You can’t go wrong with all of the possibilities from Google’s Snapseed. The free app offers several specific controls you usually have to pay for in more advanced editing applications. It’s an easy-to-use option that even amateurs, such as myself, can learn to use. With just a little practice, you’ll be making coarse adjustments to the brightness, contrast, warmth, shadows, and other components of pictures. The app makes clever use of the touch interface. You slide up or down to change parameters, then left or right to adjust it. Then a button at the top lets you quickly view the original image for comparison. Google has also kept a reasonably strong development pace; it’s constantly getting better.
