This magnify APP is not good, it only lets you zoom in X4 and to zoom in higher you have to buy the PRO version. I found others out there that are much better free ones like loupe and magnify glass 2018 to name a few.
I little advice for the makers.. when your starting a app that there is a bunch already and the ones out are free you need to make the app your going to make public 200% better then what’s out there for people to notice your APP, add different features ex: add a color changing screen, add text to pic, add pic to the pic make different themes etc etc ....
Just my small two cents, no shade ......😉
