Unfortunately...

....there is no 6th STAR!

Yepp:
As a Photographer who mainly does Fashion & Architecture i really can say:

The DEV-Team did a perfect Job with SKRWT!!!

As a Photographer who learned his Job with traditional Tools (Plaubel, Hasselblad...) i know how hard it can be to avoid converging lines in Architecture-Photos.

Back then...1970... You had to... But i stop here now to describe it. If YOU are interested in handing Large-Format-Cameras (Plaubel is one of the Best), use Wikipedia.

Back to my ⭐️⭐️⭐️⭐️⭐️⭐️:
SKRWT is (relative) easy to use...but SURE:
one MUST go into physical Details to understand whats it all ABOUT.
Its NO
"One-Click-Funny-Pic"-App

2 come 2 an end:
If you often do Architecture... SKRWT is a MUST!
Its worth its price a 1000%.
IMHO it has the Potential to become "App of the Year".
Amen....
