  We review the modular flavor symmetric models of quarks and leptons focusing
on our works. We present some flavor models of quarks and leptons by using
finite modular groups and discuss the phenomenological implications. The
modular flavor symmetry gives interesting phenomena at the fixed point of
modulus. As a representative, we show the successful texture structure at the
fixed point $\tau = \omega$. We also study CP violation, which occurs through
the modulus stabilization. Finally, we study SMEFT with modular flavor symmetry
by including higher dimensional operators.
