Which programs do you actually use in your calculator?

The calculator I use all the time is the HP-71B in diverse emulated forms (running on a PC, a tablet and a phone), complete with Math ROM, JPC ROM, HP-IL ROM and plenty of RAM, more than enough to have many programs instantly available, about 100+, some of them quite big.

The ones I use the most are my MINIMAX polynomial fit program (which will fit an Nth-degree polynomial minimizing the absolute errors [not the "sum-of-squared-errors"]), my IDENTIFY constant-recognition program (v2.0), and several very specific work-related programs, as all things having to do with solving polynomials, non-linear equations, integrating functions, dealing with matrices, complex numbers, Fourier transforms and number-theory functions are already taken care of by the MATH and JPC ROMs.

Very occasionally I also use an HP-15C and some SHARP pocket computers but I don't keep programs permanently stored there, I write them on the go.
