As well as not wanting to spend all my time on my phone, I also want to take the time to write out quality responses. I've had enough of people getting annoyed at my slow replies as if I owe them a fast response.
To combat this, I made a chat Web App where chat messages get delivered at the pace of real life letters. On top of that, there's no annoying notifications or other annoying bloat.
Have a look, and if you want to reach out to me on the app my username is snailchat.
