I wish I could recommend this app, as I love the concept. However. The rewards are minimal. Upwards of 30k+ miles just for $5 in rewards is insane. If you want a free trial or small % off for various services, it's alright, otherwise there isnt much you can get as far as rewards. There is also a hidden "maintenance fee" if you do not remain active. This is determined by your tier level, and you need 750+ miles per month to reach gold tier, which is the first tier for no "maintainance fee".
