Personally I am a big fan of Adobe Lightroom. It is a monthly subscription but, I like how I can edit photos on my PC at home, as well as on my phone.
They have a bunch of other plans but I prefer the Lightroom since that's all I need myself. It's about $10.50 a month [after taxes].
One of the things I love about Lightroom is all the presets. Adobe has a nice selection of free ones, and then there are so many people out there who well sell presets that others can use as well.
Hope I at least helped a little. Congrats on your tablet, and good luck!
