### 1/5 — Absolute waste of money

*2023-08-30*

This app costs $9 U.S. with next to zero capabilities beyond viewing photos beside each other.  Not at all worth the money and if I could get a refund I would.  Absolute trash.

### 5/5 — Does what I need it to do.

*2022-01-19, version 1.4*

This app has worked perfectly fine with the RAW .CR3 files from my Canon M6 Mark ii. I recently switched from Lightroom to Luminar, and from what I can tell Luminar doesn't have a way to compare images side to side. This app really helps with my work flow to compare my pictures right out of camera, deleting bad pictures, which allows me to only move the images I want to edit into Luminar. Highly recommended.
