Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Nice points but I disagree with the having too much music theory isn’t going to help me make simple songs. There is no such thing as having too much music theory because it is just that .. theory. It not like when you sit down at a piano and play you are thinking, I need to add that super locrian scale in this part to make this piece smarter. People in fact should spend more time on learning music theory (regardless of level) and they might improve their music however simple it maybe be and I include myself obviously.
Both? Not sure I understand what you're asking.
Might actually go with a Radial Key Largo - not as sexy as a new synth or FX pedal, but it's practical - 3 stereo input mixer, USB audio interface, sustain/volume pedal input, FX send/return, etc.
