What’s that one app on your phone that is utterly invaluable to you specifically. Maybe it’s got a super small use-case, but for you, and you alone it’s absolutely invaluable.
I’ll get us started…
It’s a small all that allows me to stitch photos together. I usually use it to stitch screenshots together. It’s got a nice interface and is absolutely fantastic at the one thing I need it to do.
What about you?
Macrodroid, hands down. Lets you automate almost everything on your phone (and not on your phone), and it’s remarkably friendly to use.
