I keep my org files in dropbox and use beorg on my iphone. Whenever I make changes it immidiately shows up on my phone. I get notifications at scheduled times. I've set it up once and never had to configure anything again. Although I must admit that I only use the app passively to look at my weekly schedule. I haven't used it to make quick captures.
