In the coming weeks, customers who order a meal via DoorDash, the nation’s biggest food-delivery app, will get something extra: a promise that when they tip, the money will go straight to the worker, rather than into DoorDash’s pocket.

The company’s one million delivery workers will also get something else extra: an increase in minimum base pay.

The result, the company promised on Thursday, will be that on average, the workers, known as Dashers, will make more money — though how much more remains unclear — and “on average” means that some Dashers will make more and others will make less on a particular order.

DoorDash had been widely criticized for its old pay model, in which customer tips effectively went to DoorDash rather than to the worker in many cases. Last month, after a New York Times article described the tip policy, the company said it would drop it.
