Another product to consider is Android based Avare. I use it for my real flying, and therefore it’s helpful to use it with MSFS as well.
I wrote a post on how to connect it to MSFS
The only thing I miss out on from Foreflight is the ground altitude along the flight map. But, like the others, it has free access to the actual taxiways and runways and charts, etc., whereas MSFS for whatever reason, chose not to implement real life taxi-maps. I have no idea what they were thinking given the info is freely available. So, in this regard, Little Nav Map shines as it gets its data from the sim.
