Yes, the apple also attracts the earth. But the acceleration of the earth due to this attractive force is negligible because of very small size of the apple i.e.
\[g=\frac{Gm}{R^2}\] where, $m$ and $R$ are the mass and radius of the apple respectively.
The value of gravitational constant $(G)$ is very small i.e. $6.67×10^{-11}$ $\text{Nm}^2/\text{kg}^2$. Since the mass of the apple is also very small, the acceleration $g$ is negligible.
But in the case of earth, it is so massive that $g$ becomes $9.8$ $\text{m/s}^2$ which can be felt by everyone.
