Roundtrip Packing List

Every packing list forgets you the moment you land. This one keeps the bag. Pick your luggage and it fills as you tick things off — carry-on, checked bag, rucksack, whatever you're taking. Each packed thing drops into the case and settles where it fits, so one glance tells you how full you are and what is still out. Then it does the part a checklist cannot. Because the bag still knows what went into it, the journey home is a sweep of the room rather than a list. Bedside, for the charger plugged in behind it. Bathroom, for the hook on the door. Wardrobe and drawers, for the one nobody opens twice. Safe and pockets, for the passport you hid carefully. Anything you cannot find is written onto that trip's tag — so the next trip with that bag opens with a warning instead of a surprise. • Your bags fill as you pack — see what is in each at a glance • A room-by-room sweep on the way home, grouped by where things actually hide • Whatever gets left behind is recorded on that trip's tag • Make each bag yours: name, kind, size and any colour you like • Kits that add the obvious things — documents, tech, washbag, clothes No account, no ads, no server. Everything stays on your phone. Free for 7 days, then one payment — roughly a coffee — and Roundtrip is yours for good. Made by one person who kept leaving chargers in hotel rooms.
