Startup Idea: Touch-Sensitive Magnifying App for Text and Images

Startup idea to develop a touch-sensitive magnifying app, enabling users to magnify any text, document or image on touch and revert back when the touch is released. The app should be extremely fast and compatible with text editors especially for programmers who review code on their mobile devices.

app for magnifying text, document, picture or whatever it could be where it is touched get magnified instantly and when touch is left then back to what it was before. obviously this only works with touch screen.

i write code and reviewing lot of them on my phone. i can see them fine but some times and this some times come rather often i am recently noticing. i have to squint to see them. so, it would be nice if it works with lot of text editors. i just point at it and see them bigger and easier to read.

i am cheap and text editors i use are all free apps from google store. i would pay if price is reasonably low.

it will be very fast if it is written in machine code, not in any higher languages like C or C++ or whatever. they multiply 8 to 10 times at least in length of code, wasting time and power.
