Is a packing list app too small to be a real product?

As a generic checklist, yes — the App Store has hundreds. As a specific one it works: ski trips with families, cabin crew, festival packing, and travelling with an infant all have real list complexity and an audience that will pay once. Pick the niche before you pick the features.

Does it need to work offline?

Absolutely — this is the offline case. People finish packing in a hotel room on roaming, or check bags at a gate with no signal. Store lists on the device and treat any sync as an optional extra, not a requirement for the app to open.

How to Build a Packing List App with AI (2026)

What a packing list app needs

Reusable templates per trip type — beach, ski, work, camping
Quantities that scale with trip length
Per-person lists for family trips
Check-off that survives being offline on the way to the airport
Categories: clothes, toiletries, documents, tech
"Did not use" flag after the trip to slim the next list

The screens

Screen	What it does
Trips	Upcoming and past trips with packed progress
Trip Detail	Grouped checklist with per-person tabs and progress bar
New Trip	Name, dates, template, travellers — generates the list
Templates	Create and edit reusable lists with per-day quantities
Post-Trip Review	Mark unused items so the template improves each time

The data model

Trip: name, startDate, endDate, templateId, travellers
Template: name, tripType
TemplateItem: templateId, name, category, quantityPerDay, fixedQuantity
PackItem: tripId, personName, name, category, quantity, isPacked, wasUsed

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

“A packing list app. Users create a trip with dates and pick a template (beach, ski, work, camping), and the app generates a checklist where quantities scale with trip length — three days means three shirts, but one toothbrush regardless. Family trips get a list per traveller with tabs. The checklist groups by category and checking items off works fully offline. After the trip, a review screen lets the user flag items they never used so the template gets leaner next time. Screens: Trips, Trip Detail (grouped checklist, per-person tabs, progress), New Trip, Templates, Post-Trip Review. Works offline.”

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

One-time purchase ($3–5) fits the usage pattern better than a subscription — people pack a handful of times a year and resent a recurring charge for it. If you prefer recurring, gate per-person lists and unlimited templates, not the core checklist.
