Have you considered learning how to read musical notes? It's a shame to not take advantage of such a gift.

hum/sing them and record them on the voice recorder app in your phone?

Learning the basics of music theory is not difficult. Go to your local music (not record) store and ask the clerk to select a beginners book for you. You can learn the notes easily and then write down, if nothing else, just the melody. The accompaniment can come later.
