Well my skyhawk says otherwise ### 5/5 — It works *2026-04-28, version 1.3.16* Sync of Casio watch, no issues. ### 5/5 — G-SHOCK! PERFECT!!! *2026-04-24* G-SHOCK 5610 사용중인데 디른 무료앱과 차원이 다름! 바로 수신완료. 강추합니다. ### 5/5 — Works as advertised *2026-04-21* Seamless, recommended. ### 5/5 — Works but can take some time to find the best setup. *2026-04-13, version 1.3.16* Can confirm works on a Citizen AT6080. If you have trouble - I think the signal transmission is from the coupling of the coils in the speakers to the receiver in the watch, rather than the sound. So just because you can hear the noise, doesn’t mean your watch is properly aligned. I have a Citizen AT6080 and just aligning it with my iPhone speakers doesn’t work. I had to take a pair of over the ear headphones and put the case between the two speakers (facing the speaker coils). It takes 10 mins or so to work but is able to consistently update. ### 5/5 — It works *2026-04-12, version 1.3.16* I got a JDM Citizen that only works with Japanese radio signal. I tried all the other apps, in all the possible configurations and the best I got was a Low signal indicatir and no sync. With this app in worked the firdt try. It really does work. ### 5/5 — Perfect for Casio 5610 *2026-04-10, version 1.3.16* Works perfectly every single time. ### 5/5 — Wonderful multiband 6 watch update app *2026-04-08, version 1.3.16* I reside in South Carolina which is some distance from Fort Collins. So getting a reliable clock update signal to my Casio Pathfinder 3172 PAW-2000T is really hit or miss but mostly miss. This app worked the first time and the signal it produces is strong. I highly recommend this app - 5 stars!!! ### 5/5 — Works for Seiko SBTM257 *2026-03-30, version 1.3.16* Can confirm this works on a Seiko SBTM257 solar radio wave in Australia. Worked first time exactly as described. ### 5/5 — Pls make Apple Watch app *2026-03-29, version 1.3.16* I think it'd be really fun if this was on Apple Watch as well. Then you could help people out by syncing their atomic watches for them using your Apple Watch. Instant street cred. ### 5/5 — Works like a charm *2026-03-28, version 1.3.16* Just synced 2 g shocks, in Toronto where I never get a signal ### 5/5 — GW-M5610U-1B *2026-03-28* Всё работает с часами GW-M5610U-1B.Выставил на часах часовой пояс Япония и в приложении тоже. ### 5/5 — Works *2026-03-22, version 1.3.16* Be patient app says up to 10 mins - it was ! Casio awg-100 in Florida rarely syncs - now I have an easy way to set it accurately- thx ### 5/5 — Just works *2026-03-17, version 1.3.16* It did exactly what it advertised it would do, which is sync my G-Shock. Absolutely worth the $2! ### 5/5 — It works! *2026-03-13, version 1.3.16* Can’t believe it, but it worked flawlessly for my Gshock for when I occasionally have trouble getting reception. ### 5/5 — App really does work *2026-03-11, version 1.3.16* This is my first time leaving a review on any app, but I just want to let everyone know that this app really works. ### 5/5 — Great app *2026-03-01, version 1.3.16* Simple and did what it promised. It set the time on my Casio perfectly. ### 5/5 — Seiko Radio Sync *2026-02-23, version 1.3.16* Wasn’t receiving signal for about 2 days on my Seiko SSG015 after not wearing for a few months. Tried to manual signal over a dozen times with no results until I downloaded the app and watch sync was done in 2 minutes after following the very simple instructions. Worth it for anyone who needs to sync up occasionally or regularly. A+++ ### 5/5 — Black Magic that works! *2026-01-30, version 1.3.16* I thought that there was no way this could work. No way. But I thought for $3 in my local currency (Canada) that what the heck… It works folks. I don’t know how it works but it does. My Marathon atomic time clock can’t get a signal no way no how. I thought it was doomed. The clock does well on its own not shifting the time but it does drift about a minute per year. Now I can use this app to set it straight. I’m amazed this works. Like it’s just crazy that sound waves can create enough RF through the speaker in close proximity to simulate the 60KHz signal. Thank you to the creator! Please come up with a Rasberry Pi package so I can run a series of speakers near my clocks to keep the all in sync in my house. Please Please Please! ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t seem to work *2026-03-12, version 1.3.16* I’ve not gotten this to work once even while wearing the watch and holding my phone up to it. ### 1/5 — Waste of money *2025-12-14, version 1.3.16* Don’t brother, it doesn’t work. ### 1/5 — Does not work *2025-11-16, version 1.3.16* My watches are not syncing whatsoever. Better to use near my window I always get a error on my wave cepter and my gw-6900 looking at reviews I don’t know why it won’t work it I only get 1 out of 3 signals. Needing a refund. ### 1/5 — Sounds good - works bad *2025-08-17, version 1.3.16* App does now work at all!! Does nothing when I launch it- I think apple’s latest update broke this app ### 1/5 — Don’t work for my citizen watch *2025-04-30, version 1.3.16* Simply didn’t work. I tried different country transmitters. Then closed the app and the watch synced itself with the German transmitter. ### 1/5 — For me, it didn’t work at all *2024-11-03, version 1.3.16* For me, this app was a waste of money. I did everything that the tutorial told me to do a few times. The watch kept defaulting from get back to the main screen. I let it go for about six or seven minutes at one point. Maybe I’m doing something wrong. ### 1/5 — Did not work for Marathon Atomic Clocks *2024-08-04, version 1.3.16* Ran for 10-20 minutes in different positions near two different model Marathon Atomic Clocks without success. ### 1/5 — Don't waste your times and money *2024-07-28, version 1.3.16* I tried with Citizen, Casio, and Seiko radio wave controlled watches. None of them works. Do more reach on the Internet. Don't trust those YouTube videos review. They got paid to lie. Sound wave is totally different than radio wave. You can't make your iphone to produce radio wave. Apple will be in deep trouble with FCC. If their phone can do that, it will create a lot of radio frequency interference. ### 1/5 — Crappy waste of $$$ *2024-03-12, version 1.3.16* Crappy, I think a scam. Did not do anything!!! ### 1/5 — Not worth it *2023-05-03* I thought that because it is a paid app, it will at least work, if not seamlessly. But I tried to sync my atomic watch 15 times and it couldn’t receive time. And so I tried a free app and it worked way way better. Really, Very bad execution. ## Most praised reviews (10 highest-rated) ### 5/5 — Works as advertised *2026-08-30, version 1.3.16* I was thinking twice about whether it would work for my g shock 3495 module square with a phone, it just works as stated. The clean simple UI / app is a great addition to my watch, definitely worth $2. Keeping watch on the phone or iPad over the loudest speaker (you can do hearing test to see where it is loudest), and then letting watch sit on it does the job in 3-4mins. ### 5/5 — Best 2 Bucks I Ever Spent *2026-08-06, version 1.3.16* I have three atomic timekeeper watches and one of them is just so finicky and was driving me nuts because I couldn’t get it to synchronize. I found out about this app from another user and the very first time I used it my watch synchronized. This app is absolutely worth $2. I just wish I would have known about it sooner. ### 5/5 — Awesome *2026-07-30, version 1.3.16* Awesome!! ### 5/5 — Excellent *2026-07-22, version 1.3.16* Works like a charm. Thank you. ### 5/5 — Absolutely brilliant *2026-07-01, version 1.3.16* I moved house and my watch no longer could receive a signal to update my watch I tried a few different apps but none off them worked but this one did 100% recommended it’s worth the £1.99 I paid ### 5/5 — It really WORKS!!!! This one, not the free one *2026-06-13, version 1.3.16* CLOCK WAVE is the one to get. Worth the 2 bucks. First attempt it worked perfectly with Casio 5161 moduled watch 12 o’clock positioned next to iPhone speaker. I tried the other app that was free but had a paid upgrade and I tried it a 100 different ways with iPhone speaker, Bluetooth speaker, headphones over an hour I wasted and it never worked. Get this one. It worked first try in a medium noisy public environment. I want to send them an extra $2 as a tip because this actually works without wasting any time. My thanks to the developer. ### 5/5 — The best app of this sort out there *2026-06-06, version 1.3.16* Works flawless for my Citizen Eco-Drive H800 movement. Takes exactly 3 minutes every time. I’ve tried nearly every other app available in the Apple Store to sync a radio controlled watch and all of them were waste of time for me. So glad this app exists. ### 5/5 — It works *2026-06-03, version 1.3.16* Used it on my citizen radio control model and it worked! Very simple, took about 8-10 mins. ### 5/5 — Works as Advertised *2026-05-31, version 1.3.16* I downloaded this app to sync an atomic clock that is out of range of the standard time signal due to its location in the house. I followed the simple instructions and within minutes by atomic clock was synced and displaying the correct time, down to the second. Great app! ### 5/5 — Funcional *2026-05-22* Parabéns! O app funciona mesmo. Acertei a hora de dois relógios citizen rádio controlado. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
