Very Inconsistent, Simple Idea Poorly Executed

This app is painful. It seems that if the movement you are trying to time has any level of beat rate error, Kello bombs out and will not work. It will just hang endlessly on "determine frequency" and "gathering signal data". Then after many minutes of hope, ultimately it will give you an "out of range" or "poor signal quality" error. Get the Timegrapher App instead.
Does it work

Difficult at first, ambient sound has too be very quiet. Tested on Bulova 18,000 bph. Very good App, limited by poor microphone only.
Very inaccurate compared to other apps

I comped results with Hairspring, Watch Tuner (which returns beat error and amplitude) and a hardware time grapher. The results were consistently off (in comparison to other measurements by the aforementioned which were very similar). For equal money look at Watch Tuner. I measured an Omega 286, 30T2 and 2 ETA 2924-2s (with different grade finishes) to determine accuracy of results.
Needs additional equipment or improvement

This app is hit and miss. One of the holy grails for any amateur watch collector is a fast, reliable, easy way to measure accuracy in a mechanical watch. Kello tries, but ultimately fails with too many of my watches to merit an exceptional rating. Depending on the movement and acoustics of the case Kello typically has trouble trying to acquire a reliable signal, which if you're a dive watch collector happens annoyingly often. It's also been my experience that watches with a noisier escapement such as the ETA 2824 have a much easier time being measured than the quieter escapement of Miyota movements. I've followed the best practices in the how to guide and came up with the same result consistently.
Pointless

When I first downloaded this app a while back, it worked ok. Now it just simply cannot hear the watch any longer. Don't bother.
Don’t waste your money.

Unable to get a signal on any watch I tried. Don’t waste your money. There are better apps available.
Cheaper than a Timegrapher

I have successfully used this app to adjust the rate of several Seiko and Orient automatic watches. The tricks are as follows: - place the watch crown down on top of the iPhone microphone on your iPhone earphones/microphone. I usually place a rubber band around the watch once the back is off to insure the microphone is tight against the crown. The microphone must touch the glass crown to conduct sound. - be in a very quiet area - record the rate over a long period of time such as 15 to 20 minutes because the rate will vary over time. - it's hard to adjust to 0 so I settle for anything slightly positive such as 0 to +6 seconds fast per day. At this slightly fast crown down rate the watch when worn on my wrist gains a few seconds per day. When the watch is more than 5 seconds ahead of real time I leave it stem up on my dresser for the night. Leaving it stem up, slows down the movement so it loses about 5 seconds over night. By choosing how many nights I leave the watch stem up versus crown up I can keep the watch within a few seconds of real time. Note a Timegrapher is a much better tool but runs $150.00 and up.
