I have found Alipay transport features to work best for both subay and bus embarkation scanning.
Similar to Didi, Alipay's built-in bus map route is also easy to use and accurate. Hello Bike, new Hello ebike, and taxi hailing also available within app.
Located inside Alipay app, under "Traffic" mini program (交通出行): First tab is for bus, next for subway, then bike renting, last tab to the right is cab hailing.
Right now Alipay is offering promotional 40% discount if you purchase week long bus package. 30% off for metro/subway card. Discount valid for two trips a day for seven days.
Convenient and widely used by local commuters (younger professionals and students) for a good reason.
