User Reviews and Ratings
★★★★☆ It works
App works great to spot check the accuracy of my Submariner. However for $10 I'm expecting more features. Please add a history log, or a graph of some sort so we can see the average.
★★★★☆ It really works
I've got three manual watches that keep varying quality of time, an old Submariner that lost a minute a day, and 40 year old Seiko that lost 30s, and a Panerai that lost 10s/day. Using Kello, I was able to get the Panerai to +\-0.5s/day and the Rolex to +\-4s/day. Unfortunately the Seiko wouldn't work, I suspect the movement's escapement isn't loud enough. It does take some fiddling to find an ideal microphone placement but once you do the app provides consistent and useful results. Highly recom
★★★★★ Fantastic app for those needing to regulate a watch.
I tell you what this app has saved me a ton of time in regulating my watch collection. I have tired a few other ear buds with this app and for sure use the apple ear buds with this app and it will work flawless. I have all my watches running within +\- 2 seconds a day no joke this app is worth every penny and hope to see new functions in the future.
★★★★★ A professional tool not a toy.
Working great exactly the same result of my Vibrograf.
Great job thanks

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