I love how simple, reliable and informative this app is. It's truly a worthy companion to my beautiful watch. In particular I love the weekly report on whether the watch has been able to get time sync signals. You absolutely don't need this app, but it adds a lot of value if you use it. This kind of quality engineering is hard to find!

The app works just fine, but I do have to ask why is the app being phased out and replaced with an inferior product (Casio Watches which is nothing but a load of tracking an advertising bloatware)? I will therefore keep using the Oceanus app as long as it works and then my lovely watch goes into the bin! Thanks Casio.

Really easy to use. Some of the graphs are a little confusing though. Cumulative synchronization attempts over the watch's lifetime isn't as useful as e.g. attempts per day. Doesn't really matter though, the core functionality works great with my T3000.
