Well, I couldn't get Hupu, the problem might be that my Canadian LG Nexus Smartphone is pre-loaded with hard locked Google software? I can't run some apps, or they don't install, or they are only partly functional with Chinese ISP's and WIFi. Unfortunately, the HUPU install attempt hasn't worked, although a bunch of bulkware did manage to install instead (it was easily de-installed). I have China Mobile CMCC for voice and text, Wechat is fine, and Baidu map works but not with GPS tracking. I am satisfied that my mobile provides a basic level of security and communication despite these issues.
As for Wikiloc, I am satisfied that my mobile can gather all the info I need in China, and store it. I was able to download Wikiloc offline maps by waiting for a not-busy time on a friends Tianjin ISP, I just kept trying the downloads despite fails notices, eventually a sweet-spot came up, and I grabbed three huge offline map files quickly using the Wikiloc mobile app. These Wikiloc offline maps are fairly up to date, of moderate detail, and are correctly geo-referenced.
My unit can save GPS tracks and mobile phone photos referenced to waypoints using the mobile Wikiloc app. The track and location display in real time on the offline base map, making navigation easy. This all goes without connecting to mobile data or Wifi (I turn off mobile data and Wifi to extend battery life). I also take Nikon pics at waypoints for loading to the waypoints later using the Main Wikiloc Website (the main website has limited functionality in China, in my experience, having tried on several laptops and different cell phones. So I cannot fully view or edit my own previous track saves from a China location).
Because of my moblie unit's issues, I will continue with Wikiloc, save all the tracks on my mobile and do the track uploads to the main Wikiloc website later, in Japan or Canada.?
So my biggest disappointments are:
1) my information will not get public currency in near real time, it will all come over a short period, and come much later.
2) Most ordinary Chinese outdoor enthusiasts who would logically be the most interested in the tracks, commentary, and photos made in China are unlikely to be able to access it in large numbers, as they will probably have the same trouble with the main Wikiloc website as I am having in China.
I plan to send these comments to Wikiloc for their interest and consideration. Perhaps they can do some tweaking to remove an obstacle.
