iOS and Android apps
Apps built in Flutter or React Native from one codebase, or in Swift and Kotlin when native performance is needed.
iPhone and Android apps designed, built and published for US businesses and startups, with one team handling design, code, the back end and store submission.
United States, served remotely from Pune, India
Quavento Technologies develops mobile apps for businesses and startups in the United States. Our team in Pune, India, handles the whole job: product planning, interface design, iOS and Android development, the server side, testing and getting the app approved on the App Store and Google Play. You see a working build on your own phone every two weeks.
An app is a bigger commitment than a website. It has to be approved by Apple and Google, updated when new phones and operating systems arrive, and good enough that people keep it installed. Most apps that fail do not fail on code. They fail because they solved a problem nobody had, or because the first version tried to do everything.
This page covers how to decide whether you need an app at all, how to choose between native and cross-platform development, what Apple and Google charge and require, and how the process runs with a remote team.

A mobile app earns its cost when people use it often, when it needs phone features, or when it must work without a connection. Booking a class three times a week, tracking a delivery, scanning a barcode on a warehouse floor and receiving a time-sensitive alert are app jobs. Reading about your services once before calling you is not.
A responsive website or a progressive web app covers many needs at a fraction of the cost. It needs no store approval and updates instantly. We build those too, and we will recommend one when it fits. See progressive web app development.
A simple test helps. Would a customer open this at least once a week? Would they give it space on their home screen? If the honest answer is no, start with the web and revisit the app later.
The United States is unusual among large markets because the iPhone holds roughly half of smartphone use or more, and a higher share among younger and higher-income users. In many other countries Android dominates. A US consumer app that launches on Android only will miss a large part of its audience.
For most US projects the answer is both platforms from the start, built with a cross-platform framework so the cost is closer to one app than two. If the budget only stretches to one, your audience decides. A product for field workers whose employer issues Android devices should start on Android. A consumer lifestyle app usually starts on iOS.
We look at who your users are, not at averages, before recommending a path.
Cross-platform frameworks such as Flutter and React Native let one team write most of the code once and ship to both iOS and Android. For the great majority of business apps, including booking, ecommerce, content, social features and dashboards, the result is indistinguishable from native to the user, and it costs less to build and maintain.
Native development in Swift for iOS and Kotlin for Android is the better choice when the app leans heavily on device capabilities: advanced camera work, augmented reality, demanding graphics, complex background processing or the newest platform features on launch day.
The decision is not permanent. A cross-platform app can include native modules for the one or two features that need them.
To publish on the App Store you need an Apple Developer Program membership, which costs $99 a year. Google Play charges a one-time $25 registration fee. Both accounts should be opened in your company's name, not ours, so that you own the listing and the customer relationships.
Both stores take a commission on digital goods and subscriptions sold inside the app. The standard rate is 30 percent, reduced to 15 percent for developers who qualify for Apple's Small Business Program or on the first $1 million of annual revenue on Google Play. Physical goods and real-world services, such as a shirt or a haircut, are not subject to the commission and can be charged through a processor such as Stripe.
Each store also reviews apps before publishing. Apple in particular rejects apps that crash, that are thin wrappers around a website, that hide features from review or that lack a way to delete an account. We design with the guidelines in mind so review is a formality, and we handle any questions the reviewers raise.
Apple requires a privacy label on every listing that states what data the app collects and why, and Google Play has a similar data safety section. If the app tracks users across other companies' apps and websites for advertising, Apple's App Tracking Transparency rules require an explicit permission prompt.
US law adds more depending on the audience. Apps directed at children under 13 fall under COPPA and need verifiable parental consent before collecting personal information. Health apps that handle patient data for a provider or insurer fall under HIPAA. California and several other states give residents rights to see and delete their data.
We keep data collection to what the app needs, document it accurately for the stores and build account deletion and data export features. Legal interpretation belongs to your attorney, and we build to their guidance.
We map the core journey first: the few screens a user passes through to get the main job done. Those are drawn as wireframes and joined into a clickable prototype you can run on your phone. Putting that prototype in front of five real users reveals most of the confusing parts before any code exists, when changes are cheap.
