  The current photometric datasets, that span decades, allow for studying
long-term cycles on active stars. Complementary Ca H&K observations give
information also on the cycles of normal solar-like stars, which have
significantly smaller, and less easily detectable, spots. In the recent years,
high precision space-based observations, for example from the Kepler satellite,
have allowed also to study the sunspot-like spot sizes in other stars. Here I
review what is known about the properties of the cyclic stellar activity in
other stars than our Sun.
