Very annoying that backgrounding app causes loss of tracking - otherwise very good


The loss of track recording when backgrounded is a really annoying feature of an otherwise great app. I contacted their support about it years ago and its still not working. You get home from that mega-trek only to find that nothing has been recorded after a certain time. If you use your iPhone for something then having to remember to get MM back to the foreground isn't too bad (still annoying though), but when an incoming text that you don't know about stops the recording it is infuriating.

On my iPhone MM doesn't appear on the Background App Refresh screen to be enabled - I don't know whether this is the problem?

Apart from that it's a really great app!

Still Doesn't Record Tracks Properly - Useless

York Chris

I got this App when I purchased new maps which I can use on my PC and mobile device. Synchronising routes from PC to mobile is simple and works well. However, recording tracks on the mobile device is useless. The moment the App goes into the background (like when checking email or messages) the tracking stops completely. Once the App is in the foreground again it restarts tracking again. If there is a long gap between the two the App just joins the points with a straight line from where the App went into the background to where it was when it was brought back to the foreground. Absolutely useless! I thought the latest update dated 1 Jun 17 was a fix for this. Well if it was it didn't work!

Still reliable, good support


Used happily for many years and while I empathise with many reviewers who find the interface awkward and the product on the expensive side, it just never goes wrong It’s used on 5 devices now and just does the job every day. If it had more of the features of the desktop app like profiles and a redesigned more intuitive interface I’d give it a 5* instantly. The support I’ve occasionally needed over the years has always been excellent - responsive and helpful.
