Comments on WWVB Emulator for Android

★★★★★ Bruce Lopez · Jul 19, 2025

Worked perfectly the first time using phone speaker syncing a casio wave captor.

★★★★★ Tobias Hilton · Jun 7, 2024

Great APP for CASIO watches works great for those of us out of signal range

★★★★★ DerekS8625 · Jan 3, 2025

Excellent app! Does exactly what it's intended to do, and makes an excellent backup when the WWVB signal is too weak or compromised. While it may not be 100% to the precise second (it uses your phone clock which may be off by a few milliseconds) according to NIST or USNO atomic time systems, it still does the job VERY well. The key is to have the phone volume all the way up and hold the phone's speaker as close as possible to the antenna system of the time piece you wish to sync. Works well!!!

★★☆☆☆ Paul Richardson · Sep 24, 2021

App works but seems to be about 2 seconds slow when compared to other atomic sources (watch synced via Bluetooth, watch synced via multiband 6, time.is website). I'd rather just manually set it.

★★☆☆☆ Glenn Brockett · Dec 11, 2025

Didn't work with my phone (Samsung A52) and my Citizen watch or "Sky Scan" clock.

★☆☆☆☆ michael · Oct 16, 2021

Ineffective. Watch is now approximately 8 months behind. Instructions for 2 to 3 minutes. Tried for 20 minutes. Not as awful and loud as the last app I've tried. But still just as useless.

★★☆☆☆ Kirk Kohnen · Mar 2, 2022

Doesn't sync to actual time, syncs watch to the phone's time. If the time on the phone is off, the watch will be too.
