Frequently Asked Questions

How do I start tracking a watch?

Open any watch from your collection and swipe the "Swipe to Wear" slider to start tracking. You can also backdate to the moment you put it on, add a note, or set full details. From the Home tab, tap any watch in the "Recently Worn" or "Needs Love" sections for quick access.

How does the free trial work?

When you first install WearTime, you automatically get a 30-day free trial with full access to all Pro features. No credit card is required. After the trial ends, you can continue using the free tier (3 watches, basic features) or subscribe to Pro for unlimited access.

What happens to my data if I don't subscribe?

Your data is always preserved! If your trial ends and you don't subscribe, you'll still have access to your first 3 watches and all your wear history. You just won't be able to add more watches or access Pro features until you subscribe.

How do I cancel my subscription?

Subscriptions are managed through your Apple ID. Go to Settings → [Your Name] → Subscriptions → WearTime → Cancel Subscription. You'll retain Pro access until the end of your current billing period.

Is my data backed up?

By default, your data is stored locally on your device and included in your iPhone backups. You can also enable iCloud Sync in Settings → Data & Sync to keep your collection in sync across devices using your personal iCloud account.

Does WearTime have widgets?

Yes. WearTime includes Home Screen and Lock Screen widgets in multiple sizes. Widgets show your currently worn watch with watch photos, wear time, and collection stats. The Large widget also displays random diary memories (Pro feature). Add them from the iOS widget gallery.

How do I add photos to a watch?

Open any watch from your Collection, then tap the Camera or Library button below the main image. You can add up to 15 photos per watch with a Pro subscription (1 photo in the free tier). The app uses smart cropping to focus on the watch dial.

How does smart detection work?

When adding a new watch, you can take or select a photo and the app will automatically try to detect the brand, model, and reference number using image recognition. This saves time and helps ensure accuracy.

Can I track multiple watches at once?

Yes! With a Pro subscription, you can track up to 6 watches being worn simultaneously. This is great for collectors who wear multiple watches or want to track watches on different wrists. Free users can track 1 watch at a time.

How do service reminders work?

Set a service interval for each watch (e.g., 5 years) and the app will track when service is due. The Collection view shows status indicators: green (OK), yellow (due soon), red (overdue). You can also set daily reminders to check your active watch.

How does the Timegrapher work?

The Timegrapher uses your iPhone's microphone to listen to the tick of your mechanical watch. It detects each beat and calculates rate (seconds gained or lost per day), beat error (timing symmetry), and BPH (beats per hour). Place your watch near the microphone — the app shows you exactly where — and hold still for about 15-20 seconds. Readings stabilize automatically, and the measurement stops when enough data is collected.

How do I get the best Timegrapher results?

A few things make a big difference:

  • Remove your phone case — it can dampen the microphone
  • Try both the dial and caseback to find the louder side
  • Place the watch on a soft surface to reduce vibrations
  • Move away from fans, AC, or other noise sources
  • Hold your phone as still as possible during measurement
  • Wait for the full stabilization period (about 15 seconds) before trusting readings

If you know your watch's BPH, set it in the watch details before measuring — this gives faster, more accurate results. The app also supports directional microphone mode on newer iPhones for better noise rejection.

What do the Timegrapher readings mean?

Rate (s/d): How many seconds your watch gains (+) or loses (-) per day. Under ±4 s/d is excellent (COSC chronometer spec), ±4-7 is good, ±7-20 is fair, and over ±20 may need regulation.

Beat error (ms): How symmetrical each tick-tock cycle is. Under 0.5 ms is excellent, 0.5-1.0 is acceptable, over 2.0 ms may need adjustment by a watchmaker.

BPH: Beats per hour — the frequency of your movement. Common values are 21,600 (3 Hz), 28,800 (4 Hz), and 36,000 (5 Hz). The app auto-detects this, or you can lock it if you know your movement's frequency.

The Timegrapher isn't detecting my watch. What should I try?

First, make sure your watch is wound and running. Then try these steps:

  • Move the watch closer to the microphone position shown in the guide
  • Try the other side of the watch (dial vs caseback)
  • Remove your phone case
  • Make sure the environment is quiet — background noise can interfere
  • If your watch has a soft tick, try placing a cloth between the phone and watch for better acoustic coupling

Some movements are quieter than others. Vintage movements and certain high-end finishing can produce softer ticks that are harder to detect in noisy environments.

How do I export my data?

With a Pro subscription, go to Settings → Export Data. You can export your complete collection and wear history as JSON or CSV files for backup or analysis.

What's the difference between Monthly and Yearly subscriptions?

Both subscriptions unlock the exact same Pro features. The annual subscription costs $12.99/year, saving you 45% compared to the monthly subscription at $1.99/month. The annual plan is the best value for committed collectors.

I have a promo code. How do I redeem it?

Go to Settings → Subscription → Redeem Code. This will open Apple's offer code redemption sheet where you can enter your code. Once redeemed, your subscription will be activated immediately.