Visual design follows platform conventions. iPhone users expect navigation and gestures to behave as they do in Apple's apps, and Android users expect Material Design patterns. An app that ignores those habits feels foreign, however attractive it is. Accessibility is part of the design: text that scales, sufficient contrast and labels for screen readers.
For a deeper look at how we approach interfaces, see our UI/UX design page.
Almost every app needs a back end: a server that stores accounts and data, enforces rules, sends notifications and talks to other systems. It is invisible to users and decides whether the app is reliable and secure.
We build back ends with Node.js or Python and PostgreSQL, or with a managed platform such as Firebase or Supabase when speed to market matters more than flexibility. Hosting sits in your own AWS, Google Cloud or Azure account in a US region. An admin panel lets your staff manage users and content without asking a developer.
If the app must connect to an existing system, such as a booking engine, a point-of-sale system or a CRM, that integration is scoped early, because it is where schedules most often slip. Our custom software development page covers this work.
Launch is the beginning of the bill, not the end. Apple and Google release new operating system versions every year, and apps must be updated to stay compatible and remain in the stores. Third-party libraries need security updates. Servers, databases, push notification services and analytics all carry monthly charges that grow with usage.
Then there is the product itself. Reviews, usage data and support requests will show what users want next. Apps that keep improving keep their users, and apps that are abandoned collect one-star reviews.
Plan a yearly maintenance budget from the start. We offer a monthly plan that covers monitoring, compatibility updates and a set number of development hours, and our article on app development cost explains what drives the numbers.
Publishing an app does not bring users by itself. The App Store and Google Play hold millions of apps, and most downloads go to those that people search for by name or that rank for a clear need. App store optimization is the work of making your listing easy to find and persuasive once found.
The title and subtitle should say what the app does in the words people type. Screenshots should show the main benefit in the first two frames, since most visitors never scroll further. Ratings matter a great deal, so we add a polite in-app prompt that asks for a rating after a successful action, never after an error. A short preview video helps for apps whose value is easier to show than to describe.
We prepare the listing, localize it where you serve Spanish-speaking users, and review search terms and conversion in each store's analytics after launch.

Release, crash and usage monitoring, and a roadmap for the next version based on real behavior.
A first release is quoted as a fixed price in US dollars against a written scope and paid in milestones: design, each development phase and launch. The price depends on the number of screens, the platforms, the complexity of the back end and the integrations required. Store fees, cloud hosting and third-party services are paid by you directly to those providers. After launch, maintenance and new features run on a monthly plan or a dedicated team. Developer accounts, source code and cloud infrastructure are all in your company's name from the first day.
Our team works from Pune, India. We do not have a US office, so every project is run remotely with a named project manager, a weekly call and written updates. These are the hours we keep for calls with US clients.
| US time zone | Examples | Call window |
|---|---|---|
| Eastern (ET) | New York, Florida, Georgia, North Carolina | 9 am to 1 pm ET |
| Central (CT) | Texas, Illinois, Tennessee | 8 am to 11 am CT |
| Mountain (MT) | Colorado, Utah, Arizona | 8 am to 10 am MT |
| Pacific (PT) | California, Washington, Oregon | 8 am to 9 am PT, or 5 pm to 7 pm PT |
A focused first version usually takes four to six months from discovery to store launch. Simple apps can be quicker, and apps with complex back ends or several integrations take longer. Apple and Google review typically adds a few days.
Yes. Flutter and React Native produce apps for both platforms from a largely shared codebase, and for most business apps users cannot tell the difference. Features that need deep device access can be written natively and added to the same app.
You do. The Apple and Google developer accounts are opened in your company name, the code lives in your repository and the servers run in your cloud account. We work as invited users you can remove.
We design and build to the App Store Review Guidelines, which makes approval very likely, but Apple makes the final decision. If the reviewers raise an issue, we fix it and resubmit as part of the project.
Only on digital goods and subscriptions sold inside the app, and many smaller developers qualify for a 15 percent rate. Sales of physical products and real-world services are not subject to the commission.
Usually. We start with a code review to assess quality, dependencies and documentation, then tell you whether it is better to continue with the existing code or rebuild parts of it.
You receive builds through TestFlight on iPhone and through Google Play internal testing on Android. You install them like any other app and send feedback straight from your phone.
