How do you keep your recipes?

I want to start logging my own recipes that I find that I enjoy, rather than attempting by memory, or following an online one. I have began writing them down in my notepad on my phone, but I feel I need a better way to do this . It will either be copied and pasted into a word document and printed on paper, or I may use an app. (I have no researched apps that would do this yet)

But again, the question is how do you do it? What are tips to keep it nice and organized?

Additionally, feel free to share one of your favorite recipes from your recipe book! I absolutely love making new dishes for the family to enjoy.
