TO-DO apps visibility

As different contributors attempt to add different to this repository one of the issues will be plagiarism and mostly inadvertently. What if at the bottom of the landing page (README.md) we have a table that has the structure given below and strives to provide a one-line explanation of what each of the apps does. This table will be updated by the respective authors when they submit PRs and the review process will start here.

All potential contributors will start here to get an idea of where gaps are. In addition, any new users looking to implement similar work for their personal projects will know where to look.
