Whatboard.app alternatives

We just recently started using Sortd in our office. I work a hybrid schedule currently due to some medical issues. This program helps keep my co-workers up to date on what I am working on. It has helped me be more organized as well, and keeps things in front of me, helping to keep things from "slipping through the cracks". Being able to share an email, without having to forward it, it amazing. Can't wait to see what they add next.
