The article
Your developer suggests a hybrid app, one codebase for both stores, to save money and time. Someone you trust warns that hybrid apps are slow and feel cheap. Both can be right, because the word covers two different technologies: the old one earned that reputation, and the current one is what a hybrid app development company should be offering you today.
I have spent 18 years in software development, and since 2017 my company, 26 Lines of Code, has grown to 70+ specialists and delivered 150+ projects, Flutter apps in both stores among them. Below: what hybrid means today, when it fits, what sets the price, two apps we shipped and seven questions to put to any hybrid team, mine included.
Hybrid app development services: the short version
| Question | With us |
|---|---|
| What we build | One app for iPhone and Android from one codebase, in Flutter or React Native, with the backend and the admin panel behind it |
| Native code | Swift or Kotlin for any feature that needs the platform directly |
| Releases | The App Store and Google Play; a feature or a fix reaches both stores in the same release |
| Price | A first version for both stores from $5,000; yours gets its own estimate, free, before any contract |
| Fits | Ordering, booking, marketplaces, content and internal business apps |
| Does not fit | Demanding graphics, Bluetooth devices and long background work, where two native apps do better |
"Hybrid" means two different things
Ask which kind you are buying before you compare prices or speed.
- The old kind shows web pages inside an app shell: a website that opens from an icon on the phone. Tools like PhoneGap built these apps.
- The current kind is written once in Flutter or React Native and built into a real iOS app and a real Android app. These frameworks draw app screens directly, with no web page inside.
Hybrid application development services today usually mean the second kind, and it is the kind we build.
In October 2026 I read five company pages from the top of Google for this search. Two of them still offer PhoneGap or Xamarin: Adobe stopped PhoneGap in 2020, and Microsoft ended support for Xamarin on May 1, 2024. Two more never say which framework they would use at all. Five pages are a small sample, but it is reason enough to start with one question to any hybrid mobile app development company: which framework, and is its maker still supporting it?
When one codebase fits, and when it does not
One codebase fits when the screens and the rules are the same on iPhone and Android: ordering, booking, marketplaces, content and internal business apps. Plugins give a Flutter or React Native app the camera, location, push notifications and payments. Where no plugin fits, we write that one feature in Swift or Kotlin and keep the rest shared.
Three questions usually decide it:
- Does a core feature depend on the phone itself? A Bluetooth device, demanding graphics, or long background work such as tracking, syncing or audio points to two native apps.
- Must a custom design look identical on both platforms? That points to Flutter.
- Will your own JavaScript developers look after the app? That points to React Native.
And if the app does not need the stores at all, a progressive web app installs from a link and updates without store review.
Flutter or React Native: how we choose
Both give one codebase for iOS and Android. The difference is who will live with the code and how the app should look.
- React Native is JavaScript with React. It suits teams that already work in them, and it uses each platform's own interface elements, so buttons and menus follow iOS and Android habits.
- Flutter draws every screen itself, so a custom design looks the same on both platforms. Both apps in the work section below are built in Flutter.
You do not have to pick before the first call: we suggest one of the two from your feature list, with the reason.
What our hybrid mobile app development services include
An app is half of a product; the other half runs on a server. We build both:
- The app for iOS and Android from one codebase.
- The backend: the API, the database and the admin panel where your team manages content, orders or users.
- Integrations for payments, messaging and sign-in.
- Swift or Kotlin code for the features that need it.
- The release through App Store and Google Play review, and the updates after launch.
How a hybrid app gets built
- A first call: who the app is for, what it has to do and what it connects to.
- Questions and a rough estimate, both free.
- The agreement: scope, budget and timeline in a contract with our US company.
- Discovery: final requirements, the screen design and the technical approach, settled before the build.
- Sprints and release: every two weeks a demo and a build you install on your own phone; then App Store and Google Play review, support and updates.
Your part is to set the priorities, come to the demos and answer the team's questions. A new request to us gets a reply within 30 minutes on weekdays, 9 am to 6 pm Miami time.
Hybrid app development cost
A first version for both stores starts at $5,000: the smallest version that proves the idea, built with AI tools, reviewed and tested. Your app gets its own estimate, free, in writing, before any contract.
Two things keep that start low. One codebase means each feature is written once, not twice. And on every task a person works in a pair with AI, so the routine goes fast while the decisions stay with people. We do not train AI on our clients' code: our AI agents carry the practices my team has settled on over the years. More on where AI actually speeds up a build.
What sets the rest of the price:
- the screens and the user roles;
- integrations: payments, messaging, sign-in;
- the admin panel behind the app;
- live features such as chat, calls or video;
- features that need Swift or Kotlin code;
- more than one language.
None of the five pages I read says where its own price starts. Every price we publish is on our pricing page.
Two hybrid apps we shipped
- Mutualz: a restaurant app with two sides. A start-up from Oldenburg, Germany: diners order and pay at the table, collect points and share their visits, and restaurants manage menus, orders and offers in an admin panel. It is built in Flutter on Node.js and AWS and is live on the App Store and Google Play in German and English. The hard part was losing nothing on the way: orders, points and user activity are tracked end to end between the app, the restaurant and the backend.
- Tarot Fans: one app for two roles. Clients and tarot experts share one Flutter app with a Django backend: live sessions, audio and video calls billed by the minute, chat, a shop of readings and a wallet. The hard parts were real time on every channel, each with its own price per minute, and money moving both ways, with Stripe under the wallet. The app is live on Google Play.
What to ask a hybrid app development company before you sign
Seven questions, and they work on any vendor. Forward the table to whoever will sign the contract on your side.
| Ask | A good answer | A red flag |
|---|---|---|
| Which framework, and is it still supported? | Flutter or React Native, named in the estimate | PhoneGap, Xamarin, or no name at all |
| Does the app draw its own screens? | Yes, it is a real app on both platforms | "We wrap your website in an app" |
| What if a feature has no plugin? | Swift or Kotlin for that feature, priced in the estimate | "Anything is possible", with no plan |
| Who builds the backend and the admin panel? | It is in the scope, with the stack named | "The app connects to your API", which nobody has built |
| Whose accounts will publish the app? | Developer accounts registered to your company | The developer's own account |
| When is the code ours? | Once it is paid for | "The code stays with us" |
| What will we see before launch? | A build on your own phone every two weeks | Screenshots at the end |
Our answers are in the middle column. The accounts row is advice for any vendor: the developer accounts and the signing keys decide who can update the app later, and the article on mobile app maintenance shows how to check yours.
What you own
The code written for your app is yours once it is paid for. When clients ask me who owns the code, my answer is short: whoever paid for it. Keep the app's developer accounts in your company's name as well, and you can change teams later without starting over.
Next to hybrid apps
An iPhone-only app is iOS app development, and an Android-only one is Android app development; everything we build for phones is under mobile app development. If you need Flutter developers inside your own team rather than a whole project, that is staff augmentation.
Send us the feature list. We suggest Flutter or React Native and put a rough price on it, free and before any contract.
