Needs lots of work.

First let me assure you the watch is fantastic,rugged ,and works beautifully. The only place I have ever had a gps connection problem in on the Las Vegas strip. I didn’t buy it for that so I don’t care. Out in the Mojave desert it works. I trust my life to it and my motion X app. The problem is two fold. The first is the elevation map on the app quit working with IOS 12. It freezes the app. The second is there’s no way to send the info or photos to any other app for sharing the hike you just completed. The watch itself records the data accurately enough that I can always find my way back. It does take some learning and practice till it becomes 2nd nature. Just fix those two problems listed and I’ll be very happy.

Still no way to share hikes to social media or with friends through email or message.

Please update the app

Overall it’s a clean design and has a good idea. I love the watch, but have only been able to sync the watch and app together maybe 3 times because the app crashes and takes days to let you back in without force closing. Once it works it’s great. However, even with language set, the calendar still shows a different language and I haven no idea what that part of the app says but it looks interesting. Sent in a request multiple times and get the same response to call a number no one answers. Needs cloud backup and health kit accessibility.

Give credit where it’s due

I’ve had some bad experiences with this app but from the gpr-b1000 to a gba-800 and now the awesome Mudmaster gg-b100. The experience has been getting better and better!

With the gg-b100, I’ve never had a Bluetooth connection problem. All the functions that were advertised work and work well. The interface is nice and sending settings back to the watch work. It syncs time, and altitude correction to the watch effortlessly. It doesn’t even show as power drain in iOS even though I’ve got it set to always use location.

Overall, I think Casio has been improving this app and it keeps getting better. Keep in mind, I’ve changed watch models several times and it could be that improving hardware sensors as well.

The gg- b100 for me is the perfect marriage of 3 watches I’ve had before- Rangeman, Mudmaster and the G Squad all mashed up together. It’s also this years release and they have had time to refine their connectivity tech. So I’m giving credit where credit is due.
