Why has this idea failed previously? How will your iteration be different?
I'm not naturally a social person but I did go through a phase where I was more social and ended up organizing events. I never thought using texts, whatsapp, etc. to be much of a hassle. I'm also close to a couple of friends that are very social and I've seen them plan and coordinate events. It's never seemed like a hassle and they've never mentioned it as a problem.
Solving your own problem is good advice, but the pitfall is that your own problem may not be one that is shared by many people. I've had to learn this lesson as well. I would run some of my early app ideas by my friends and their response would basically be, "why would I want to do that?" I'm not saying this idea will not work, but definitely talk to the people you're messaging and find out what they think.
Best of luck.
