Great post. I have been looking at a lot of applications and have been iffy in using them because they are asking for the private master keys instead of just the posting key.
I have been using busy.org and zappl. Will try the others from this list.
Thank you so much for highlighting these apps and their subsequent creators.
Yea, as far as I know, they are using SteemConnect and it's safe to use. But I am the same way, I don't like to use my active key or master password. You may want to look into SteemConnect more and decide for yourself if it's safe to use.
