## Twelve O'clock Description
Twelve O’clock is an app that helps track your watch accuracy easily in a realistic way.

I can’t stress this enough: it’s “tracking”, not measuring instantaneous accuracy like a timegrapher device.

It’s a manual and oldschool job but it brings so much fun. It reminds me of the old days when I had to synchronize my watch to the clock on the TV at 7pm every day.

With Twelve O'clock you can:

** MANAGE YOUR WATCH COLLECTION

* Add, edit, remove any item in a list of your watch collection
* Include a nice wristshot of each watch


** KNOW YOUR WATCH ACCURACY

* Simply add some checkpoints and let the app calculate the accuracy in *second per day*
* A nice chart of the accuracy over the time

** LEARN MORE ABOUT HOROLOGY

* Curated content for watch lovers (like me)

## Twelve O'clock Reviews in United States

### ***** "Great app made by an enthusiast"
A simple app that does what its job well, with no annoying ads in the free version, and seems to be made by an hobbyist. I love it. My only gripe is the limited number of checkpoints in the free version, but I was happy to pay a dollar to upgrade.
-- Jschu3456, 2025-09-25

### ***** "Loving it!"
I as wondering if you were going to come back to this thing! Been using for awhile and it is great! Any update on possible widgets/cloud sync?
-- jfgarnant, 2025-03-31

### ***** "Works well, and very inexpensive."
Works well, and very inexpensive.
-- Caver b, 2025-03-17

### ***** "Just plain fun and simple"
Accurate way of gauging your watch’s Actual Rate rather than Instant Rate. Timegraphers are fantastic tools for quick and dirty estimations of a watch’s accuracy. This app gets you real world data without having to do the math. Very impressive. Buy the full version, you won’t be disappointed.
-- 48920jeff, 2025-02-20

### *---- "Only five checks"
You can only add five checkpoints and one wrist watch on the free version download something else.
-- Acetow, 2025-01-30

### ***** "Fun!"
Such a neat way to enjoy your watches. It’s so cool to see the differences in movement performance and how positioning and wear affect accuracy. Only gripe is the sort function doesn’t work for me.
-- ecureed, 2025-01-15

### ***** "Fantastic"
This app is fantastic for keeping track of your watches over a longer period and is much better than using a time graph which doesn’t give you a full picture
-- VinylKing, 2024-10-08

### ***** "What a fun amazing app!"
So glad I found this! I think the take a photo option is pretty cool too. I hope the developers keep updating this app and continue to evolve it! Look forward to seeing what else they do! I paid for the full version so worth it.
-- Ben-Tennessee, 2024-09-05

### ***** "Great app for mechanical watches"
I paid $1 for unlimited access and once I figured out how to use it, it became an app I use daily to measure my automatic watches. Simple but gets the job done!
-- BayMiata, 2024-08-14

### **--- "Great app until it deleted all my data"
Seriously LOVED this app until twice in the past several months I opened it, it hung, and then all my accumulated data was gone.
-- Plandersalz, 2024-07-05
