Of course, it is less accurate than a Timegrapher for $100+, but it gives you excellent results nevertheless. The main hint is to put your watch and the mic into a box (preferably with thick walls), so it will catch far less noise than in an open environment (I used my Bose headphones case for that), and keep your phone outside the box to read the measurements. ### 5/5 — Great alternative to dedicated timegrapher *2021-07-19, version 1.11* While learning about how to regulate my mechanical watches, I game across this app. Buying a dedicated timegrapher seemed impractical. I used it to regulate the 7s26 movement in my Seiko SKX013. At first it gave me some strange results, but after playing with the microphone sensitivity it was reporting roughly what I’d been observing. It worked well using the built in microphone on my iPhone XS about 1 cm from the case (with case back on). I had the phone and watch on a desk on a mousepad in a very quiet room. I think a help screen would be nice, but after fiddling with it, it’s pretty straightforward. This combined with Marc’s video on how to regulate a movement on the Long Island Watch YouTube channel were extremely helpful. ### 2/5 — Not for case clocks *2021-06-09* This app may be OK for a watch. I thought it would work also for a grandfather clock, but it isn’t. The app collects a certain number of ticks, and for a watch that’s a minute or two. For a tall clock, with 3600 beats per hour, this takes a l-o-n-g time. Not a good buy for clocks :( ### 5/5 — It really does work *2021-04-26* It does take some fiddling... I was actually about to give this app a negative review but just before I did, I decided to read the instructions one more time. Rather than placing the mic on the crystal as some have said, the app instructions state that you should place the mic against the crown of the watch. As soon as I did that it worked! Awesome little app 🙌🏾 ### 5/5 — The only review I’ve ever written *2021-04-20* This worked exactly as expected. Like reallly really well. It’s obviously not a timegrapher, but if you use as directed you can set a Seiko 7s28 to within +\- 5 seconds/day or better. I hid in a quiet closet away from my loud kids and opened the caseback, set my iPhone wired earbuds mic on the case, and got a signal no problem. The measurement is way more accurate than your ability to push the 7s28 regulating lever, so it takes a few tries. I bought this thinking it might be a bust. It was so super good this is the only online review for anything I’ve ever written. If it’s not working for you, you’re not following the directions. The accuracy I have on an SKX007 is (for now) within 2 seconds/day and it feels like a million bucks because of it. Great job! ### 2/5 — 磁気帯びします。あたりまえですが。 *2021-04-16* 計測にあたっては、時計からでてくる音をマイクから拾っています。iPhoneのマイク部分にはスピーカーがあるので本体のマイクで拾うと磁気帯びします。私の持っているアンティーク機械式時計は短時間でも全て磁気帯びしました。イヤホンのマイクにも磁気があります。当然ですがこのアプリを使うには磁気帯びのリスクが大です。そして計測できたと思っていても磁気の影響を受けているので正確な測定はできません。 ### 5/5 — Works just fine *2021-04-06* Nice app. Took a bit is experimenting- Use the headphone microphone as instructed and wrap the watch and mic in a cloth to improve results. Need to adjust sensitivity to suit your watch. Very useful for examining your mechanical watch and even allows you to easily check positional orientation accuracy ### 4/5 — Fonctionnel *2021-03-26* Fonctionne bien et m’a permis de régler un mouvement NH35A assez silencieux juste avec le micro de l’IPhone 😄. Donc assez satisfait ! ### 5/5 — Работает на ура *2021-02-13* Измерять лучше всего в железной кастрюле, без шуток! ### 5/5 — Good ! *2021-02-02* Perfect for me. But please add a dark graphic theme ! Thanks ## Most critical reviews (10 lowest-rated) ### 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 ### 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. ### 1/5 — +329 s/d…no matter what. *2022-08-04, version 1.12* Make all the adjustments you want, it’s +329 s/d. ### 1/5 — Doesn’t work *2022-04-28* I tried this on a variety of watches. I tried watch crown to iPhone microphone. I tried wired iPod microphone. I turned sensitivity up and down. Noise cancelling on and off. I could not even get a remotely accurate measurement of beats per hour. I get too much noise or no signal. Two days of fiddling. Also does not work even with the case back taken off of a noisy watch. ### 1/5 — Can I have a refund? This is crap *2022-04-13* Can I have a refund? This is crap ### 1/5 — Vraiment peu précis *2021-12-24* Que ça soit avec le microphone interne ou un casque Apple, les mesures font des bons de 20 à 40 secondes quels que soient les réglages choisis : inutilisable ! ### 1/5 — Не работает *2021-05-30* Не работает, частоту определяет неправильно. ### 1/5 — 計測出来ない *2021-03-17* ほぼ計測出来ないと考えた方が良いソフトです。 時計の音が少し離れた距離でも聞こえるアンティークウォッチで唯一計測出来ましたが、最近の時計は計測出来ませんでした。 ### 1/5 — Complete waste of money. Do Not Buy *2020-10-20* I would like a refund. This app is worthless. It took about 5 tries, 20-30 min each (before giving up) to finally have it give me a reading of -329 sec/day. That’s ridiculous. The test watch is -2 sec/day. Anyone know how I can get my money back, because I can’t get that last hour of my life back. ## Most praised reviews (10 highest-rated) ### 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. ### 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. ### 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! ### 5/5 — Fonctionne très bien *2022-11-03* Mesures rapides et fiables dès la première utilisation. Bien suivre les conseils du développeur. Je n’ai pas eu besoin des écouteurs. Le micro de l’iPhone (12 mini) a fait le job. ### 5/5 — Exceeded expectations!! *2022-07-02* I don’t normally leave reviews but this warrants one! I tracked my watch visually by atomic time clock but hated the eyeball variance and waiting lol … I didn’t want to shell out hundreds for a pro watch timegrapher, either. I went out on a limb and paid the small fee for this and using Apple EarPods I never use this worked flawlessly!! Detected BPM, and it appears it validates my eyeball atomic method, but can be done in just a minute or two. Top work to the developer; this is one must have cool little app :-) ### 5/5 — Excellent app *2022-04-19* I was sceptical at first but, if you follow the direction to keep external noise minimal and take the case back off the watch using the mic from the iPhone earbuds I managed to get two stubborn mechanical watches to within 15secs p/day in just a few minutes. After a few weeks of trial and mainly error getting them regulated that is a result! Thank you. ### 5/5 — Parfait pour petit réglage basic *2022-02-04* Acheter suite commentaire du haut egalement pour regler un nh35 , parfait , fait bien le job meme avec un iphone 6, du coup toutes les meca y sont passées également ... content 😊 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
