High-time-resolution detectors are playing a crucial role in advancing our understanding of neutron stars, enabling precise measurements of their properties. SiFAP2, the high-speed optical photometer permanently mounted at the 3.6m INAF Telescopio Nazionale Galileo, obtained significant breakthroughs in the optical observations of neutron stars discovering optical pulsations of three millisecond pulsars in different luminosity states. Apart from coherent signal searches, SiFAP2 is also involved in multiwavelength campaigns on FRBs to search for optical counterparts. In this talk, I will present groundbreaking discoveries on millisecond pulsars, first results on observations of FRBs and their possible link with magnetars, along with instrumental improvements and exciting future prospects offered by the enhanced e-SiFAP instrument.
