I assumed after my chosen duration expired the payment would go out. So I did my meeting, finished a bit early, back in the car, drove home and THEN received a notification to say my time was running out, did I want to extend? Most other apps, because you’ve paid, you can ignore the notification if you’ve already left and don’t need to extend. BUT I suddenly twigged I had to MANUALLY END the parking session IN THE APP, and THEN the payment went. If I’d ignored the notification because I was already home, didn’t need an extension and not opened the app again, goodness knows how much I would’ve been charged - probably received a fine, like many others. Horrendous! There was NO indication that the app worked like that, and NO reminders on the exit gates of the car park. I had no choice in using this app and this car park, but if you can, AVOID!! One star because I can’t put zero.

I recently had a quite awful experience with this app during a visit to a hospital car park. By mistake, I initiated a parking session via the app without realising that the car park operated on a pay-on-exit system. After discovering the mistake, I paid for my parking at an exit machine because it was simpler, thinking the issue was resolved. However, the app still had my session running, which led to it charging me for 12 hours of parking that I never used, even though ANPR would have clocked me leaving against the session I already paid for. This is a possibly purposeful oversight in the app's functionality, causing unnecessary stress and cost. It needs a clearer indication of parking rules per location to prevent such issues. They also seem to not have a link the the existing ANPR system used in the car park, so are ignoring entrance and exit times. As it stands, I ended up paying six times more for parking than I should have… Resolving this with customer support is a no go. I’d avoid this app at all costs, unless you want to be inadvertently overcharged. Crooks

Sippi is, without a doubt, the worst parking application I’ve ever used. The app itself is a mess. It looks like it was designed by a student learning programming, with a clunky, outdated interface that’s painful to navigate. But the real kicker is its functionality (or lack thereof). It can’t even handle basic residential parking, forcing me to use their website instead. What’s the point of an app if it doesn’t work for its core purpose? And don’t even get me started on their support team. While I’ve never contacted them about the app itself (because, frankly, it’s beyond repair), I’ve had to deal with them for other issues, and they were completely useless. They offer no real solutions, just empty responses that leave you more frustrated than before. On top of all this, Sippi seems to prioritize one thing: charging exorbitant prices. They set their rates as high as possible without providing any value or reliability in return. Do yourself a favor and avoid Sippi at all costs. There are far better parking solutions out there, this one is a waste of time, money, and energy.

Like countless other people, I downloaded the app, entered the location, entered by car reg, entered the payment details, paid for my parking session only to receive a PCN within a couple of days. No record of my session, no payment taken. I have a distinct memory of following every instruction to the letter and even looking at the confirmation page with all of the details! I have now appealed and have accused them of fraud. They are aware of this being an issue, have not fixed it and are continuing to fine people who genuinely thought that they’d paid for their parking. I will never use the is app again.
