Asematic delivers custom mobile app development services in India for companies launching into India, the US, the UK and the Gulf. Native Swift and Kotlin where it counts, one React Native codebase where it does not, and store compliance handled before you submit.
Release budget
The thresholds every build is measured against, profiled on real mid-range devices.
Getting an app built is the easy part. The hard part is a first session that earns a second one, a cold start users do not notice, and a listing that survives review. This is where projects leak, and what proper mobile app development puts in its place.
What it costs you
An app users open once and delete
We map time-to-value before a screen is drawn, then prime permissions in context rather than at launch. You get an activation funnel you can read cohort by cohort.
What it costs you
Six-second cold starts on a mid-range Android
Baseline profiles, deferred initialisation and lazy dependency graphs keep first paint fast. We measure startup traces on physical mid-range handsets, not the flagship on a developer's desk.
What it costs you
Two rejections before the store lets you in
Privacy manifests, Data Safety declarations and account-deletion flows are built with the app rather than bolted on afterwards. Reviewer notes ship with the first submission, which is what keeps a release out of the rejection queue.
What it costs you
Buried where nobody searching will find you
Title, subtitle and keyword fields are researched against real store search volume. Screenshots and localised metadata are treated as conversion surfaces, because most installs are decided on the listing alone.
What it costs you
Two codebases quietly drifting apart
We choose per feature, not per project. Standard flows share one React Native codebase, while camera, background sync, widgets and anything latency-bound get native modules.
What it costs you
No idea why users churn in week two
The event taxonomy is defined during design, so funnels and retention cohorts are live on launch day. Crash and ANR reports arrive symbolicated, pointing at a real line of code.
Mobile app development is not one job. A consumer product and an offline field tool are different problems — and they get the same release budget, the same accessibility floor and the same store-readiness checklist.
Swift and SwiftUI apps that use the platform properly — widgets, App Clips, Live Activities, background refresh and Keychain-backed security.
Kotlin and Jetpack Compose builds tuned for the device range your users actually carry, with Material 3, WorkManager and Play Integrity handled.
React Native or Flutter where one codebase genuinely serves both stores, with native modules dropped in for the paths that need platform speed.
Offline-first apps for teams working past network coverage: local persistence, conflict-aware sync, device management and role-scoped access.
Storefronts, order tracking and rider or driver apps with payments, push notification journeys and live location built for real logistics load.
Rescuing legacy Objective-C, Java or Cordova apps — incremental rewrite, dependency and OS-target upgrades, with store listings and users carried across intact.
Most agencies pick one and sell it to everyone. We pick per feature, and we will show you the reasoning in discovery before a line of code is written.
Choose when the experience is the product
Full access to the newest frameworks the day Apple ships them, the smoothest animation ceiling and the tightest integration with the hardware.
Choose when device range is the problem
Control over memory, battery and install size across a fragmented device base, and access to background capability iOS does not permit.
Choose when both stores need parity fast
One codebase for standard product surfaces, native modules where latency or hardware demands them, and a single release train for both stores.
These fifteen items are not line-items on a quote. They ship with every app we build, on every engagement model, because an app missing any one of them is an app that will bleed users or fail review.
We pick the app development stack per project, from a short list we know deeply. Nothing is on this page because it trends — each tool is here because it measurably moves startup time, crash rate or the cost of the next release.
Store research happens before wireframes. Onboarding is tested on a real handset before engineering starts. Each stage closes with a named deliverable you review, so you always know what is decided and what is still open.
We tear down the apps already ranking for your category, research store search terms, and settle the platform question with data rather than preference. Output is a scoped build plan and an ASO keyword map.
Deliverables
Every user journey is mapped and turned into a clickable prototype you can hold on a real handset, so navigation and onboarding are tested before engineering starts.
Deliverables
A component library built to each platform's conventions — Human Interface Guidelines on iOS, Material 3 on Android — then applied across every screen state, including empty, loading and error.
Deliverables
The build runs in two-week sprints with backend, payment, push and analytics integrations wired in. Every sprint ends with a TestFlight and internal-testing build you can install.
Deliverables
We prepare both listings, handle review correspondence, ship on a staged rollout, then watch crash-free rate, retention and funnel data and act on what they show.
Deliverables
We do not publish a client portfolio. As a mobile app development company we are new, and a wall of logos we had not earned would tell you nothing you could check. What we can show you is our own software — three products this team designed, built and still runs today, each with a mobile surface people use on a working day.
