What is the best Expo boilerplate for a SaaS mobile app?
It depends on whether you already have a backend. Ignite is a free, well-maintained React Native starter for teams that bring their own server. TurboStarter suits products that pair a mobile app with a browser extension. supastack fits B2B and AI products: its Expo app shares sign-in, workspaces, billing and AI with a supastack web backend, and adds RevenueCat purchases, push notifications, offline access and app lock. The Expo app costs $149 one-time, or $298 together with a web app.
The short answer
A SaaS mobile app is rarely just screens. It needs the same accounts, teams and subscriptions as your web app, plus store purchases and push notifications. The right Expo starter depends on how much of that backend you want included.
- Pick supastack if your mobile app is part of a SaaS product and should share sign-in, workspaces, billing and AI with the web.
- Pick TurboStarter if a browser extension is part of your product alongside web and mobile.
- Pick Ignite if you only need a solid React Native app structure and already have a backend.
What an Expo boilerplate should include
Expo handles the native build, over-the-air tooling and store submission. It does not give you a backend. These are the parts to check before you buy any starter:
| What to check | Why it matters |
|---|---|
| One backend shared with the web app | Two separate backends drift apart and double your security work |
| Tokens kept in secure device storage | A stolen session token is as good as a password |
| Store purchases tied to the same plans as the web | A customer who pays on iPhone must get the same access in the browser |
| Push notifications and deep links | Invites and alerts must open the right screen in the app |
| Offline behavior | Phones lose signal; the app should show recent data instead of a blank screen |
| Build and submit profiles | Store release is where many first launches stall |
Expo boilerplates compared
Here is how the three starters compare. The supastack column comes from its own source code; the others come from the public sources listed below the table.
| supastack | TurboStarter | Ignite | |
|---|---|---|---|
| License | $149 one-time for Expo | One-time | Free and open source |
| Expo version | Expo 57 | Expo 57 | Expo |
| Backend | supastack web app (Next.js or TanStack Start) | Shared with its web app | Bring your own |
| Teams | Workspaces with invites and roles | Organizations with invitations | No |
| Store purchases | RevenueCat | RevenueCat, Superwall | No |
| Other apps | Next.js, TanStack Start, Tauri desktop | Next.js, browser extension | No |
What you get with supastack's Expo app
supastack's mobile app runs on Expo 57, React Native 0.86 and Expo Router for iOS and Android. It talks to the same server as the web app, so a customer's account, workspace and plan follow them across devices. Start with the five-minute quickstart.
- Sign-in with email codes, social accounts and passkeys, with sessions kept in secure device storage.
- Workspace switching, invites and roles that match the web app.
- A paywall backed by RevenueCat, with access checked against the same plans as web billing.
- Push notifications, live updates and deep links that open the right screen.
- An offline cache for recent data and an optional app lock with Face ID, Touch ID or a device passcode.
- An AI assistant and chat that use the workspace's own provider keys and budgets.
- Build profiles for development, preview and production, plus a publishing guide for the App Store and Google Play.
When another starter is the better fit
If your backend already exists, or you are building a mobile-only app with no web product, Ignite gives you a mature React Native structure for free. If a browser extension is core to your product, TurboStarter ships one that shares code with its web and mobile apps.

Common questions about Expo boilerplates
- Does the supastack mobile app work without the web app? — No. It connects to a supastack web backend for sign-in, workspaces and billing. A Mobile-only purchase contains the Expo app but not that server, so most buyers pair it with Next.js or TanStack Start.
- Do I need RevenueCat? — Only if you sell subscriptions inside the app. Apple and Google generally require their own payment systems for digital goods, and RevenueCat connects those purchases to your plans.
- Can I test on a real phone before paying for developer accounts? — Yes. A development build runs on your own device; you need Apple and Google developer accounts only to publish.
- How much does the Expo app cost? — $149 on its own, or $298 with a web app. Any two platforms cost $298, and all four (Next.js, TanStack Start, Expo and Tauri) cost $299. See [pricing](/pricing).
