Mobile App Development Services
Pick the platform strategy before you pick a price.
Four ways we build. Choose one to see the stack, the trade-offs and what it buys you.
React Native app development for one codebase, two stores.
1 codebase
iOS + Android
Our largest practice. A single TypeScript codebase compiled to native iOS and Android, with native modules written by us wherever the JS bridge is not enough — payments, background location, BLE, camera pipelines. Best value when you need both platforms and one roadmap.
- 40–55% lower build cost than two native apps
- Over-the-air updates for non-native fixes
- Shared design system across both platforms

Straight Answers
Cost, timeline, ownership.
No rate cards or hidden phases. Four decisions every product owner has to make, answered directly.
How much does mobile app development cost in India?
A focused MVP typically lands between $8,000 and $20,000, a production app with payments, roles and an admin panel between $20,000 and $50,000, and a multi-module platform above that. React Native app development usually costs 40–55% less than building two separate native apps. ACSIUS quotes a fixed range against a written scope after a free consultation, and prices any change before building it.
How long does it take to build a mobile app?
Discovery and UI/UX take 2–3 weeks, an MVP build 8–12 weeks, and a full-feature app 4–6 months including QA and store review. You see an installable build every week from the second sprint, so progress is something you can hold in your hand rather than read in a status report.
Should I choose React Native or native development?
Choose React Native when you need both platforms on one roadmap and your features are mostly UI, data and payments — most marketplace, booking, fintech dashboard and content apps qualify. Choose native Swift or Kotlin when the app depends on heavy graphics, deep OS integration, wearables or sustained background hardware access. We recommend the cheaper option whenever it genuinely fits.
Do I own the source code and app store accounts?
Yes. Code lives in your repository from the first commit, apps are published under your Apple and Google developer accounts, and all design files and credentials transfer to you on payment. There is no lock-in to ACSIUS for future work.

Full product build
From $20k
Both platforms, backend, admin dashboard, payments, notifications, QA lab coverage and store launch under your developer accounts.
- Best for
- Funded startups and SMBs
- Timeline
- 4–6 months
Dedicated app team
Monthly
Hire mobile engineers, a designer and QA as an embedded pod in your standups, sprints and repo — scale up or down each month.

- Timeline
- From 1 month
How We Build
Idea to store listing in six phases.
Every phase ships something you can open, click or install. No hidden gates.
- 01Week 1–2
Discovery & scope
Workshops on users, jobs-to-be-done and must-have vs nice-to-have. You leave with a feature list, a platform recommendation and a fixed cost range.
Scope doc + estimate
- 02Week 2–4
UX flows & prototype
Clickable prototype of the core journeys before any code, tested with 3–5 real users so we fix flow problems while they are still cheap.
Figma prototype
- 03Week 4–5
UI design system
Screens, components, states, empty states and motion specs — a system your future developers can extend instead of redrawing.
Design system
- 04Week 5–14
Sprint engineering
Two-week sprints across app and backend, with an installable TestFlight or Play internal build at the end of each one.
Weekly builds
- 05Rolling
QA & device lab
Functional, regression, performance and security passes on 20+ real devices, plus crash and ANR budgets agreed before release.
Test reports
- 06Launch +30d
Store launch & growth
Store listings, screenshots, review responses, staged rollout, crash monitoring and a 30-day post-launch support window.
Live on both stores
Milestone invoicing, weekly builds, and your repo from the first commit.

Crash gate
Store-ready, not demo-ready
We handle Apple and Google submission, policy forms, screenshots and review replies. Store review and listing updates managed by us until you are live.
Weekly installable builds
From sprint two you install the real app on your own phone every week. Progress you can tap beats a status report you have to trust.
Real-device QA lab
20+ physical iOS and Android devices, including low-RAM handsets and throttled networks, because emulators hide the bugs your users find.
Your repo, your accounts
Code in your Git from the first commit, apps under your developer accounts, credentials and design files handed over on payment.
Backend and analytics included
APIs, admin dashboard, event tracking and crash monitoring are part of the build — not a surprise phase after launch.
We stay after launch
30 days of free post-launch support, then optional care plans covering OS updates, store policy changes and iteration sprints.

FAQs
Mobile app development, answered.
Send us your idea, a competitor app or your existing codebase and we'll tell you what we would build, on which platform, and what it costs.
Talk to an App LeadSixteen years of delivery, an in-house salaried team of 40+ designers and engineers in New Delhi, 180+ apps live on the App Store and Play Store, and a working method built on weekly installable builds instead of monthly slide decks. We also publish under your developer accounts and hand over source code, so our track record has to stand on its own rather than on lock-in.
Both. React Native is our largest practice because one TypeScript codebase serving iOS and Android usually cuts 40–55% of the cost, and we write native modules in Swift or Kotlin whenever a feature needs them. When an app depends on heavy graphics, wearables or sustained background hardware access, we recommend native Swift or Kotlin instead.
An MVP typically runs $8,000–$20,000, a production app with payments, roles and an admin panel $20,000–$50,000, and larger platforms more. After a free consultation you get a written scope with a fixed range, milestone-based invoicing and change requests priced before they are built.
Yes. We prepare listings, screenshots, privacy and data-safety declarations, then submit and manage review under your Apple Developer and Google Play accounts. If you do not have accounts yet we walk your team through creating them, since ownership should stay with you.
Frequently. We start with a code and architecture audit, then send a prioritised list of fixes, risks and effort estimates. Work continues on a branch with CI so your live app keeps running while we stabilise it.
Secure token auth with refresh rotation, encrypted local storage, certificate pinning where warranted, least-privilege backend roles, no secrets in the bundle, and audit logging on sensitive actions. We sign NDAs before code access and can align delivery with HIPAA or GDPR requirements when your sector needs it.
Every project includes 30 days of free post-launch support. After that, care plans cover iOS and Android OS updates, store policy changes, dependency upgrades, crash triage and a monthly change report, with iteration sprints when you want new features.
You do. Code sits in your repository from the first commit, and source code, design files, credentials and store assets transfer to you on payment. There is no licence fee and no obligation to keep working with us.
