I use ForeFlight and Xavion.
ForeFlight is what I use most of the time. Xavion is primarily used as a tool for engine failure.
Xavion was created by Austin Meyer, who created the Xplane 11 flight simulator. He's an aeronautical engineer and a pilot. The biggest feature of Xavion that I love is the red EMER button.
Xavion is constantly running simulations of power-off glides from your current position to every runway that it thinks is within gliding range. It picks what it considers the best destination and shows you a series of "hoops" to fly through.
Xavion asks you for specific glide data for your airplane. A fast, slow and configured glide speed. It uses these three speeds and descent gradients to land you at the optimum point on the best runway. The touchdown location is calculated like a glide pilot does it:
This is a potential life saver with engine failure in IMC or night.
Xavion is $10/month and includes updated charts in the subscription price.

- Runway length minus your landing distance = extra runway amount
- Extra runway amount divided by two
- Add extra runway amount to the threshold
