I agree with Jay...do not use Armour All on the leather. There is however, a leather cleaner/conditioner from the Armour All brand that I've been using. It comes in a brown bottle and I've been using it for a long time now. The seats in my car still look new except for the drivers seat....which after 201,143 miles doesn't look bad at all. It'* a little worn but no cracks or splits. The key is to keep leather clean so that dirt and debris don't tear into it and to keep it conditioned so that it doesn't dry out on you and thereby crack. Only really need to use the product 2-3 times a year (more if left out in the baking sun a lot) and that'* about it. You'll be surprised at how much dirt actually comes off the seats when you clean them!
