I know what you mean about pressure when any time the phone can ring. I experienced it when Founding a food delivery service and have been on call 18 hours per day. Have never been relaxed when working on the phone. It is so cool that you are going to London for Crypto Show with so many Steemians to meet and talk to.
You might have missed our project development called SteemApp, we have just started and released our first version which is great for posting. Next release will be comfortable to see your feed, upvote and comment. Later on also a lot of cool stuff. Hope you can try it out and support us if you like.
I sure give it a look! Thanks for letting me know!
