Baidu Maps and Tencent maps have similar functionality to Amap in terms of plotting out public transit routes. Each app has its own strengths and weaknesses, so I tend to rotate through all three.

This is late, but there is a free app in both English with Chinese names, for subway/metro timetables, called MetroMan. It has many cities in China in the same app, download the relevant timetable within the app, and select the departure and destination stop, and it tells you how and where to transfer if needed and ticket cost too!
