Through June 30 the Prosper Daily app will give you 1000 miles if you download their app. It tracks your spending, but you apparently don’t actually have to given them information on your credit cards or bank accounts to earn the miles.
Free and easy miles are almost always a good idea!
Just go to the offer page, enter your last name, zip code and United MileagePlus number, and submit.
On the next page they will ask your phone number. This is so they can text you a download link for the app. (Downloading from Google Play or the Apple Store doesn’t get you the miles.)
Once you download the app and sign up for an account you’ll be on course for 1000 miles in 6-8 weeks.
I value United miles at 1.6 cents apiece so it’s like a free $16, and of course earning these miles will push out the expiration of your United account balance by 18 months.
