I downloaded this app and opened it up and used it and not even 5 minutes later my phone battery went super hot very fast I uninstalled it and turned off my phone after it cool off I turned it on and it got HOT very quickly just like after installing this app it also did this on my iPhone 6s and now on my iPhone 7 this app could literally blow my battery I would recommend this app unless you want to buy another phone due to your battery blew and your phone is either on fire or the battery is completely destroyed and the phone no longer turns on this hasn’t happened to me but I heard iPhone batteries can literally blow up just like a bomb I wouldn’t download this app for nothing it’s not worth downloading and end up messing up your iPhone or iPod/iPad I believe this app is full of viruses

Even when trying to view otherwise visible veins, we found this useless regardless of the settings we tried to use. In addition, on an iPhone X running iOS 14, it runs so slowly as to be nearly impossible to use.You would need infrared illumination or a green laser illumination of the correct wavelength to really enable visualization to work. Thankfully nothing was charged for this, but it will be deleted- all it cost me was time.

It’s completely useless. Not effective, at all. Doesn’t show any part of the vascular system. Just a slow blurry black and white image. Maybe you could use it for art or something. Whoever designed this should be embarrassed to release it and claim it is a medical program.

I’ve used other vein finder apps that work so much better. This one didn’t show anything at all and only using it for about a minute or two, my phone started getting super hot.
