If you want to design effective funnels, this is THE tool you need to have. It's well thought out and for the price, it's a steal. Other competitors like UXpressia have various limitations even on paid plans but not this. I like that it's simple and intuitive enough with minimal learning curve.
If you are new to customer journey mapping and worry that you may not be able to use the tool efficiently, don't worry. The CXDeployer team has a 100 page Customer Journey Mapping 101 eBook to get you started quick and easy. There's no hard and fast rule. When all's said and done, it's just a tool to help you plan and visualize; with the added ability to allow you and your team to keep coming back to it and improve upon the existing plan after you've gotten some real world data. Love it~
