SEAiq apps replace ActiveCaptain with Waterway Guide
Actually, as you can see above, SEAiq lets you overlay both ActiveCaptain and Waterway Guide info onto its chart display (and easily turn either or both overlays on and off). But as noted on the SEAiq website, the AC data will not be updated after May 23, though “We are considering updating SEAiq support for ActiveCaptain but do not have definite plans yet.”
