Love and Use Every Day

We design and build iOS and Android apps, in Swift and Kotlin or in React Native and Flutter, and pick the approach that suits your product rather than our habits. We start from who will use the app and what they need in the first minute, then build something quick to open, easy to learn, and structured so your team can keep adding to it. From a first MVP to an app with a custom backend and payments, we stay with you through the store release.

We deliver iOS and Android products using React Native, Flutter, Swift, and Kotlin, choosing the stack from your product requirements rather than a house preference. Every project covers offline-first architecture, engagement features such as push notifications and deep links, app store preparation, and secure API integration. What ships is quick to open, safe with user data, and ready to grow from the first release to millions of users.

Capabilities

Key Capabilities

Concrete capabilities we bring to this engagement — not buzzwords.

Cross-Platform Delivery

Shared React Native or Flutter codebases when speed and consistency matter most, and native code when a product needs the platform’s full power.

Native-Grade Performance

Smooth animation, efficient long lists, and platform conventions that feel at home on iOS and Android, profiled on real mid-range phones.

Offline-First Architecture

Local storage, a sync strategy, and graceful behaviour when the signal drops, so people can keep working on a train or in a lift.

Engagement & Deep Links

Push, in-app messages, and deep links designed to bring people back with something useful, not a stream of notifications.

MVP & Store Launch

A focused first release in 6-10 weeks, plus store listings, privacy disclosures, and review handling taken care of for you.

Security & PDPA-Aware Data

Secure sign-in, encrypted storage, consent screens, and account deletion built in from the first version.

FAQ

Straight answers about how we build mobile apps.

Both. We build native apps in Swift and Kotlin, and cross-platform apps in React Native and Flutter. We recommend an approach per product based on performance needs, team plans, and budget, not on a house preference. A trading app with heavy animation and camera access usually goes native. A content or e-commerce app with a small team usually ships faster and cheaper in React Native or Flutter, with no noticeable difference in UX.

Swift and Kotlin for native work, React Native with Expo and Flutter for cross-platform, Firebase for common backend needs such as sign-in, push, and analytics, and full App Store and Google Play release management. We also mix per feature: a native module can sit inside a React Native app for the one screen that truly needs raw hardware performance.

Yes. We audit the codebase first, looking at dependency health, crash rates, architecture, and technical debt, and then agree a plan to steady your releases and improve the app step by step, whether we built it or someone else did. We say so plainly if a rewrite would cost less than patching a fragile codebase, but we default to gradual improvement wherever possible.

It depends on scope, but most first releases take a few months from kickoff. An MVP usually takes 6-10 weeks and a full-featured app 3-6 months. We start with discovery and design and then build in 2-week sprints, so you are testing real builds on a real phone within the first few weeks.

Cost depends mostly on feature count, number of platforms, and backend complexity. A focused MVP on one platform typically starts in the low-to-mid six figures (THB). A full-featured app on iOS and Android with a custom backend, payments, and offline support usually costs several times that. We quote a fixed price per phase after discovery, so there is no open-ended hourly bill.

Yes. We manage the whole release: screenshots, listing copy, privacy policy and data-use disclosures, age ratings, and the review submission. If a store rejects a build, which happens even to experienced teams, we find the guideline involved and resubmit. This is part of the launch phase, not a surprise extra.

For apps where it matters, we design offline-first from the start: key data is stored on the device, actions queue and sync automatically when the signal returns, and the screen degrades gracefully instead of showing an empty error page. We scope this during discovery, because it changes both the architecture and the testing plan.

You do, entirely. Source code, design files, and ownership of the store accounts pass to you on final payment. We recommend building and submitting under your own Apple Developer and Google Play accounts from day one, so you have full control and visibility the moment the app goes live and no dependency on us to keep it running.

We design for PDPA from the first sprint: collecting only the data the app needs, showing clear consent screens in Thai, allowing users to delete their account and data, and protecting data in storage and in transit. For a formal compliance review we can involve our PDPA compliance service.

A short description of the idea or problem, who will use the app, any existing designs or systems it must connect to, and a rough deadline. A rough idea is enough. The discovery session turns it into a scope, a timeline, and a platform recommendation.
