THIS APP IS OK,BUT IT SCREWS UP EVERY TWO OR THREE DAYS.THE PROMOES are very hindering because when you have promotes its during the slow times and when you get a trip its way out in neverland.so by the time you get back to civilization you are waiting thirty minutes for a trip.so you are not coming out ahead compared to no promo day. I make the same either/or. There on the dasher help line need to speek English and have some common sense and quit acting stupid.they are very incompete
