Packing Pro syncs across iPhone and iPad. I keep my own master packing list, currently about 200 items in 15 categories. Then when Im planning a trip I create a trip-specific list and delete items Im not going to take.
Then as I pack and prepare to depart I check-off items one by one. Without Packing Pro, I would surely forget something!
App is stable and easy to use. I couldnt live without it.
