Ratings and reviews

Now useless for timing acceleration. This worked in the past, but now continually waiting for GPS unless you are moving. Occasionally goes over 30% GPS when stationary, and ready for a tenth of a second, and then drops to zero. Other features work if you are moving. I had used this for years on a couple different Samsung phones. It has the best features for acceleration timing, but unfortunately now unusable. Has full location permission and phone set to most accurate GPS. Similar apps GPS work.

Nice and speedy does it!! Only using now for about a week and have done a couple full launch runs with it. I do not have a reference with any official track timing, but the times I got were consistent with the specs for my car, so this seems accurate enough!! I should mention that I am using a separate BT GPS receiver with a rather high update rate. Assuming that the app can use the higher data rates, this will be a factor in the accuracy over those using the phone's GPS. Loving it so far!! 2019-07-07 Update: I contacted the developer and it was so refreshing to get such prompt responses to my questions. I can confirm that the app uses all position updates it gets so my 10 Hz BT receiver enables much more precise speed and distance computations leading to a much more accurate result. Great App!!

Stopped working. GPS signal keeps building, then dropping to zero, even with location permission set to "all the time." My digi-hud speedometer app works perfectly, so it's not the phone or the GPS. they show constant good signal. Turned off battery optimization, uninstall/reinstall, force close everything, reboot, no change. Just does not work. Samsung Galaxy Note 9 on 10.0. Worked fine 3 months ago, no updates showing since 2019. Confusing. 2 stars instead of 1 because it used to function ok.
