Ditto!

All the superlatives in recent reviews are so well deserved. Every iPhone user could benefit from app to make your iPhone so much more fun and useful. It just needs GPS - no cellular or WiFi signals needed. Last week easily tracked my flight from Atlanta to Sacramento and I could identify the national parks, cites, towns, etc. visible from my window seat. Also continually shows exact altitude and speed of aircraft, etc. Using it walking and hiking is really motivating - can see exactly where you walked and track distance, exact elevation - accurate to 1/100th of a foot in comparison to a surveyors stake I saw on walk yesterday. Buy it and dont look back.
