Can the app calculate taxes for a household employee?

It should not try in version one. Household employment tax rules differ by country and, in the US, by state, and mistakes have real consequences. Show gross hours and pay, export the records, and point families to a payroll service or accountant.

How do I stop disputes over edited hours?

Never let an edit overwrite silently. Store who changed a shift, when, and why, and show the change history to both parent and caregiver. Transparency is the whole value of a shared record — both sides need to trust the same numbers.

How to Build a Nanny Hours Tracker App with AI (2026)

What a nanny hours app needs

Clock in and out with one tap, with edits that both sides can see
Hourly rate, overtime threshold, and extra-child rate
Daily log for parents: meals, naps, activities, notes
Weekly summary of hours and gross pay
Mileage and expense entries for reimbursement

The screens

Screen	What it does
Today	Clock in or out, current shift timer, and the daily log
Daily Log	Meals, naps, activities, and a note for the parents
Week	Shifts per day, total hours, overtime, and gross pay
Expenses	Mileage and reimbursable purchases with receipt photos
Settings	Rates, overtime rule, and who is connected

The data model

Household: name, hourlyRate, overtimeAfterHours, overtimeMultiplier, currency
Member: householdId, userId, role (parent, caregiver)
Shift: householdId, caregiverId, startedAt, endedAt, editedBy, editNote
LogEntry: shiftId, type (meal, nap, activity, note), time, text
Expense: householdId, caregiverId, date, kind (mileage, purchase), amount, receiptUri, status

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 shared nanny hours tracker used by a family and their nanny, each on their own phone. The family creates the household and invites the nanny with a code; parents and the caregiver see the same data. Today lets the caregiver clock in and out with one large button and shows a running timer. Any edit to a shift after the fact records who changed it and a short note, visible to both sides, so there are no silent changes. Daily Log lets the caregiver quickly add meals, naps with start and end times, activities, and a free note, which parents can read during the day. Week shows each shift, total hours, hours over the overtime threshold set in Settings, and the gross amount owed at the hourly rate and overtime multiplier, with a clear label that this is a gross estimate and not tax or payroll advice. Expenses records mileage and reimbursable purchases with a receipt photo, and parents mark them approved or paid. Settings holds the rate, overtime rule, and connected members. Screens: Today, Daily Log, Week, Expenses, Settings.”

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

A modest family subscription works — the household saves an awkward weekly conversation and has records if there is ever a dispute. The bigger opportunity is nanny payroll and tax filing, but that is regulated and varies by country and state; partner with a payroll provider rather than building it, and keep the app clearly on the record-keeping side.
