## What is Watch Tuner Lite?

Watch Tuner Lite measures the accuracy of mechanical and automatic watches. It uses the built-in microphone or headset microphone to record the audible tick of the watch and calculates the seconds-per-day deviation. Works with almost any 'ticking' watch/clock.

Use in a quiet environment. Any ambient noise can affect the accuracy of the results. Complete silence is best.

Recommended way to record the ticks is to touch the crown of the watch with the headset microphone. You will get the best results using original Apple EarPods.

This is a simple version of Watch Tuner application. Not everyone needs detailed information about a watch movement, sometimes only accuracy is important. Watch Tuner Lite uses very similar algorithm like Watch Tuner does but displays only seconds-per-day deviation.

If you want to know how much your watch is fast or slow, this application is for you.
If you prefer to measure also beat error and amplitude, try Watch Tuner - a bigger brother of this app.
If you need frequency diagram look at Watch Tuner Timegrapher - the most sophisticated app of Watch Tuner series.

### 5/5 — Great app

*2026-02-20*

Works well and is very easy to use.

### 5/5 — Phenomenal

*2025-11-24*

This app works like a charm to adjust watch accuracy with the help of apple earbuds it accurately measures time error of your time piece instantly allowing you to adjust your watch to the correct speed in one setting. What an amazing tool!!!!

### 5/5 — Отлично!⏱️

*2025-06-20*

Отличное приложение! Если в тишине измерять- работает на ура! Спасибо разработчикам.

### 5/5 — Worked as intended

*2025-04-29*

Keep it in a quiet area and adjust the sensitivity and it’ll help you get the right time set. Intuitive and simple, set +- 2 seconds for my 1913 Elgin that I’m sure fluctuates more from temperature than this can fix.

### 1/5 — Waste of money

*2025-04-05*

Please save your money,this doesn’t work.Tried on a new iPhone and it’s just a few hours of frustration you will never get back

### 2/5 — Works sometimes

*2024-11-04*

Not very accurate, works occasionally

### 5/5 — Works great

*2024-01-05*

Didn’t think this would work but matches up exactly to what I was told when buying watch.

### 1/5 — 👎

*2023-07-31*

Не работает :(

### 1/5 — Arnaque

*2023-04-14*

Aucune utilité ou fiabilité ni avec le microphone de l’iphone ni avec celui des Airpods.

### 5/5 — Works with the right microphone and settings

*2022-11-14*

I was able to get a reading when laying my watch face down on my iPhone near the built-in microphone (in the lower left corner). It didn’t work when laying the watch on its side—not loud enough. This did not allow me to measure my watch in different positions. 
I tried using my original AirPods, but that didn’t work at all. 
I finally pulled out the wired headphones that came with one of my iPhones. I held the microphone part against the back of the watch with a wire tie wrap. Masking tape should work even better. I set sensitivity = 2/3, noise cancellation = on, and measuring time = long. This produced stable results in most positions. These generally agreed with my seconds/day measurements for 24 hours, but of course is much faster!
