Does exactly what I need without any frills. That motivates me a lot. I'm always happy when I enter my weight in the morning ... even when it goes up again?
Marco
Clearly arranged app, very good and easy operation. I like it very much. Advertising remains discreetly in the upper image area. Runs very well on my Samsung A7 (2017). Praise to the developers :-)
Margit
Great App! Does exactly what I need. I am completely satisfied. Have tried many others before. You can also add past weights. And big numbers are an advantage too. We recommend!
