Awesome! I prefer pen & paper when I don't have a phone on me. I have found that just having the Capture Wallet reassures me that “no thought” will get lost in the ether. Haha!
On phone, I use Todoist. NirvanaHQ is great but I just can't stick with it for more than a few days. No matter how many apps I try, I always come back to Todoist.
