What mobile APP has the most comprehensive hotel price comparison?

I don't agree with what is said upstairs. Although the price of where to go is more comprehensive, wouldn't it be more comprehensive if there was an APP that included the price of where to go? You can check the hotel price on the public comment, because it has hotel quotations from some foreign mainstream hotel suppliers, such as Qunar, E Long, Ctrip, booking and agoda. One APP can be done, and it's too much trouble to spend energy watching multiple apps.
