yes! this app does what is intended to do and does it very well! tested other like gimbse for live correction, not as good fast or accurate. it also is much faster than likes of snapseed, vsco, lightroom for perspective correction, and seem to give you good accurate results with one click. I also tested with added wide angle lens and with photos from my dslr / mirrorless and really it does work well. highly recommended.
I wish that you can retain location information which seem to be lost. I also wish there is some similar tool to automatically et accurately straighten photos taken from a side angle. Finally it does occasionally bug or freeze and i just restart. Anyway very minor drawbacks, if you like to take architectural photos, this is a must and your money is well spent.
