Presbyopia - Magnify

It's frustrating when you can't see nearby places due to presbyopia.
If you just run the app, you can see small letters, etc. with a presbyopia magnifying glass.
This is an app that I made inconvenient for living.
The letters on the medicine box are too small to see, so is there a simple way to see them?
I made this because I thought it would be easy if I use a smartphone.
When you can't see the contract text and need to find your glasses, you can get out of this difficult situation with the smartphone you are holding around you.
Now, don't go looking for a magnifying glass, simply launch the app.
This app is also free.