Campustrue puts attendance, fees and results in the hands of staff and parents on their phones. Beanrow runs floor and kitchen on handhelds where a dropped connection cannot lose an order. Enerixis gives field engineers plant telemetry at sites with patchy coverage. Between them they cover the three problems that break most apps: offline-first sync, role-based access and real-time state.
That is the experience behind the mobile app development work on this page — the same store-readiness checklist, the same release budget, the same accessibility floor. If you would rather interrogate the method than the portfolio, the engineering standard above sets out what every build ships with, the platform comparison shows how we choose native or cross-platform, and the full service index shows where app development sits beside the rest of what we do.
Built and operated in-house
Every build runs on one of three models: a fixed-price project, a monthly retainer, or a dedicated team. The scope decides which one fits, not a package you have to pick before anyone understands the work. Most clients start with a fixed-price project and move to a retainer once the app is in both stores.
A defined app with a launch window
We scope the app during discovery, write the specification, and quote a single figure against it. That figure does not move unless you change the scope, and any change is priced before it starts. The right model when the feature set is settled and you want the budget agreed before a line of code is written.
A live app that has to keep shipping
A fixed block of design and engineering each month, spent on new features, OS-version upgrades, experiments and performance work. Priorities are agreed with you at the start of every sprint rather than fixed a year ahead. This is how most apps run once they are in both stores.
A roadmap that needs its own crew
A dedicated team — iOS, Android and backend engineers, a designer and a delivery lead — assigned to your roadmap full time. They work inside your repository, your stand-ups and your release process, as an extension of your team rather than an agency at arm's length. Suited to a roadmap long enough to justify permanent capacity.
Not sure which model fits? Describe the problem rather than the solution. We will tell you which platform the app actually needs, how the build is best structured, what it will cost against a written specification, and when the honest answer is that you do not need an app at all.
The questions buyers actually ask before commissioning mobile app development work, with real answers rather than a sales line.
Cost tracks feature depth and platform count rather than screen count. A single-platform MVP sits in a very different bracket to a two-platform app with offline sync, payments and an admin backend, because the engineering and QA surface differ. We scope in discovery and quote a fixed figure against a written specification, so there is no open-ended billing.
A production app typically runs about twelve weeks: one week of discovery and store research, two weeks of flows and prototyping, two weeks of design, six weeks of engineering, and a final week for submission and staged rollout. Cross-platform builds compress the middle; apps with offline sync, live tracking or heavy integrations extend it.
It depends on what the app does. Choose native Swift or Kotlin when the interface is the product, when you need the newest platform frameworks immediately, or when camera, background processing and latency matter. Choose React Native or Flutter when both stores need parity quickly and most screens are standard product surfaces. We usually mix the two — shared code for ordinary flows, native modules for the demanding paths — and we recommend the split in discovery rather than selling you a default.
Yes. We prepare both listings, write and localise the metadata, produce the screenshot sequences, file the privacy manifests and Data Safety declarations, and handle correspondence with reviewers through the approval process. Release goes out as a staged rollout with a kill switch, so an unexpected problem can be contained without an emergency resubmission.
Yes. Most apps need an API, a database and a place for your team to manage content, users and orders. We build that alongside the app on Node.js with PostgreSQL, or on Firebase where real-time sync and speed to market matter more, and hand over an admin panel your staff can actually operate.
Where it should, yes. Offline-first is a design decision made early, not patched on later. We persist data locally, queue writes, and resolve conflicts on reconnect with rules agreed with you — which is essential for field, logistics and sales apps working past reliable coverage, and useful for almost every app on Indian mobile networks.
Yes. iOS and Android ship major versions every year, and both stores enforce minimum SDK targets that will eventually block updates if ignored. Post-launch cover includes OS and SDK upgrades, dependency patching, crash and ANR triage, store policy changes and performance monitoring — as a maintenance plan, or as a product retainer that also funds new features.
You do. The repository, the source code, the designs and the credentials are yours, and the apps are published under your own Apple Developer and Google Play accounts rather than ours — so your listing, reviews and install base stay with you regardless of who maintains the app later. We hand over documentation and a walkthrough at the end of every engagement.
Mobile app development is where users spend their attention. What feeds the app and what it feeds decide whether the build pays for itself. These are the pieces that usually sit either side of it.
