PACKSTACK: GEAR LISTS & PACK WEIGHT TRACKING FOR BACKPACKERS Packstack is the gear list and pack weight app built for backpackers, hikers, and ultralight gram-counters. Build your gear closet once, spin up a packing list for any trip in minutes, and know your base weight before you hit the trail. Looking for a LighterPack alternative with a real mobile app? This is it. GEAR CLOSET All your gear in one searchable place. Log brand, product, weight, price, and category for every item — or skip the typing and pull verified specs from the gear catalog. Wishlist the gear you want but don't own yet. GEAR RESEARCH Browse thousands of outdoor products by category, sorted lightest to heaviest. Compare any product against the category median, dig into full specs, and add it to your gear closet in one tap. PACKING LISTS Build a list for each trip by pulling from your gear closet. Everything stays organized by category — shelter, sleep system, cookware, clothing — with total, base, and worn weight at a glance. Build multiple packs per trip to compare loadouts. CHECKLIST MODE When it's time to pack, flip any list into a checklist and tick items off as they go into the pack. Nothing gets left behind. WEIGHT TRACKING Automatic totals for pack weight, base weight (everything minus consumables), and worn weight. Switch between imperial (oz/lb) and metric (g/kg) anytime — every number updates instantly. SMART TRIP DETAILS Type a trail name and Packstack researches the rest: distance, elevation gain, terrain, and expected temperatures for your dates. It only fills in what you haven't set yourself — your local knowledge always wins. CALORIE CALCULATOR (PACKSTACK PRO) Estimate daily calories from your trip's distance, elevation, terrain, pace, and temperature — combined with your hiker profile. Take the guesswork out of food planning and know exactly how much to carry. HIKER PROFILES Set up profiles with height, weight, age, sex, and body type. Assign a profile to any pack for personalized calorie estimates — perfect for couples, families, or group trips.

Your first kit is free; Packstack Pro unlocks unlimited kits. SHARE YOUR SETUP Every packing list gets a public link anyone can view on the web, no account required — perfect for shakedown feedback. Or export a trip summary card with your weight breakdown, sized for Instagram Stories. IMPORT & EXPORT Switching tools? Import from LighterPack or any CSV in seconds.
