Native iOS Apps
Built with Swift and SwiftUI for the performance, privacy, and UX patterns Apple expects. Every app targets App Store submission with proper privacy labels, App Review guidelines, and ASO-optimised metadata.
— App Design & Development
Mobile App Development for iOS, Android & React Native.
Native apps built for the App Store and Play Store — not WebView wrappers. From fintech and e-commerce to on-demand platforms and SaaS companion apps, we handle design, development, backend, and launch as one team.
iOS (Swift)Android (Kotlin)React NativeBackend included
Six categories of mobile app. One team, every platform.
Whether you need a single-platform MVP or a cross-platform production app with a custom backend — we scope, design, and ship it in-house.
Native Android Apps
Kotlin and Jetpack Compose — the modern Android stack. Material Design 3 components, adaptive layouts for phones and tablets, and full Play Store submission with listing optimisation.
React Native Apps
One codebase, both platforms — without the web-wrapper performance trap. We use React Native with Expo and native modules for features that demand platform-level access.
Fintech & Banking Apps
Biometric authentication, encrypted storage, payment gateway integrations, and compliance-aware architecture. Built for the security and reliability standards financial apps demand.
E-commerce Mobile Apps
Product catalogues, smart search, cart management, and checkout flows designed to convert. Integrated with your inventory system, CMS, and payment providers from day one.
On-Demand & Marketplace Apps
Real-time order tracking, multi-vendor management, driver/service provider apps, and notification pipelines — built on scalable pub-sub infrastructure that holds up under load.
— What's Included
Design, development, and launch — all one scope.
No separate design agency. No separate backend vendor. No extra charge for App Store submission. Every project is scoped as a complete deliverable, not a collection of line items.
- Full UI/UX design — wireframes to high-fidelity Figma prototypes
- Cross-device testing on real iOS and Android hardware
- Biometric authentication (Face ID, fingerprint) setup
- Push notification infrastructure (FCM + APNs)
- Crash monitoring and error reporting (Sentry + Crashlytics)
- Firebase Analytics or Mixpanel event tracking
- App Store and Google Play Store submission, listing, and ASO
- API / backend development by the same team
- 30-day post-launch support included as standard
From brief to App Store in 4 defined stages.
Every stage has clear deliverables and requires your sign-off before we proceed — no black-box sprints, no surprises at demo day.
Week 1
Discovery
We map your app's user journeys, review competitor apps, define feature scope, and agree a delivery roadmap — all signed off before design begins.
Weeks 1–3
UX Design
User flow diagrams, low-fidelity wireframes, and high-fidelity Figma prototypes. Interactive prototype handed over for review and approval before development starts.
Weeks 3–14
Development
Two-week sprints with TestFlight / Firebase App Distribution builds every cycle. Automated tests, real-device QA, and performance profiling on each sprint.
Weeks 14–16
Launch
App Store and Play Store submission, ASO optimisation, review management, and a 30-day live monitoring window. Most clients move into ongoing feature sprints from here.

Native Performance, Not Wrappers
We don't wrap a website inside a WebView and call it an app. Every iOS app is built with Swift, every Android app with Kotlin — because Apple and Google users notice the difference.
App Store & Play Store Expertise
We've navigated App Review rejections, privacy nutrition labels, App Tracking Transparency, and Play Store policy updates across dozens of submissions. Your launch won't stall at the gates.
Backend Engineering Included
The API your app relies on isn't outsourced or an afterthought — it's built by the same team, on the same sprint cycle. No integration gaps, no finger-pointing when things break.
Built for Iteration, Not Just Launch
70% of our app clients stay for ongoing feature sprints after v1 ships. We structure every codebase, CI pipeline, and release process to make version 2 faster than version 1.
What Our Clients Say
Our clients praise our dedication, expertise, and results — making us a trusted partner for shipping products that grow their business.
See All TestimonialsExcellent service by Solution World 24×7! Seamless designing!! Very happy to be working with the team!! Thank you!
I had the pleasure of working with Solution World 24×7 for my architectural firm Sunlight Architect's website. I highly recommend Solution World 24×7.
Solution World 24×7 helped us build a modern website that reflects the quality and professionalism of our construction business. The process was smooth and the final result was awesome.
The logo they designed for me was modern, sleek, and professional. It perfectly represented the message and branding. They listened to my ideas and provided valuable suggestions.
Questions about mobile app development.
A React Native app with standard features (auth, profiles, a feed, push notifications) starts around ₹1.5–2.5L. Native iOS or Android apps range ₹2–4L per platform. Full cross-platform apps with a custom backend, admin panel, and complex features run ₹5–15L+. Every project gets a fixed-scope, fixed-price proposal — no hourly surprises.
A mid-complexity React Native app ships in 10–14 weeks from brief to App Store. Simpler single-platform apps can go live in 6–8 weeks. Apps with complex backend systems, real-time features, or third-party hardware integrations typically take 16–24 weeks. We lock timelines in the proposal before starting.
React Native is the right choice for most apps — it ships on both platforms simultaneously, shares ~85% of the codebase, and performs well for the vast majority of use cases. Native makes sense when you need platform-specific APIs (ARKit, HealthKit, complex animations), absolute maximum performance (competitive gaming, real-time video), or are building only one platform first. We'll recommend the right approach in the discovery call based on your specific requirements.
Yes — App Store and Play Store submission is included in every project. We handle certificates, provisioning profiles, App Store Connect setup, Play Console configuration, store listing copy, screenshots, privacy labels, and App Review communications. We have experience resolving App Review rejections and policy issues.
Yes. We build the server, database, and APIs your app talks to as part of the same project scope — not as a separate vendor engagement. Our typical backend stack is Node.js + PostgreSQL deployed on Vercel or AWS, but we'll use what fits your requirements. If you already have a backend, we can integrate against your existing API.
Every sprint produces a TestFlight (iOS) or Firebase App Distribution (Android) build that you can install and test on real devices. Before submission, we run a full QA pass including real-device testing on iPhone SE through Pro Max and Android devices from low-end to flagship, automated UI tests, memory profiling, and crash-free session verification.
Yes — app rebuilds and feature additions are a significant part of our work. We start with a technical audit of the existing app's architecture, performance, and crash logs before proposing what to rebuild vs. refactor. We handle code migrations (Objective-C to Swift, Java to Kotlin) and legacy React Native upgrades.
Both. We work with first-time founders validating an MVP as well as established businesses adding a mobile channel to an existing product. For early-stage startups, we scope aggressively to ship an MVP fast. For enterprises, we focus on reliability, compliance, and integration with existing systems.
