Radio Wave Sync App Reviews

It worked the first time I tried it, but now it is asking for a $1.99 payment. My clock has been accurate for several years without the atomic clock signal, so it’s not worth paying anything.

I did not think this was gonna work ngl

I put the watch next to the top speaker of the iPad and it works. Has to turn the volume all the way up too (human can’t hear the wave sound)

It actually worked! Very simple to use.

Idk how but it does work! So far I’ve only tried it on a Citizen watch but today I noticed it had not synced overnight so I gave this app a try and it worked!!

Your iphone speakers are NOT enough. I tried everything/ removed the case from phone, removed caseback from watch, changed RX positions etc. I hooked the phone up to a bluetooth speaker and IT synced the first time! Great App!

Worked great as soon as my alignment was corrected.

今天用了你的软件一次成功!兄弟牛逼！非常感谢!

This app actually works on my Casio PRW6900!

I think this is one of the first reviews I’ve ever left - but after a week of reception failing “No” on my Citizen watch - using this app it received the signal! Note to other citizen owners - you have to make sure the watch hands are on the correct reset position or it won’t update correctly - there’s a video out there showing how to correct that, but thanks to this app, once I did that - it is working! So happy!! Thank you to this developer!!

Not sure if it is just my phone, but it seems like the ad bar in the app silences the audio.

It brings my citizen back to accurate, so great

Amazing! Used to sync my Citizen atomic timekeeping watch without any issues. Although it did take about 30-40 mins. Re title: It obviously uses the radio antenna inside the phone to tx the signal somehow. But what’s unclear is how the app is interfacing with the antenna to do this. Usually you need an SDR to tx and rx radio signals, and this is the only app on the App Store I can seem to find that can use the phones antenna to tx things. Now if only there were an app that allows you to tx anyt

It works great and does change a clock purchased in Japan and used in the US. Could there be a way added for a time zone offset. In the above example it would allow me to not just show Japanese standard time but O could shift to show my local time in the US while using the Japanese radio signal? Possible?

It was hard to get success, I finally managed by positioning the watch underneath the phone, so that the speaker area is resting on the 12 o’clock position of my gshock GW-M5610U, and the 6 o’clock position is resting on the table. The top of the phone was resting on the table and the bottom part with the speakers was resting on the watch 12 o’clock position, with the watch face outward.

I tried first with an iPhone 15 Pro Max and it did not work. I also did not notice any sounds with the volume turned all the way up. I tried the app on an older iPad and it worked on the first try. I could hear the sync sounds being made with the iPad.

I would restore my purchase multiple times a day and it would still play ads even though it would say restore purchase success. Then I would have to wait 5 seconds again for the ad. Please fix.
