They want to many miles for rewards. They want 55000 miles for $10 in Amazon. There us only 25000 miles to go around tye earth once. Most people won't drive 55000 miles in a year. Very unrealistic expectations. Plus how much gas would that use? More the $10 I assure you that. Greedy app developer if not an out right scam. The testimonials they have that are positive have to be paid or faked. There is no way anyone earned the rewards. Waste of time.
