Colour me impressed. I was out trail building in the bush, mowing weeds and cutting back undergrowth. Twice before I’ve lost my Fitbit 1 along the 8km of trail that I maintain, and both times I got lucky and happened to spot it on the ground. This time, no luck. The grass was waist high and who knows where it fell. Couldn’t find it after 3km of checking. A quick search turned up this app. $4.99 seemed worth the chance of not replacing my Fitbit. And wow, does it work! I walked back along the trail where I thought I lost the Fitbit, pinging the app repeatedly. Within minutes I got a signal, and a quick back-and-forth with the signal strength meter narrowed the location to within a metre. And there it was, under some long grass. Very impressive bit of software that does exactly what’s promised, very easily, and very fast. The signal strength meter is nicely done! Good job, Front Seat!
