Should a tip tracker connect to the POS or payroll system?

Not in the first version. Integrations differ for every restaurant and most workers cannot get API access. Manual entry that takes ten seconds is reliable everywhere, and card tips can be copied from the end-of-shift receipt.

Can the app tell users how much tax they owe on tips?

Keep it to records and totals. Tax rules on tips vary by country and change often, so estimating what someone owes is risky. A clean export that the user or their accountant can work from is the useful, safe feature.

How to Build a Tip Tracker App with AI (2026)

What a tip tracker app needs

Log a shift with hours, cash tips, card tips, and tip-out
Effective hourly rate per shift including base wage
Best days and shifts ranked by earnings per hour
Weekly and monthly totals with a simple chart
CSV export of all shifts for tax records

The screens

Screen	What it does
Shifts	Recent shifts with total earned and hourly rate
Log Shift	Job, date, start and end time, cash, card, tip-out, notes
Insights	Best weekday and shift type by hourly earnings
Totals	Week, month, and year totals with a bar chart
Jobs	Workplaces with base hourly wage and default tip-out percent

The data model

Job: name, baseWage, defaultTipOutPercent, colour
Shift: jobId, date, startAt, endAt, cashTips, cardTips, tipOut, shiftType (lunch, dinner, late, delivery), notes
Settings: currency, weekStartsOn

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 tip tracker app for servers, bartenders, and delivery drivers. Shifts lists recent shifts newest first, each showing the job, date, total earned (base wage times hours plus cash and card tips minus tip-out), and effective hourly rate. Log Shift is built for speed after a long night: pick the job from chips, date defaults to today, start and end time pickers, number inputs for cash tips, card tips, and tip-out (pre-filled from the job default percent), shift type chips, and optional notes; save in one tap. Insights ranks weekdays and shift types by average earnings per hour so the user can see which shifts are worth taking, and hides any ranking with fewer than three shifts behind it. Totals shows week, month, and year totals with a bar chart and a separate cash tips total, since cash is what people forget to report. Jobs manages workplaces with base wage and default tip-out percent. Export all shifts as CSV. Store everything on the device; no account needed. Screens: Shifts, Log Shift, Insights, Totals, Jobs.”

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 one-time unlock or a small annual subscription for insights, multiple jobs, and CSV export, with logging free forever. Tipped workers are price sensitive and skeptical of subscriptions, so a cheap lifetime option usually converts better than a monthly plan. The honest pitch is tax season: a year of clean records is worth far more than the price.
