I found a nifty app called pipe tool on my Ipod Touch. Although it costs 3.99 it's pretty cool and well worth it. It looks as though it has every pipe tobacco imaginable with photos of the tins, ratings, tin descriptions, as well as an option to set as one of your favorites and notes. The other major feature of this app allows you to keep an inventory. The inventory system allows you to put any notes on tins you want. If you are one of those guys with a huge inventory it allows you to simply search if you are looking for a particular tin in your inventory. I don't know if there is a thread up about this already or if it was made by a member but I figured I would share. Also here are some screen shots.
