Spinelio was a school software including features like student management, attendance, grades, exams, timetables, etc. It was designed to be used by private schools. It was used as a private MVP from a couple of schools but never released to the public.
I was the co-architect and developer of the Spinelio application. We released the MVP version in under three months. Eventually, we decided to suspend the development of the application due to a lack of interest from the market and a lack of funding.
