Visolve is the assistive software for people with color vision deficiency, commonly called color blindness. Its PC version has been used by many people around the world, and now this is its iPhone version.

Visolve for iPhone can apply the following transformations, which are same as PC version, to an image newly taken by Camera or being saved in Photo Albums, or a webpage being displayed:
1. Red-Green transform -- transforms redder colors to brighter, and greener colors to darker,
2. Blue-Yellow transform -- transforms bluer colors to brighter, and yellower colors to darker,
3. Saturation increase -- increases the saturation of all colors,
4. Filtering -- darkens all colors other than the specified color, and
5. Hatching -- draws different hatch patterns according to color.

Those transformations help people to distinguish colors, to find a specific color, or to guess a normal color. By using Visolve for iPhone, you can take an image and transform its colors anywhere on the spot when you find a scene or a road sign, etc., which consist of indiscriminable colors.

Additionally, it can simulate the appearance of an image for people with color blindness. By using this feature, people with normal color vision can check how color-blind people see a scene or a caution sign, etc. Note that, however, it should be used only as a guide. We DO NOT guarantee the accuracy of the simulation image generated by Visolve.

this is awesome!
I am colorblind and this app is so useful - I use visolve on my PC at work for confocal micrographs that use a merge to create yellow from a mix of red and green n I couldn't tell the difference between the green n yellow - now I can
On the iPhone I use it because I'm a ham radio operator and now i can identify colors of wires and color coded components

Life Changer

I know "life changer" may sound like an overstatement but I have lived 37 frustrating years not being able to tell when meat was done or whether I was buying green or brown pants. This app fixes all that and really works.
