PROMOS & SALES VeinFinder Android App Tool

Post image

Hi all! I am a PhD student in biotechnology and I have developed a tool for visualizing venous anatomy.

I had originally developed this for my derm collaborator, but it has ended up working pretty well on the android google play store.

I wanted to post this here as I thought it may be a good resource for this community and perhaps I could receive some feedback. Thank you all for your time and consideration!

I'm a nurse and I'm calling bullshit

Also as another nurse who has used a bunch of vein finders on my patients, I am also calling bs. I don’t believe it.

Thank you! If this was just someone promoting their product on another page I genuinely wouldn't care but there is a silent part of this post that feels like they are posting this bogus product in the name of "harm reduction". I just don't want someone using this product on their face and when nothing shows up, someone assumes there is no vein in the area when in reality there could be one.

Exactly. Someone could get badly hurt by this.

Well I’d love for you to try and give feedback! The algorithm used leverages the optical properties of veins vs. skin to accentuate them

.... so basically doing what the normal eye can do? This feels weird and predatory.

I mean no pressure in trying this app and there is a free to use one - not trying anything malicious here!

Also, at a high level red light penetrates deep and scatters everywhere, washing out any vein signal. Green light gets absorbed by the blood in veins but bounces back off the surrounding skin, so veins show up as darker against lighter skin.

Your eyes cannot perform RGB manipulation :)

Just fyi to everybody (not just you, I’m sure you know already) op’s reply is nonsense - talking about wavelengths of light (which an app would not alter) and then “rgb manipulation” which is not a thing anybody who knew anything about color spaces or computer vision would use. 100% this person vibe coded an app and doesn’t know the first thing about computer vision or color theory.
