iOS and Android apps with a native-feeling interface, smooth performance and publishing on the app stores
Designing an app does not start with drawing screens. It starts with a question: what will users do with this app every day or every week that they cannot do with a website or a messaging app? An app lives on the phone, sends notifications, can use the camera and location, and can work offline. In return, it has to be installed, published in an app store and updated with every new version. If these advantages are not decisive for your business, a web app or a mobile-first website may give you the same result for less — and it is better to know that before you start, not after.
That is why our work at MyTarh is phased and usually starts with an MVP: a version with only the core features that reaches real users sooner and shows which parts deserve more investment. Before the first line of code is written, we define the user stories, wireframes and app architecture, and the full UI design is approved by you. Moving a button at the design stage takes a few minutes; after development it can take days.
We build apps with React Native or Flutter, so a single codebase runs on both Android and iOS, and the interface follows Material Design and Apple’s Human Interface Guidelines. There is one more layer to the decision: how the app reaches its users. Publishing on the App Store and Google Play, with each store’s own review process and rules, affects the choice of platform, the revenue model and even the order in which versions are built. The table further down compares the three main approaches — native, cross-platform and web app.
The type of app is decided before the technology and the price, because each category has different technical needs. Most business apps fall into one of these six categories:
Product catalog, cart, payment and order tracking. If you already have an online store, the app usually connects to the same system so products and stock are not managed in two places. Its main value is repeat purchases and notifications about new offers.
Appointments for clinics and salons, technician requests, class registration. Capacity, time slots and cancellation logic sit at the heart of this app, and it almost always needs a web admin panel so the business can see and manage bookings from the desk as well.
For sales reps, field inspectors or warehouse staff who work outside the office. Offline-first design is critical here: data is recorded without internet and syncs automatically when the connection returns. It usually does not need to be published publicly in an app store.
Courses, videos, articles or audiobooks. The main challenges are protecting paid content, smooth playback on weak connections and choosing a payment model. App stores have their own rules on in-app payments, which need to be checked before design.
For a business that already has a website or software and wants customers to reach their account, orders or records from their phone. Cost depends above all on whether the current system already has an API or one has to be built.
For a startup that does not yet know whether the market will accept its idea. The minimum features needed, on one platform and in one app store, to collect real feedback at the lowest cost — so the next decision is based on user behavior, not guesswork.

The build approach sets the cost and the timeline, and even the route by which the app reaches users. This table compares the three main approaches from a decision-making point of view:
| Criterion | Native (Swift and Kotlin) | Cross-platform (React Native and Flutter) | Web app (PWA) |
|---|---|---|---|
| Main cost driver | Two separate codebases for iOS and Android; every feature is built and tested twice | One shared codebase for both platforms; only device-specific parts need separate work | One web codebase; no separate version per platform and no app store publishing steps |
| Performance and smoothness | Highest; direct access to all operating system features | Close to native for most business apps; a gap may appear with heavy graphics and animation | Depends on the browser; enough for forms, lists and content, limited for heavy processing |
| Build time | Longest; two parallel development tracks | Shorter than native, because most of the code is written once | Shortest, especially if a website or backend already exists |
| Access to phone features | Full | Almost full: camera, location, notifications and offline storage | Limited; more limited on iOS than on Android |
| Publishing and updates | Through the app stores; every new version is reviewed and published again | Through the app stores, like native | No app store; installed by opening a URL, and updates reach everyone instantly |
| When to choose it | Apps with heavy processing, complex graphics or deep hardware dependence | Most sales, booking, service and enterprise apps that are needed on both platforms | Testing an idea, complementing an existing website, or giving iPhone users a simple version without depending on the App Store |
MyTarh’s MVP and Standard packages are built with React Native or Flutter. If reviewing the scope shows that your project would work better with another approach, we tell you clearly before the contract.
The biggest hidden part of an app’s cost is something users never see: the backend. Any app with user login, orders, bookings or editable content needs a server, an API and a panel from which you manage the data. If you already have a website or software with an API, this part is lighter; if not, building it can sometimes take as long as the app itself. After the backend, the factors with the most impact on the estimate are the number of screens and user roles (for example customer, courier and manager), integrations with external services such as payment gateways, maps and SMS, and offline capability with automatic sync.
The second decision is the number of platforms and app stores. The MVP package, at $6,900, covers one platform — iOS or Android — with a simple design and publishing in one app store; it does not include push notifications or advanced analytics. The Standard package, at $12,900, covers both platforms, a custom UI/UX, push notifications, integrated analytics, a web admin panel and publishing on all app stores. Apps with AI, advanced APIs or enterprise security requirements are estimated under the Enterprise package as a custom quote. These figures are a starting point; the final amount is written into the contract after the scope has been reviewed.
Timeline follows the same factors, plus one variable that is in your hands: how quickly decisions are made. Because the work is phased and each stage moves forward with your approval, having content and access ready and giving timely feedback on the design directly moves the delivery date earlier or later. App store review time is outside both our control, so it is wise to leave a margin for it in your launch plan. And remember that an app’s cost does not end at launch: servers, SMS and notification services, and the updates needed when new versions of Android and iOS arrive all have ongoing costs.
This list is the minimum delivery for the project; items that depend on the package are marked. Anything beyond this is written into a separate contract.
Both are strong technologies. React Native suits teams that know JavaScript and has a larger ecosystem. Flutter performs better and is recommended for large projects. We recommend one based on your project needs.
A simple MVP: 30–45 days. A mid-size app: 60–90 days. Complex apps with a back end: 120–180 days.
Free support covers bug fixing and minor updates. To add new features, we sign a separate contract.
Yes. The complete app code is handed over to you in a private repository, and you fully own it.
The MVP package is $6,900 and the Standard package is $12,900; enterprise apps are priced by custom quote. The final amount is set after scoping and written into the contract, because the back end, number of screens, user roles and integrations with other services have the biggest effect on it.
If users come back to your service regularly and need notifications, the camera or offline use, an app is worth it. If use is occasional or you are still testing the idea, a web app is faster and cheaper and does not need to be installed from an app store. In the consultation, we recommend one based on how your users behave.
A clear description of your target users and what they will do in the app, a few sample apps you like, your brand's visual identity (logo and colors) and initial content. If you have a website or software, access to it or its API documentation is also needed. It is best to create the developer accounts on the app stores in your own or your company's name, so you always own the app.
An MVP is a minimum version of the app with only the core features, published on one platform and one app store. Its purpose is to see how real users react before spending the full budget, and to learn which features are worth building. If the architecture is set up correctly from the start, later versions are built on the same foundation instead of starting from scratch.
If the app has user login, orders, bookings or content that changes, yes; that data has to be stored on a server and managed from an admin panel. A web admin panel is included in the Standard package. Server costs are separate from the build cost and change with the number of users and the amount of data.
Usually yes, as long as the website has an API or one can be built for it. Then products, users and orders are managed in one place, and the app and website always stay in sync. Reviewing the current website is part of the initial estimate and directly affects the cost.
Back-end server costs, an SMS service for one-time-code login, a notification service if you use a paid one, and developer account fees on some app stores. In addition, new versions of Android and iOS require app updates from time to time. It is best to plan for these costs from the start.
