Guthook is pretty great, but doesn’t cover outside of the big trails in the US/EU at the moment sadly 
Agree with you though, the thing that makes Guthook stand out is that it acts as a nice centralized space for crowd source info as anyone using it can easily contribute. So it gets beyond, there is a trail here to telling you if there is actually any water in the stream, or that yes this is a camp site but it is ant infested and you are going to have a bad morning.
That’s quite a big jump, and it becomes about ease of use and accessibility that encourages people to casually contribute. The debate in the US is if this is a good thing
Is the adventure gone if you have too much information?
To be honest, the main thing I would love is an “Is there any water?” app. I’m happy with very little info on most things, but with how quickly our climate is changing, even our great resources like the slingsby maps are becoming less reliable for that. And generally when I speak to staff at any of the parks I just get a shrug.
