User reviews

No network connection

Paid for the app which was initially really good but now app won’t open due to no network connection . Hopefully this will resolve soon ?

Response from developer

This was a temporary back end server issue that was resolved quickly. Apologies for the inconvenience.

Excellent App

This is definitely the only App you need. Regular updates and reminders.

Just takes the hassle out of commuting

Have had this app over a year and it’s been the most reliable source overall to know when the bridge is shut/if there is a queue building. Not sure why there are so many negative reviews as it’s just over a tenner per year which you’d have spent going twice over the Severn bridge back when the tolls were in place! Happy to support a local Chepstow developer and tbh the app speaks for itself. The push notifications are particularly useful. No harm in using the trial and seeing for yourself.

Subscription now needed

Paid for the app roughly 1 month ago and notifications were great but now it’s been updated and requires a subscription even for notifications… seems wrong to have to pay for an app in the first instance and then have to pay subscription for notifications you were receiving before the update

Response from developer

Sorry you’re unhappy. The problem I face is that infrastructure is required to support the service and I’ve been covering that cost for years. In my opinion I’m asking for moderate support to help keep the app going for the benefit of all users. I’m a single developer working on my own trying to make life easier for us all. Thank you for your feedback.

Nope

Bought app a couple days ago for the notification feature, shortly afterwards app is updated and now this becomes subscription “feature”
