Welcome to BlueWatcher!    
You are here if you have a CASIO SmartWatch (Bluetooth enabled) and the vendor application does not offer you full functionality for Android devices. Or maybe your Android device is not supported!


BlueWatcher turns your CASIO watch in a really "SmartWatch"!

End Of Life (EOL)

Due to innumerable problems between latest Android versions and Casio's bluetooth modules, BlueWatcher is End-Of-Life. Casio's problems cause the end of life of BlueWatcher. 

NO updates. NO support.

You can get it now for FREE!

Here you can find detailed information about the problems we found:

Casio published last year (06/03/15) an official announcement for Android users ( For us, it was a premature End-Of-Life announcement for its own product.

Smart Casio models are perfect for those who wants a G-Shock (fashion) with some minor smart functions but they lack when you want a really "SMART" watch. Now, Casio has announced it's new Android Wear watch: (WSD-F10) It's a TRUE SMARTWATCH and it is certified with "Military MIL-STD-810G" standard. This is the present for Casio!

* FOR DEVELOPERS: If you want to access BlueWatcher's source code and continue developing/maintaining it, please, contact us. Remember Casio never helped us. All BlueWatcher source code and Bluetooth protocol has been made by our own work.

G-Shock+ application offers incoming call, Mail, Facebook, SMS and Twitter notifications:
  • What's about Whatsapp notifications?
  • What's about my favourite game notifications? 
  • Oh! no! Do I need to enter my email account and password into the vendor app? 
  • Can I see a summary of the Facebook notification message? Answer: NO.

With G-Shock+ application we can control limited music features:

  • Can G-Shock+ App control my phone using my watch buttons? Yes but only the music player! BlueWatcher solves this problem.
