  In this paper we show that, besides the usual calculus involving K\"ahler
differentials, it is also possible to define conical calculus on schemes and
perfectoid spaces; this can be done via a stratification process. Following
some ideas from [1-2], we consider some natural stratifications of these spaces
and then we build upon the work of Ayala, Francis, and Tanaka [3] (see also
[4-5] and [18]); using their definitions of derivatives, smoothness and vector
fields for stratified spaces, and thanks to some particular methods, we are
able to transport these concepts to schemes and perfectoid spaces. This also
allows us to define conical differential forms and the conical de Rham complex.
At the end, we compare this approach with the usual one, noting that it is a
useful \textit{addition} to K\"ahler method.
