In no particular order, I like to try free apps, but of course most come with a free, limited version with premium features that can be upgraded for a price. Here's what I use, and none of these are paid partners, or sponsors. Just the ones that I use, and how they are useful for me. Hope this helps you figure out which ones will work for you, but I encourage you to try some out, and use the ones you like.
