This app is designed to simplify the user interface and still make fairly good tone corrections for most photographs.
There are other free apps that I have tried. PhotoPad has some pretty good tools, but I found the app very slow to respond to changes. GIMP is an open-source program that has been around for a long time. However, each time I used it, it would crash after making adjustments, thereby losing all my work. Darktable is another open source project that has many qualities like Adobe Lightroom. It has some nice features, but the learning curve is steep, and there are very minimal tutorials available. Google Picasa used to be available and was a simple editor.
As to FREE available photo editors, the choices are minimal. Many give you free trials, and then want a monthly subscription cost of $5+/month. For $10/month, you can subscribe to Adobe PhotoShop AND Lightroom that will have WAY more features, speed, and reliability.
Affinity Photo is a more advanced level photo editor that has many tools that are associated with Photoshop. The tools respond more quickly and the size of the images you can load can be much larger. This is because it is not hampered by the restrictions of internet speed and browser limitations.
Another advantage in more advanced editors is that you can create "adjustment layers" that can be deleted if you don't like what you see. This is called "non-destructive" editing. Another neat thing about adjustment layers is the ability to "paint" your adjustment onto small parts of the image, and not affect the whole image.
