Why do Apple allow rip-off apps like this? ### 1/5 — Rubbish! *2015-05-25, version V1.0* Don't waste your money.It does not work.It doesn't do anything! I will report this app to Apple who should check what apps they allow on the AppStore. Shame on you Apple for allowing fraudsters on your AppStore ! ### 4/5 — Very Useful *2012-03-09, version V1.0* I'm sure this is a terribly useful app, only problem is that I'm totally unsure if I've entered the congestion zone or not! I like the fact it charts ones movements, but when close to the CZ things become unclear and it's hard to see if a charge has been incurred. Don't know what the entry at the top of the screen signifies. It says a street and 3.9m does that mean the nearest entry point is that distance away or did I stray into the zone!!!!! It looks like a terrific app, but some more info sorely needed. ## Frequently asked questions about London Congestion Charge Alert ### What is the London Congestion Charge Alert app?
