User Reviews

Users frequently praise its ability to sync a range of watches quickly and affordably, with many reporting first-time success. However, performance can be inconsistent, and success often depends on careful device alignment and signal strength, making it unreliable in some locations. Overall, it’s a valuable tool when it works.
Pros
  • Works across many watch models (Casio, G‑Shock, Citizen, etc.)
  • Quick to sync (often takes only a few minutes, sometimes first-time success)
  • Good value for money (worth the $2)
  • Easy to use with simple instructions
  • Helps in areas with weak radio reception or poor signal where manual syncing is difficult
Cons
  • Inconsistent performance; sometimes doesn’t work or fails to sync
  • Requires careful alignment/positioning; success depends on placement of the watch and phone
  • Signal reception varies by location; in weak-signal areas it can be hit-or-miss
  • Some users report it doesn’t work or stops functioning (possible updates/compatibility issues)

Used it on my citizen radio control model and it worked! Very simple, took about 8-10 mins.

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!

I can’t believe it, other apps failed, Claude said this wouldn’t work. Well my skyhawk says otherwise
