It is ok. Nothing spectacular. Works for BMI. Haven't tried much else. Believe it scores a little higher than other calculators. The weight and height indicators are a little hard to use. Tiny arrows or slide too fast and far.

quick and simple, however, if you are slightly over or slightly under a weight there is no in between measures of weight. To be more accurate (198.5 lbs is not measurable so you need to use 199 or 198 for your input and there isn't a tracker on this app.

I'm a disabled Vietnam veteran and I have some medical problems and I have tried some other BMI tables and hated the answers I got but this one was right on. I have a little ways to go but I'll get there now and know MY BMI for sure. GREAT APP. KEEP UP THE GREAT WORK! πŸ‘πŸ‘πŸ‘πŸ‘

Very easy to use..but I prefer typing typing weight with a decimal point. Unfortunately I have to round it up by the nearest weight. But I do like the simplicity
