Capturing notes or ideas has been so difficult on the fly. I have even tried third part apps like http://captio.co/

Doing this process you will be able to enable the quick Notes icon to your iPhone or iPad’s Control Center so you won’t even have to fuss with unlocking your device in order to scribble down a quick thought. You can set your device to automatically pull up the last note you were working on, if you’d rather edit a larger, running list than create a new note each time you tap the button.
To get started, tap on your Settings app and pull up the Control Center. Tap on Customize Controls, scroll down a bit, and tap on the plus sign next to Notes to add it to your Control Center.
Next, you’ll want to stay in your Settings app, but head back to the primary screen and scroll down until you see the Notes app. Tap on that to access its settings. Scroll down until you see the option to “Access Notes from Lock Screen,” and tap on that.
From there, you’ll get one of two options to pick from. Choose wisely:
Also, note that you get a number of specific options to adjust if you select “Resume Last Note,” including how long your device should wait before creating a brand-new note—an important security feature, in case someone gets their hands on your device.
Once you’ve finished setting up the Notes app, you’ll now be able to swipe down from the upper-right corner of your iPhone or iPad—whether it’s locked or not—and tap the Notes icon to begin writing down your thoughts. The interface is the exact same as Apple’s regular Notes app with one small modification: You won’t be able to access the rest of your iPhone or iPad’s notes unless you authenticate into your device.
If you’re on an iPad and you happen to have an Apple Pencil, you can also activate your screen and tap twice with the Pencil to automatically pull up Instant Notes—no Control Center shortcut required
