It's easy to use, simple application that you can build your workflow in minutes! I love how it is so customizable as well - there are many ways one could be able to create their own workflows or even add-ons if necessary (i would like some more advanced options).
In my experience this tool has been very reliable when working remotely from home which makes me feel comfortable about being productive while building out our business operations without having any physical presence of employees within an office environment. Honestly haven't found anything yet but i do believe they will improve upon what we have already created once things get rolling towards launch date later next year. We built all aspects of internal communication into it including email notifications/emails sent through different channels(phone calls), text messages & WhatsApp groups etc..
