This was created by Mike Vacanti because he felt that he was looking all around for an app that had good qualities to it, but couldn't find one that he liked. You can see his post HERE about the release of his app. I really like what he's doing in the industry and think that he's a great resource as well. He believe the Myfitnesspal calculations to be crappy just like I do.
JMeter includes all the functionality you need to test an API, plus some extra features that can enhance your API testing efforts. For example, JMeter can automatically work with CSV files, which lets your teams quickly create unique parameter values for your API tests. It also integrates with Jenkins, which means you can include your API tests in your CI pipelines.
Using a drag and drop interface, automated processes are designed to follow existing processes or improve on them. In most cases, the process is documented using a process modeling tool and then reviewed by all stakeholders for accuracy. Once the static design is approved, work begins by designing the actual process including forms, tasks, recipients, alerts/notifications, etc. This is done using workflow automation software that includes pre-built tasks (complete form, submit approval, hand-off to another person, etc.) that can be arranged sequentially or in parallel.
