This is a review for the service itself, not the app.
Having traveled globally, Ive seen many takes on public transport services. This is by far the worst.
The first reason being the cost. Its unexpectedly expensive for a bus to... Anywhere. Almost double what Ive seen in most other countries.
The second and worst reason being the timing. The buses dont take too long getting to the destination, but thats only if you can catch one. The buses often run 20 minutes early or late from their scheduled times and are incredible unreliable. My partner, a long time resident of Edinburgh, knows that the schedules and times provided by the website and app are pointless and might as well not exist. In my case, this caused me to miss a fairly important event as on that day, they only came once every hour.
Walk if you possibly can or get a cab. Itll be more money but youll save yourself a huge headache.
