Selected excerpts from our satisfied users:
Thanks to this app, I've lost 16 kg. It shows my healthy BMI so I know I won't overdo it. Just 4 kg left to go. What I love most about it is that it congratulates me every time I lose weight. Try it out and you'll love it.
The success came as I wished! The app has helped me soooo much: since 2019 - about 31!!! kg. A huge thank you for that ❤
The app is really great, I've been using it for years and find it very clear and also motivating. I would give it 10 stars if I could.
