It simply does not work ### 1/5 — Poor *2019-10-26* Latency means the speed indicated is several seconds out from reality. Annoying “try our other products” appears every time you start driving. Don’t bother. ### 1/5 — Rubbish *2019-07-07* Running on iPhone 8 Let’s be realistic the only reason you would want this app is to stop you getting speeding tickets therefore all you really need to know is when you go over the statutory speed limit i.e. 30,40 and 70. I would like the app to tell me when I am just under speed limit. You have to reset to 0 mph over limit every time you switch on and no indication on the screen as to whether you have been successful. On the screen it shows Km/h in the centre when graphics are in mph. To be honest some of the free speed checkers are far more affective don’t waste your money. ### 1/5 — Very poor. *2019-04-29* I downloaded this only to find it doesn’t work on the iPhone XS. The speedo is stretched and unreadable. How do I get my money back? ### 2/5 — Needs updates *2018-11-03* This is a good idea for an app and the gps tracking works well enough to recognise your speed. This app needs updating though as you cannot set the speed to 0mph over the limit every time I do it jumps back to 10mph over the limit which defeats the point of the app. ### 1/5 — Does not work at all. *2018-03-22, version 1.6.3* Absolute piece of junk. None of its functions work at all. Can’t set alarm speed because it changes back no matter where you set it. Doesn’t know where you are thinks speed limit is 66 no matter where you are. Don’t buy. ### 1/5 — App glich *2018-02-10* It won’t let you set the warning speed to 0 or 5 km over the limit. It keeps resetting to 40. That’s not helpful to avoid speeding tickets! ### 2/5 — Has potential *2015-12-10* This was the only app I could find so purchased. Although on the whole it does work and mostly shows the correct speed limit. It can be confused sometimes changing to a speed limit of a nearby road as you pass a junction. The speed accuracy on the whole isn't to bad but seems slow to react and has real problems when you stop as it takes several seconds to show zero? I hope the writer updates this app as he/she could have a winner here. There are several additions I would like to see 1 Over speed preference in 1 mph stages (35 too high) with ability to save so you don't have to reset each time you load app 2 Have ability to choose own warning sounds from phone alert tones with more volume 3 Bluetooth support ### 1/5 — Doesn't work *2015-05-20* I bought this app. It did not remove the ads and said I was doing 12klms per hour standing still ## Frequently asked questions about Speed Warner ### What is Speed Warner?
