Momo's Cafe — a restaurant app that builds loyalty

A native iOS app concept built with SwiftUI and Firebase: customer accounts, a live menu, a points-based rewards program, push-notification campaigns, and a clear plan to integrate the Toast POS so online orders reach the kitchen automatically.

The goal

Local cafes lose repeat business when ordering is clunky and there's no reason to come back. Momo's Cafe needed a way to turn one-time visitors into regulars — and to own the customer relationship instead of renting it from third-party delivery apps that take big cuts.

The app was designed as the cafe's own ordering + loyalty hub: fast to use, friendly on the eyes, and built to keep customers coming back with rewards and timely notifications.

What was designed

Key features

Customer accounts

Secure sign-up and login powered by Firebase Authentication. Each customer gets a profile that stores their favorites, order history, saved details, and loyalty balance — so reordering is one tap.

Menu & rewards

A live, categorized menu driven by Firestore so the cafe can update items, prices, and specials instantly. Rewards are baked in: every order earns points, with redeemable perks and featured items front and center.

Push notifications

Planned campaigns via push: "Your free drink is ready to claim," daily specials, slow-hour promos, and win-back nudges for customers who haven't ordered in a while — all timed to drive repeat visits.

Loyalty flows

A points-based loyalty system: earn on every purchase, unlock tiered rewards, birthday perks, and referral bonuses. The goal is a clear, motivating path that keeps regulars engaged and spending.

Integration plan

Toast POS / ordering integration

To make online orders actually useful, the app was planned to connect to the cafe's Toast point-of-sale system through the Toast API. The integration plan covered:

  • Menu sync — pull items, modifiers, and pricing from Toast so the app menu always matches the register.
  • Order injection — send in-app orders straight to the kitchen display / POS, removing manual re-entry and mistakes.
  • Order status — surface preparing / ready states back to the customer.
  • Payments — route payments through the approved processor, with loyalty points awarded on completed orders.
  • Fallback mode — if POS integration isn't available yet, orders route to a staff dashboard / printed ticket so the app still works day one.

Note: Toast API access and partner approval are required for full POS integration; the app was architected so it can launch with a simpler order flow and upgrade to full Toast sync later.
