Mobile App Development
Cross-platform mobile apps that users actually love to use
We build high-performance iOS and Android applications using React Native and Flutter. From concept to App Store — UI/UX design, development, QA, and submission handled end to end.

Our mobile app development service is the right fit when your situation looks like one of these:
Businesses with a service or product that needs a dedicated mobile experience — not just a responsive website, but a proper native-feeling app
Companies extending an existing web platform to mobile, needing API integration, push notifications, and native UX patterns
Founders building mobile-first consumer or B2B apps who need end-to-end delivery including App Store and Play Store submission
How We Work
A defined process is what separates predictable delivery from chaotic projects. Here is exactly what working with us looks like.
- 1
User Research & Information Architecture
We map your core user journeys before any design work begins — identifying the screens that matter and cutting the ones that don't. Most mobile apps fail from feature overload, not feature gaps.
- 2
UI Design & Interactive Prototype
Full UI design in Figma with a clickable prototype for stakeholder sign-off. You experience the exact look and feel of the app before a single line of code is written, catching design issues when they cost hours — not weeks.
- 3
Sprint Development
Feature-by-feature builds using React Native or Flutter, with TestFlight (iOS) and internal Play Store (Android) builds delivered every two weeks. You test on real devices throughout — not at the end.
- 4
Device Testing & QA
Tested across iOS and Android on real devices, covering edge cases, offline behavior, slow network conditions, and performance under load. Simulator testing alone misses real-world issues.
- 5
Store Submission & Launch
We handle App Store Connect and Google Play Console setup, screenshots, metadata, privacy policy requirements, and the review communication process — including drafting responses to rejection reasons, which most agencies leave to you.

Why LOTS Tech for Mobile Apps
There are many agencies offering mobile app development. Here is what is specifically different about how we work.
- —
UI/UX design is in-house, not outsourced — your designer and developer work on the same team from day one, eliminating handoff gaps that produce beautiful mockups and clunky implementations
- —
Cross-platform by default — one codebase for both iOS and Android reduces build cost by 40–60% and ensures both platforms stay in sync on every update
- —
We manage App Store rejections — Apple rejects a significant percentage of first submissions. We handle the response and resubmission process as part of every project
Frequently Asked Questions
- Do you build native or cross-platform apps?
- We build cross-platform apps with React Native or Flutter, which deliver near-native performance at a fraction of the cost of maintaining separate iOS and Android codebases.
- Can you redesign an existing app?
- Yes. We handle full redesigns, performance overhauls, and feature additions to existing mobile apps across all frameworks.
- What is your app submission process?
- We manage the full submission process including App Store Connect setup, Google Play Console configuration, screenshot creation, metadata, and review communications.
- Can you add features to an app we already have?
- Yes. We work with existing React Native and Flutter codebases for feature additions, UI overhauls, and performance improvements. We do a code audit first to assess the health of the existing codebase and give you an honest assessment before committing to a scope.
- Do you set up analytics and push notifications?
- Yes. Push notification infrastructure (Firebase Cloud Messaging / APNs), in-app analytics (Mixpanel, Amplitude, or Firebase Analytics), and crash reporting (Sentry) are included in all production app builds as standard — not charged separately.
