Comments on radio watch sync for Android

★★★★☆ Bosch Dana · Aug 26, 2026
Is there going to be another update for this app 🤷‍♂️🤷‍♂️🤷‍♂️🤷‍♂️🤷‍♂️🤨
★★★★★ Igor K · Sep 26, 2026
It worked with my Casio Pro Trek PRW-35Y. It took approximately 4 minutes to sync, and I had to put the watch in a manual receive mode.
★★★★★ Mátyás Felföldi · Aug 21, 2026
Worked with a Lineage M170T. Volume max on the phone, then moved the watch next to the phone's speaker, synced in two minutes.
★★★★★ Durai Murugan Kannan · Sep 21, 2026
This is the only app that worked on my citizen, and it worked the first time. It took less than 10 minutes in a quiet room to sync.
★★★★★ Bio Hazard · Sep 29, 2026
It worked with my G-Shock, radio band BPC took signal strength to L3 just put watch on phone and leave it for 10 minutes like that in receiving mode
★☆☆☆☆ Smart Media · Oct 19, 2026
I have over 50 Citizen Radio Controlled watches in my collection and can't get this app to work with any of them. A complete waste of my time (literally) and money. Don't bother with this app. And don't believe those who reckon they got it to work. If I can't, neither can they.
★☆☆☆☆ James Skoog · Sep 13, 2026
Doesn't work as advertised. Any reviews that say otherwise are untrue.

Description by jin ning Written by the developer, not by AppBrain. Click to read.
I have a Casio G-Series radio watch, but it is always unable to receive radio waves from time signal station, so I started to write an application to solve this problem.

After some research, I finally wrote this application, which can perfectly simulate the timing signal and happily calibrate the time.

Usage method:
1. Adjust the volume of phone to the maximum.
2. Switch the radio controlled watch / clock to manual wave receiving mode.
3. Click the "start" button.
4. Place the watch / clock near the phone speakers.
5. The synchronization process generally takes 3-10 minutes, please wait patiently.

Matters needing attention:
1. Please try to use the software in a quiet environment to avoid signal interference.
2. The volume of the mobile phone must be adjusted to the maximum. It's too small and the effect is not good.

Characteristic:
1. Supports simulation of all types of Time Wave Signal:
* China BPC
* USA WWVB
* Japan JJY40 / JJY60
* Germany DCF77
* British MSF
2. The unique "Beast Mode" provides higher frequency simulation signals and faster sync.
