Perfect except for one thing

Would be perfect if there were more than just 3 levels of zoom. Ideally it would be better to allow any zoom level - by dragging a corner or whatever.

App hasn’t been updated in awhile, but since it works as advertised with no issues, it hasn’t really needed any updates.

To the developer, I hope you’ve not abandoned this app.

Consistently never updated...

Bought this and works fine for iPhone 7 comparisons. For iPhone 7 plus though, you cannot resize the uber layer to match the screen simulator. It’s either 50%, 100%, or 200%, none of which will match it.

It needs a way to drag/resize, and because ot that, giving it a 1 star. Looking for another tool

Exactly what I was looking for

I tried another app “Overlay” first and it’s missing key features that Uberlayer has - most importatnly ability to control the scale of the overlay image. I was looking for a way to compare Mobile design concepts (comps) to actual working App screens to see if layout was correct etc. This works perfectly for this and other scenarios I have in mind.
