Anyone know of an app/widget to quickly toggle magnification gestures?

[M Class]

I have some vision issues and magnification gestures makes using many apps quite pleasant for me, but it makes other apps act up so I can't just leave it on all the time. Is there any way to easily toggle it on and off?

Would like to know this too! I have tried tasker but it's not the best solution

Is there not a widget built in for this? I thought there was.
