Smart Watch 3 SWR50 - Any Solid Apps?

I've ordered a SM 3 and I'm interested if anyone knows any good apps for it. Especially related to running, an app that keeps track of location/speed/etc. without dropping GPS connection or other silly bugs. Any other interesting apps unrelated to fitness you might know are greatly appreciated also.
Please just mention apps you've used personaly and been pleased with them.

Is the LG G2 still a solid buy?

As many other people I was thoroughly dissapointed by todays Nexus release.
At the moment I am using a N5 but I smashed my screen so I am looking for a "new" device.
5" is the perfect size for me. No need to go bigger, also QHD is just a stupid waste of battery on a phone (imho)
There aren't too many devices around with good battery, 5" and 1080p so I am currently thinking about getting a G2.
Now I am used to Nexus roms with everything working and fast updates. How does the G2 fare?
I see quite a few roms out there but I also read quite a bit about random reboots, gps issues and so on.
Is the G2 a good phone to get if I am looking to flash roms. Has LG confirmed it will be getting Android M?
Im really at a loss for a phone that fits my bill. The only other phone I fancy atm is the Xperia Z5 Compact but its so friggin expensive.
So yeah.

G2 or not G2?
Thanks guys

Phone Died won't charge and SOLID orange light when plugged in

I have been doing a lot of research and can not find an issue exactly like mine at all!!! I need help.
So I was in the middle of texting and the HTC one M8 shut down ( I think the battery was low at the time). I put it on the factory charger that came with the unit and I get a SOLID ORANGE LIGHT, No icons, no battery images on the screen of any type. Just a solid orange light. I have tried many different charges and no luck there (as per other threads). I have tried the battery re-calibration many times - does nothing. I can not seem to get into recovery mode either, I think fast boot is on..... (has I only know to turn it off....). I have even tried leaving it on the factory charger for 3 days (I had given up and forgot about it lol) and nothing still a SOLID ORANGE LIGHT. Tried a battery re-calibrtation at this point and nothing again. Tried recovery modes at this time and still nothing...
Is the battery the culprit?
Can anyone cast a ray of hope that I can fix this thing, I NEED to get back on I have too much to loose on it :(
