Pack once.
Reuse forever.

Modulist turns your packing routine into reusable modules — dive kit, camera bag, week of clothes — that snap together into a checklist for every trip. Set the trip length and quantities do the math themselves.

Cave trip — Mexico

5 days
0 of 6 packed

DRY SUIT — COLD WATER

CLOTHING

↑ This one works — change the days, check things off.

How it works

Three steps, and the third one is the fun part.

STEP 1

Build modules once

A module is a block of gear you pack together — “camera kit”, “toiletries”, “cold-water dive gear”. Add items with fixed counts or per-day quantities.

STEP 2

Snap a trip together

New trip, new list: pick the modules that apply, add any one-off items, drag things into whatever order you pack them.

STEP 3

Set the days, pack, check off

Tell the list how long the trip is and per-day quantities recalculate instantly. Then check items off and watch the progress bar fill.

Small app, sharp edges

Everything a packing list needs and nothing it doesn’t.

Quantities that think

“1 shirt per day”, “1 pod per 3 days” — trip length changes, counts follow.

Lists with structure

Modules become collapsible groups. Nest items, drag to reorder or re-parent.

Everywhere you are

Your next trip packs itself

Well — almost. You still have to fold things.
