Powered by group dynamics. Built in the UK. Most diets fail by month two. Not because they're bad plans — because you do them alone. thinr puts you in a weight loss group of around 12 people. You all weigh in on the same day, every week. You see how everyone's getting on. They see you. It's totally anonymous, but it works. Massively. This is what Weight Watchers and Slimming World figured out 60 years ago. We're just the version that fits in your pocket. WHAT YOU GET — A group of around 12 people on your weigh-in day — A weekly board showing how everyone did — Daily commitments you set yourself — Your weight, photos, and progress over time — Optional GLP-1 tracking if you're on medication WHY IT WORKS Sustainable weight loss isn't about a magic plan. It's small daily things you can actually stick to — and people watching to see if you do them. You set commitments. You tick them off as you go. Once a week you weigh in. Your group does the same. Over time, you see what's working. NO DIETS, NO TRICKS — No calorie counting — No meal plans — No points systems — No before/after pressure — No paywalls Free to use. No sign up. WHO IT'S FOR People who've tried diets and want something different. People on GLP-1 medications who want to track properly. People who just need eleven other people watching to actually stick to it this time. Built in the UK. Made for the long game.
