I started using the DietBet app in February 2019. I’m down 30 lbs. since 1 January, 25 of that list in the program. I appreciate the accountability, community, and competition. Trying to take a full length photo of myself with the scale numbers visible is challenging when you live alone, but every other aspect of DietBet has been easy. I’m very happy with the friendly, helpful customer support personnel. They answer email or messages in the app very quickly. And, they appear to be actual humans— encouraging, upbeat people who actually care about the customer— not programmed machine answers you get from most tech support now. I’m within 3 lbs. of my goal for the end of this game on 28 July. If I keep steady, I’ll easily make it and start on a new game. I’ve struggled with weight for decades. DietBet is the first success I’ve had in a while. To be honest, I don’t know why DietBet is working for me when other programs didn’t. Whatever the program variables are that are helping me to success, I’m going to keep on using this app. First success in years, and I don’t argue with success. I hope it works for you, too.

Still doing it to lose weight but

I had the same issue as everyone. Losing money…even though I won. Specifically mine was StepBet, and I was doing really well, I was up to 20,000 steps even tho my goal was under 9,000. I was feeling amazing, and then another issue happened. Since it was my first game and one w a prize I didn’t realize that they awarded the prize before the game was even over. I mean the prize was a pair of shoes, I mean I need a new pair of shoes like I need a moose for a pet, but I still feel like the prize should go to someone who has won the game, guess that’s just crazy talk? I slumped into a depression like no other. I went from 20,000 steps to just doing my goal of under 9000. By the time I “won” I was fat and weighed more than my original starting weight, I never would have thought it would be that much of a mindkiller, but it was, sucked the joy right out of me.

When I first signed up for this particular app the screen page was misleading it made it look like you had to either buy into the monthly membership or the yearly membership, however if you looked at the far right corner there is an “X” if you click that you don’t have to pay a membership and can be a nonmember. I see that they keep claiming “operating costs” for why they take 25% of the pot…but I mean it would be nice if they detailed what those operation costs were, then maybe people wouldn’t be so miffed.

HI Callie - Thank you for taking the time to leave your review. We are sorry you had such a negative reaction to the prize offered in the game. We feel that all participants in a game deserve a shot at the additional prize. Winners get their cut of the pot, but everyone who tries should also have a chance at winning something exciting, at least from our point of view.

Also, we are sorry for the confusion regarding membership. Operating costs are just the same as other businesses; equipment, paying employees, access to outside programming, developing new programs, etc. We also offer prizes pretty regularly across all our products, some being big ticket items like smart fridges and pelotons - so whenever possible, our costs go back to our amazing players.

EXCELLENT customer service!

I’ve been using DietBet and its sister app, StepBet, for a few months now. They have both been great motivation during lockdown when it would be too easy to sit around doing nothing. l’ve lost 15 pounds! If you’re wondering how much you “win”, for a $100 bet (non-member games, which is usually a lower payout because they take out a percentage for overhead) I’ve gotten back amounts ranging from $4-15. I hear that lower stakes games actually give a better return, but I’m not trying to invest here, my motivator is not losing my $100. :)

The main reason I’m writing this review is that I am continually impressed by this app’s customer service. They reply very quickly, replies are personal and kind, they clearly read your message and take the time to understand your problem, and 100% of the time I have been happy with the resolution. I don’t have any more weight to lose but I will keep using both apps (DietBet has weight maintenance games) in large part because of their great support staff. Give those ladies a raise!
