Not for shenzhen – 深圳香港地铁指南 Shenzhen Hong Kong Metro Guide Review

This gives no practical info on shenzhen. I got extremely lost and was stuck with a very expensive hotel because of this app. It has correct info on the hong kong side, but the Shenzhen side, (which is the title,) is useless information that I learned with a simple map offered at the subway. Also crashes a lot.
