Just wanted to voice an idea relating to the Jet app.
I think it could be a good idea to have some form of tab under the settings spanner which contains information that helps newcomers understand the platform as well as the rationale behind concepts which are at play, including the C-ratio which is displayed on the top right, a guide of sorts.
Just a brief layman introduction to the basics and concepts in an Investopedia type fashion I think could allow for a greater onboarding of users which are not from traditional finance backgrounds.
Cheers.
