Does the job

Great for tracking mechanical watch accuracy and only a dollar to access all the features. Only suggestion for quality of life is the beeping sound mechanic for the 57, 58, 59, and 60 sec. It only works/ makes sound if the iPhone is not in silent mode (bell icon off).

Great app!

This app is a must-have for anyone with mechanical watches - love the watch accuracy tracking - the beeping on the reference clock is a gamechanger!

Easy to use

Simple. Does exactly what it claims, and makes it easy. One thing I do wish it had is notifications/reminders

Nearly Perfect

Very simple but effective. Only improvement could be a ‘current time’ button when you start tracking a watch to save time (rather than set then click to record current time). It’s free and doesn’t pester you with ads.

Excellent App

Wow, a very well designed app that only requires a very cheap 1 dollar payment for unlimited use. Very cool that it allows for measurement of time at not just the 0s mark but at the other 15s mark intervals too

Must for Automatics

This is a must for automatic movement enthusiasts. Very easy to use, the watch article compilation is a nice touch as well. Full app for only .99 one time purchase.

Чушь

Это приложение не оценивает точность часов, это приложение оценивает скорость реакции владельца и выманивает деньги.

Response from developer

hey! If you don’t trust your shaking finger, use the Photo checkpoint feature instead. Speaking of money: am I swindlering your precious 1 dollar? Or 1 dollar is everything you have? I gave you 5 checkpoints for free. And you can delete them to test over again. Think before you write.

Disappointing

WARNING: Despite paying for premium, this app does not allow you to remove or edit checkpoints without deleting ALL of them, making it completely useless.

Excellent

La perfection pour la dérive quotidienne ! Remplace avec des améliorations toutes les app obsolètes. Tarif dérisoire. À recommander pour vérifier la précision simplement.

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.

Все супер

Но сбивается время ,формат времени !

Must have for watch enthusiasts

A simple & intuitive way to keep track of watch accuracy

Muy bien

La verdad funciona muy bien

Does what it says on the box

Super reasonable price, solves a very relevant problem, and very clean design that’s easy to use. This is what all mobile apps should strive to be.

Perfectly simple

Does exactly what I wanted, simple accuracy tracking. Nice to have choice of every 15s to set it so you don’t have to wait. Flawless.

Delightful App

Elegant and thoughtful way to track your watch collection

Watch collection in an app

Very well designed watch accuracy app. Only takes a few seconds to log your watch's accuracy. I've tried a bunch of watch apps and this is by far the most aesthetically pleasing and intuitive - it's a great way to log your collection too.

Dark mode, clean UI, ability to show time difference by average. It's very well thought out and seems to be developed by a true watch hobbyist.

My only request would be to add the current time back to the checkpoint screen. I often set a watch and create a new basepoint immediately after With version 3, I have to switch between tabs now. Thank you for all the great work.

Awesome app for hobbyists

Tracking the accuracy of my watches is so much fun with this app! Also a great wear to pick which watch from my collection to wear next. Totally worth paying for the “full” version.

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?

Great Alternative to Check Accuracy

This app is a great alternative to a timegrapher for checking a watch’s accuracy. Highly recommend it.
