GearQM started with a familiar problem: the same generic list, printed off again, that doesn’t know you’re going above 3,000 m in shoulder season, that the hut serves dinner, or that you already own a hardshell you don’t need to buy twice.

So we built a rule engine instead of a list. Eighty-four items across thirteen categories, each one declaring when it applies, how important it is, and which variant fits the conditions. Point it at a trip and it reasons the same way an experienced partner would — then swaps in your own gear and tells you what it weighs.
