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.

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!

Great community!

Just completed my first two DietBets! Loved Jenn, the creator of my bets, her ideas, her challenges! Happy with my progress and love the community feel and support!
The app was easy to navigate with a little use. App does not allow the use of emoji's which looked strange.
I wish there was a link on my profile to see just my activities, posts, likes, and comments. Also, I could find the pictures that I posted but couldn't get them to load right side up, or zoom in on them.
I had to scroll for a long time to see my actual posts. Same for the people who liked and commented on my posts and who I liked and commented on. I could not find a particular person's posts by any sort of search that I could find. The only way I could find a person was to go back to my notifications and search for them by name. Wish the app allowed a simpler way to connect with people.
I will probably do another DietBet. DietBet helped a lot and I really got into the challenge! It was also great to be able to scroll through this app instead of one of my others when I have downtime.
