Ratings and reviews

Already too many adverts and only use it for 30 seconds. Big limited to 8 megapixel cameras means I cannot include fish eyes. Does not work for premacies with multiple different cameras with different resolution

Kept crashing as I was opening any menu options for the first time.

Very good tools but hope you make a version "pay" it out ads thank you.
