Everything you need, nothing you don't

Gear Locker

One place for all your gear. Track weight, brand, category, and quantity. Filter and search your entire kit in seconds.

Trip Planning

Create trips, add multiple packs, and organise gear into cubes. See weight breakdowns by base, worn, and consumable — per pack.

Bundles

Group gear that always travels together — shelter system, sleep kit, cook setup. Add a bundle to any pack in one tap.

Gear Catalog

Browse community-curated gear with weights verified from manufacturer specs. Add items directly to your locker.

Packing Checklist

Check items off as you pack. Trip archives freeze your gear snapshot so you always have a record of exactly what you carried.

Works offline

The iOS app queues changes when you're out of signal and syncs automatically when you reconnect. No bars needed on trail.
