How to build a restaurant app.
The owner’s 2026 guide.
This is the actual workflow on how to build a restaurant app: the features that matter on day one, the build path with an AI app builder, the Stripe and Toast POS integrations, and what it really costs. Written for a restaurant owner who has heard of DoorDash commissions and wants their own ordering app for restaurants instead of renting one. If you have been Googling how to make a restaurant app and landing on agency pitches, this is the cheaper version.

What it is
What people mean by “how to build a restaurant app”.
When a restaurant owner searches for how to build a restaurant app, they are not asking how to write Swift code. They want a branded mobile app on the App Store and Google Play that lets regulars place an order, earn loyalty points, and get a push when the food is ready. The app sits next to the existing POS, not on top of it, and the customer never has to open DoorDash again to get a $14 burrito.
In 2026, the practical path is an AI app builder that generates a real React Native codebase, plus Stripe for payments and OneSignal for push notifications. Menu data lives in Supabase so the owner edits prices from a phone. The AI does the wiring; you describe the restaurant. The output is your code, your app, your customers.
The features
The eight features a restaurant mobile app actually needs.
Forget the AR menu and the in-app chatbot. The ordering app for restaurants that wins is the one that gets a hungry customer from menu to checkout in three taps. These eight features cover 95% of orders.
Menu management
Photos, prices, modifiers, and 86'd items. The owner edits menu management from a phone between services. Menu data lives in Supabase so a price change updates every device in seconds.
Online ordering & cart
Takeout, delivery, or dine-in. Online ordering handles modifiers (no onion, extra cheese), tip presets, scheduled orders for later pickup, and a guest checkout path that does not force a sign-up.
Payments
Stripe handles the card. Apple Pay and Google Pay are one-tap, which raises conversion on mobile by around 30%. Tips, taxes, and surcharges are line items the kitchen ticket prints clearly.
Push notifications
OneSignal sends order-status pings (Your pickup is ready) and promo blasts (Tuesday tacos $2 off, 6 to 9 p.m.). Push notifications routinely beat email open rates four to one for restaurants.
Loyalty punch card
Buy 9 burritos, get the 10th free. The loyalty card lives in the app, not in a stamp book. Loyalty members come back 2 to 3 times more often than walk-ins on average.
Table reservations
If you take reservations, a calendar view replaces phone tag. Confirmation push goes out automatically; a reminder push fires two hours before the seating. Skip this entirely if you are takeout-only.
POS integration
Toast POS, Square, or Lightspeed. The app pulls menu items and prices from one source of truth and writes orders back as kitchen tickets, so servers and the app stay in sync.
Order status tracking
A simple progress bar: received, in the kitchen, ready for pickup, out for delivery. The status updates push to the customer's phone. No one calls the front-of-house asking where their food is.
Skip these in v1.
- AR menu previews (cool, no one uses them)
- In-app chatbot (drives support tickets, not orders)
- Native gift cards (Stripe Issuing later, not now)
- Crypto payment (no one is asking)
The workflow
Five steps from idea to a live food ordering app.
This is restaurant app development the practical way. Each step below is one or two prompts to Newly, the AI restaurant app builder used in the example. The path is the same on other AI builders that output real code.
- 1
Describe the restaurant app in your own language
Open the AI app builder and type a paragraph: cuisine, locations, whether you do delivery, your POS, and which loyalty mechanic you want. The AI uses that to scaffold the menu screens, cart, checkout, and admin panel in one pass.
- 2
Connect Stripe and OneSignal
Stripe handles payments, OneSignal handles push notifications. The AI builder writes both integrations from your API keys. Apple Pay and Google Pay light up automatically once your Stripe account is verified.
- 3
Wire the menu to Supabase
Menu data lives in Supabase so you can edit prices and 86 items from your phone without redeploying the app. The AI app builder generates the admin screen the manager actually uses behind the bar.
- 4
Add Toast POS or Square (optional)
If you already run Toast POS or Square, one prompt to the AI hooks the order endpoint to your POS so the kitchen printer gets the ticket. Skip this step for the v1 if you do not run a POS yet — orders can just email to the kitchen.
- 5
Test on a real phone, then publish
Scan a QR code with Expo Go to load the app on a real iPhone or Android. Place a $0.50 test order, watch it print. When the loop works, the AI builder ships signed binaries to TestFlight and Google Play internal testing in about 20 minutes.
Real restaurant app cost from scratch.
The real numbers for one location, year one. No agency markup, no SaaS lock-in.
- Newly subscription
- $25/mo
- Apple Developer Program
- $99/year
- Google Play Developer fee
- $25 one-time
- Stripe processing
- 2.9% + 30¢ per order
- OneSignal push
- Free up to 10k subs
- Supabase (menu data)
- Free up to 50k rows
For a one-location restaurant doing 200 mobile orders a month, year-one total lands under $1,200 all-in. Compare that to a Toast online ordering plan that runs $800 to $2,000 a year per location and gives you a generic page on their domain.
Build or rent
When to use Toast and when to build your own.
Hosted SaaS like Toast or Square Online is the right answer for some restaurants, and the wrong answer for others. The honest version, not the sales pitch.
Pick a hosted SaaS when…
- You run one location and just need takeout orders
- You already pay for Toast POS hardware
- You do not care about branded loyalty mechanics
- Push notification revenue is not part of the plan
- You do not want to manage Apple and Google submissions
Build your own restaurant app when…
- You serve regulars who would download a branded app
- Loyalty is a real revenue lever (coffee, juice, taco shops)
- You want phone numbers and push opt-ins, not just emails
- You plan to open a second or third location and reuse the app
- You want to cut DoorDash commissions on direct-order regulars
AI restaurant app builder
Example: Newly
- Output
- Real React Native + Expo codebase you own
- Cost
- From $25/mo + Stripe fees
- Time to ship
- 2 to 5 days
Verdict. Best for an owner who wants a branded app, loyalty mechanics, and full control of the customer data. The code is yours, so you can hand it to a developer later without rewriting.
Hosted SaaS
Example: Toast, Square Online, ChowNow
- Output
- Ordering page on their domain
- Cost
- $69 to $165/mo per location + hardware
- Time to ship
- 1 to 3 days
Verdict. Best for one location that just needs a working online ordering page tied to the POS. You rent it, you do not own it, and your customers see a Toast URL, not your brand.
Custom dev agency
Example: Local React Native shop
- Output
- Native iOS + Android + admin
- Cost
- $30,000 to $120,000 upfront
- Time to ship
- 3 to 6 months
Verdict. Best for a 10+ location group with unusual loyalty rules and a budget for ongoing maintenance. Overkill for a single restaurant. The agency owns the code if you do not negotiate carefully.
The owner who searches for how to build a restaurant app almost always lands on path one or path two. The agency path makes sense for groups of 10+ locations. For a single shop, the AI restaurant app builder route is faster, cheaper, and the code is yours to keep if you ever switch tools.
FAQ
Frequently asked questions.
For a restaurant app with menu management, online ordering, loyalty, and push notifications, expect $25 to $80 a month if you use an AI restaurant app builder like Newly. That covers the AI subscription and unlimited cloud builds for iOS and Android. On top of that, you pay $99 a year to Apple, a one-time $25 to Google Play, and standard payment processing fees on Stripe (2.9% + 30¢ per online order). A custom build through an agency runs $30,000 to $120,000 upfront, and a hosted SaaS like Toast charges around $69 to $165 per month per location plus per-device hardware fees. The AI builder route is the cheapest of the three, and the code stays yours.
