## What is Zen Horology?

Zen Horology – For Collectors: Your Personal Watch Collection Manager

The watch collector app for accuracy tracking, daily rate, wear logging, phone timegrapher, magnetism screening, and atomic sync. Catalog your vault, measure mechanical watch performance, and manage every detail in one native iPhone app. Start free with 2 watches.

WHY COLLECTORS CHOOSE ZEN HOROLOGY Whether you own one grail or a full rotation of divers, dress watches, chronographs, and GMTs, Zen Horology keeps specs, timing data, and ownership stories in one private vault — no social feed, no account required.

PRECISION SYNC TIME Synchronize mechanical watches to a live reference clock updating 10 times per second. Sync Assistant adds optional audio ticks and haptic feedback to align the second hand at the top of each minute. Siri Shortcuts included.

WATCH ACCURACY TRACKER Monitor timekeeping over days and weeks. Set a baseline against atomic reference time, log checkpoints, and view daily rate in seconds per day with COSC comparison. Interactive charts reveal drift and when a watch may need service or regulation.

PHONE TIMEGRAPHER — NO EXTRA HARDWARE Turn your iPhone into an acoustic timegrapher. Measure beat rate (vph), view live waveform and trace, test six standard positions, and get coaching plus a service verdict. Premium unlocks beat error and amplitude.

MAGNETISM CHECK Screen watches for magnetization using your iPhone magnetometer. Live and peak readings with clear verdicts and guidance before demagnetization or service.

### 5/5 — Version 1.5.3 fixed issues

*2026-03-28*

I was just beginning to enjoy the premium features of the app … but version 1.5.2 caused several issues. 

I got an email reply and updated… all those issues seem to be resolved and it’s working. 

Thanks for your help resolving this for paying customers.

### 5/5 — Update On My Last Review

*2026-03-26*

The developer responded to my email, my concerns, fixed all of the bugs and the app is back to working very well. 

I revise my last review and would delete it if I could.

**Developer response:** Thanks a lot! Hope you enjoy the app. Please drop me an email anytime if you have any suggestions, feedback or just chat 🙂.

### 1/5 — App Currently Doesn’t Work

*2026-03-08*

The app crashes and freezes frequently. The paid version doesn’t successfully store backups to transfer the data from one device to the next as advertised. The app also currently doesn’t allow new entries to be added without crashing. I emailed the developer for support and haven’t heard back. I canceled my subscription and deleted  the app. Use a more reliable watch tracker and timegraph than this if you’re a collector.

### 1/5 — Version 1.5.2 crashes

*2026-02-15*

I was just beginning to enjoy the premium features of the app … but this version no longer lets me add new watches to my portfolio. Whenever I try to add one, the app crashes. 

I have sent 2 emails for support and have not gotten a reply. 

Thanks for your help resolving this for paying customers.
