It is easy to use as it integrates with slack very well so that all your communication can be done from one place without having separate apps or accounts installed.
This app has not been updated since 2017 but I think there are better options out now like Asana integration where we have more features than this simple tool allows us too easily integrate into our daily lives while working remotely. Integrates perfectly with slacks notification system allowing me to quickly respond directly through my notifications page rather then emailing someone back via slack itself when they send over an issue needing attention.
