    Velociraptor - Map Speed Limit's review

    Check the speed limit of the road you're traveling on, and how fast you're going

    • Brilliant idea, well executed
    • Simple design
    • Step by step instructions
    • Not all roads covered
    • Lagging

    "Need for speed"


    Velociraptor creates a floating speedometer when you use apps like Google Maps (and other navigational tools), pulling data from HERE Maps to provide you with speed limits on the road, and geo-location for tracking your speed.

    Easy to use and quick to set up, this app is a well-designed and undoubtedly useful in-car tool. It still has some glitches to iron out, of course, and not all areas are covered yet.


    Simplicity is the app's biggest plus, and setup is straightforward. Give a few permission to allow the app to fully function, and it will walk you through all the usage steps - it's impossible to get lost within the application because it consists of only one page.

    You can toggle the speedometer on or off, change units and sign style from kph and international to mph and 'Merican', and importantly, set speed limit warnings from 0% to 20% over speed limit (if you really want to know when you're pushing your luck).

    While there might be a couple of competitor apps out there that provide a similar function, Velociraptor is the only one that is completely free with no ads, features Material Design, and is open source, meaning we can all contribute to making it better and more accurate over time.


    Speed limits don't appear to be available on all roads yet - particularly smaller ones. Since data is pulled from HERE maps, when using with Google Maps, info can sometimes take a few extra seconds to load (since they're not fully in sync).

    It has wrong speed limits so it is dangerous to use.

    Like this better than my speedometer. Fast refresh on your speed. Can move the overlay where you want on the screen

    This greatly complements google maps, and I can't live without it. Keeping an eye out for hazards and on the speedo can be a challenge sometimes; the audible warnings are extremely helpful. Yes the OpenStreetMap database isn't 100% accurate, but in the Australian cities that I've used it on, it's probably > 90% and is still mighty helpful.
