Nice app idea. I set up a slack reminder to do the same, so there is a need and a problem to be solved.
I wouldn’t pay for this but something to think about is an organisation might because they should want to know what their staff have achieved. Otherwise all they have to go on is completed tasks - which we all know isn’t everything. There is value in gap fillers.
A org focused product would be great especially if it was rounded with 1-1 and performance review stuff. products like that already sell which is a good sign.
