Abstract: We index the class of quasiconformal circles by $ k$ between zero and one such that $ k = 0$ corresponds to arbitrary Jordan curves and $ k = 1$ to circles. We establish an estimate depending on $ k$ for harmonic measure in a domain bounded by a quasiconformal circle. Applications of this estimate are made to boundary correspondence under conformal maps, Hardy class of certain functions and a Phragmén-Lindelöf theorem.
