What about data protection for children’s data?

Take it seriously from the first version, because it is the question that decides the sale. Store the minimum — medical and dietary notes, guardian contacts, nothing else — scope every query so a guardian can only reach their own children, delete trip data on a schedule after the trip ends, and be able to say plainly where the data is hosted. Schools will ask, and a vague answer ends the conversation.

Does the headcount screen need to work offline?

Yes, and it is not optional. The moment you most need a pupil’s allergy note and a parent’s phone number is standing in a field with one bar of signal. Cache the trip roster and the pupil cards on the device when the trip is opened, and queue check-in events to sync later.

How to Build a Field Trip Permission App with AI (2026)

What a field trip permission app needs

Create a trip and send consent requests to the right class
Parents consent in two taps and add medical and dietary notes
Live outstanding list — who has not replied, with a one-tap reminder
Headcount check-in and check-out at each stop
Offline emergency pack: contacts and medical notes cached on the device

The screens

Screen	What it does
Trips	Upcoming trips with consent progress at a glance
Trip Setup	Date, destination, class, cost, staff, and what parents must confirm
Consent Status	Per-pupil consent, outstanding list, and reminders
Headcount	Tap-to-count check-in and check-out per stop
Pupil Card	Medical notes, dietary needs, and emergency contacts — works offline

The data model

School: name, safeguardingContact
ClassGroup: schoolId, name, teacherId
Pupil: classGroupId, name, dateOfBirth, medicalNotes, dietaryNotes
Guardian: pupilId, name, phone, email, isPrimary
Trip: classGroupId, title, destination, departsAt, returnsAt, cost, staffIds, consentQuestions
Consent: tripId, pupilId, guardianId, status, respondedAt, notes
HeadcountEvent: tripId, stopName, pupilId, direction, recordedAt, recordedBy

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 school field trip permission app for teachers and parents. A teacher creates a trip for a class — destination, departure and return times, cost, supervising staff, and any extra questions parents must answer such as swimming ability or photo consent. Parents receive a request, see the trip details, and consent in two taps, adding or confirming medical notes, dietary needs, and an emergency contact number. The teacher sees a live consent screen: how many have replied, who has not, and a one-tap reminder to the outstanding guardians. On the day, a Headcount screen lists the pupils with consent and lets the teacher tap each one to check in at departure and again at each stop, with a running count on screen and an obvious warning if anyone is unaccounted for. Tapping a pupil opens a card with medical notes, dietary needs, and guardian phone numbers, and this data is cached so it works with no signal — that is the whole point of the screen. Screens: Trips, Trip Setup, Consent Status, Headcount, Pupil Card. Needs accounts with two roles, teacher and guardian, and a guardian must only ever see their own children.”

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

Sell to the school, per year, not to parents — roughly $200–600 a year depending on size, bought by an office manager or head rather than a teacher. A parent will not pay for a permission slip and should not be asked to. Expect the sale to be slow and the churn to be near zero, and expect to answer data-protection questions in writing before anyone signs anything.
