Pack Pal brings the food part of a backpacking trip into one clear plan.

A backpacking trip has plenty of moving parts. Food planning often means switching between meal ideas, daily totals, and a separate packing list.
Pack Pal is being built to bring those pieces together: plan trail days, choose meals, review daily calorie totals, and check your food as you pack.
It is an iPhone app from Talon 5 Labs, currently preparing for launch. The screens on this website show sample trips and meal data.
