FltPlan Go on an android tablet/phone is what you’re looking for. VFR sectionals (or Jet Hi/Low, OSM, other charts) with waypoints, approach plates etc you can OVERLAY on the map while flying. It’s a real flight navigation app, but they’ve made it so you can use it with flight Sims.
Tracks your aircraft along the route. It has airport diagrams which you can also use to taxi as it will also track your aircraft on them.
It’s free.
