I am no expert. Just the noob that started this thread. I believe with Little Nav Map you do all your planning in the app. Then you can open a web browser afterword’s. It does have chart following. I have not really looked into the Web or tablet part of it yet.
Volanta (which does the same thing as Sim Tool Kit Pro) runs in a tablet browser or an app on your PC, both have Chart following. Not sure if STKPro runs on a tablet. Hopefully the flight sim Pro’s out there can explain some of the differences between all these apps…
