    Not sure about the "barrage of ads" reviews this app has gotten in the past but I've been using the free version for 3 years and never had more than 1 ad pop up every 3rd or 4th time I used it--and the ad was dismissible immediately. I'm not in the medical field so critical life-threatening measurements that are off by a few hundredths aren't a problem for me. I'm in Europe so the shoe size converter is a godsend to my wife, and I'm a big fan of the currency and metric conversions. I figured I've used it so much I might as well pay for the ad-free version (expensive) but what the hell..$2 for a lifetime of convenience isn't bad. One problem though: when I try to add a custom measurement the app crashes every time. Fix that, and I'd give it 5 stars.

    I used this app Every Single Day for my classes for Years. I've had this app for 5+ years using it every day. I had this app on my iPod before I even advanced to an iPhone. But now, whenever I Need to use my app, I'm barraged with pop-up ads. Furthermore, you can't immediately exit the ads. You have to just watch their little annoying show for however long they deem you should. After 5 years of daily use, I'm done and deleting this app. I'm switching to a different, more reliable, more functional app. Its a shame that the developers took such a good app that I relied on daily and ruined it for the sake of some extra $$.

    At least some of the metric unit conversions are flat out wrong by an order of magnitude. I was double checking my math on a dose calculation for a medication, and was trying to covert between mg and mcg. The answer seemed wrong, and I realized that the app thinks there are 10,000 mcg in a mg. I checked its mg to gram calculation, and that was wrong too. Deleting this app immediately, as it is useless and a potential liability. I'd give it zero stars if I could.
