A free day!... I've often wondered what it would be like to have one of those.
Yes, i totally agree with you about Zappl. I think the main problem is only having 240 characters and that includes any tags. The tags should be separate, not counted in with the 240 characters.
I find Steepshot ok for throwing up a photo but it is very laggy on my galaxy S9+. It seems to take forever to publish the post. I don't think it has anything to do with the phone. It was the same on my old Xperia Z5 too. Also, on the Z5, if I try to select tags from the the list that appears, the app crashes and I have to start over. Now i just type my own tags just in case.
To be honest, none of the apps have any business on blockchain, which i think is best only for currency and personal communication, but blockchain is all the buzz at the moment despite poor performance. May as well ride that wave and get all those tokens until people wake up.
