A few things are possible if you tap on a graph: you could pick data, drag a finger from one point to another to obtain differences and slope. There is a linear fit in “More tools”, however, it is not (yet) possible to select a different data range.
The math tools inside phyphox, see https://phyphox.org/wiki/index.php/Phyphox_file_format, are rather powerful, so you could build your suggestions into new menu entries that you share with your students. We hope that a new editor is ready soon(ish) that facilitates creating such experiments.
(Ad additional math tools: there are pros and cons. It makes sense that students use the same apps from the math courses and quite some work reasonably well also on smartphones – and, personally, I am a fan of the “there's an app for that” approach: a set of powerful, yet simple apps being good at their one thing.)
