ForeFlight’s latest release includes Wake Turbulence Alerts.
Pilots can avoid unexpected wake turbulence in flight with the help of visual and auditory alerts, along with a map-based wake depiction system in ForeFlight Mobile, company officials said.
When equipped with a connected ADS-B or FLARM receiver and flying at or above 500 feet AGL, ForeFlight continuously calculates wake effects from nearby aircraft based on their position, altitude, speed, weight category, and winds aloft information, then compares these with your current flight path, ForeFlight officials explained.
“If it determines that an intersection with the wake is likely, ForeFlight issues a prominent visual and audio alert that includes the wake-producing aircraft’s weight category and call sign, and your current distance from the estimated wake location in nautical miles,” company officials continued.
Additionally, ForeFlight depicts the wake’s estimated position and relative altitude directly on the map as a colored ribbon trailing behind the aircraft. Red portions of the ribbon indicate the position of the wake near your current altitude, while light green portions indicate areas where the wake is either above or below you, they said.

The point at which you’ll intersect the wake path based on your current flight path is indicated as a short white strip across the ribbon marked by double chevrons, allowing you to gauge where you’ll cross the wake path relative to the wake itself.
Wake Turbulence Alerts are available with ForeFlight Pro subscriptions and above.

Here, I thought that this was going to be an enhancement for CAT alerts. Wake turbulence is not worth the purchase.
