Gipsi Apps VFR Nav+ is an inexpensive GPS solution using a $5 app, Google Earth and an Android phone or tablet. It even offers voice prompts to keep you on course. Creator/president/cook/bottle washer John Benedict is a GA pilot. I have no connection to this company or product other than thinking it's pretty neat.
