Using local apps in Vietnam, anyone?

Hello,

I sometimes need to locate quickly a new/nice/interesting place to go and asking via a forum seems not possible.
A friend recommended a local (mobile) app called "InDanang". It's quite useful for me since I have no problem reading and understanding Vietnamese.
For non native speakers I am not so sure, may be the address and directions parts could be useful. Also when you do not have a clear idea of what you want then seeing / searching on a list of options on a map is probably helpful.

But there's actually quite a few local apps for Vietnam, probably too many.
Just want to know if you have used any and maybe share your experience here.

Thanks,
DN

General advise.

Watch app permissions - a lot are asking for access to things they don't need for the app to work, but are really handy for data mining.
