Watch Tuner Lite

Works well for me, and given that the selection of apps with this functionality appears to be relatively limited, I’m thankful that someone programmed it so that I avoid buying a 200USD “timegrapher” (which I don’t need for my purposes). The alternative app implementations (of which there appears to be many), where you basically time it yourself based on a visual observation, I find somewhat ridiculous. I placed the watch Caseback or Chrystal on top of the microphone (located a bit down the co

Unlike the many other apps that time watches, this one tells you your watch accuracy within seconds not hours or days. Based on the same principles actual professional watch accuracy instruments work, this app with the help of your earbuds microphone allows you to make adjustments to your mechanical watch movement and immediately check for the change in movement’s accuracy. It is incredible how well this app works without any additional expensive sensors. Thank you so much for developing this!!!

This app may be OK for a watch. I thought it would work also for a grandfather clock, but it isn’t. The app collects a certain number of ticks, and for a watch that’s a minute or two. For a tall clock, with 3600 beats per hour, this takes a l-o-n-g time. Not a good buy for clocks :(

I was a little bit skeptical before I got it, but it turned out to work well. Of course, it is less accurate than a Timegrapher for $100+, but it gives you excellent results nevertheless. The main hint is to put your watch and the mic into a box (preferably with thick walls), so it will catch far less noise than in an open environment (I used my Bose headphones case for that), and keep your phone outside the box to read the measurements.

I don’t normally leave reviews but this warrants one! I tracked my watch visually by atomic time clock but hated the eyeball variance and waiting lol … I didn’t want to shell out hundreds for a pro watch timegrapher, either. I went out on a limb and paid the small fee for this and using Apple EarPods I never use this worked flawlessly!! Detected BPM, and it appears it validates my eyeball atomic method, but can be done in just a minute or two. Top work to the developer; this is one must have co
