Food logging app advice

I am so excited to take my first 2.5 dose today! I have been lurking and preparing so much that I feel like I am prepared as much as I can be.

I know not everyone logs food, but I feel like this will help me especially in the beginning. Does anyone have any preference between FatSecret, Chronometer, or another app? I am mostly wanting to be sure I am eating enough protein, fiber, etc.
