Disappointing ### 5/5 — Indispensable for accurate artwork *2026-07-25, version 1.5* Many many thanks to the developers. Gets them squared perfectly when askew ### 5/5 — SOOOO very handy! *2026-06-11, version 1.5* I got this app years ago and I still use it all the time. I have never had any issues with it - it is one of my top two or three apps. Awesome! ### 4/5 — Proportions *2026-05-24, version 1.5* So happy to find your app but can we crop too as I am using it to fix up photos of my art which is often square or 800mm x 600mm so it hard to get proportion right. I used to use Microsoft Lens which has now gone ### 1/5 — New updates needed (Not properly functioning) *2026-05-13, version 1.5* White spots in the cutout areas. Please fix it and update it. I will give 5-stars rating after the new update. With Kind Regards ~ ### 5/5 — Game changer for converging lines! *2026-04-24, version 1.5* Has enabled me to quickly clean up unwanted converging lines created while shooting off center (up or down towards the subject). Save some time and watch the YouTube tutorial, it gets you right into editing in no time. ### 5/5 — Straighten yr photos *2026-03-14, version 1.5* AI helped me find this app; my scanning app does the same thing for black-and-white scans but this app is amazing because it lets me rearrange the photo proportions, corner by corner, and keeps my photos as photos. After the tutorial, which took only a few minutes, it was very intuitive. ### 1/5 — No video support *2026-01-24, version 1.5* Do not buy for video ### 1/5 — Not at all user friendly *2025-12-21, version 1.5* When you open this app, you will have absolutely no idea what to do. The 3 clickable buttons are labeled “SKRWT”, “4PNTS”, and “MRRW.” All of those open up your phone photos. Not user-friendly at over. Overly minimalistic to the point of being unusable for the average person. If this app is specifically for a niche group of people, it should have been clearly marketed as such. I want a refund. ### 5/5 — Get it! *2025-12-13, version 1.5* Works perfectly … use the 4 point adjustment a LOT. Fixes those perspective skews so easily. Thank you much! ## Frequently asked questions about SKRWT ### What does the SKRWT app do? SKRWT is a powerful tool for perspective and lens correction in smartphone photography.
