Mobile apps for iOS and Android, published in the stores
Native or cross-platform based on your problem, not the trend. A dedicated team in Monterrey + Texas, code 100% yours from the first commit, and a working build in your hands every 2 weeks — not a black box until launch.
We design, build and publish mobile apps for iOS and Android.
We go native (Swift / Kotlin) when you need maximum performance or deep hardware access, or cross-platform (Flutter / React Native / Expo) when a single codebase reaching both platforms gives you the best balance of cost and time-to-market. We cover the full cycle: strategy, design respecting Apple and Google guidelines, integration with your existing APIs and systems, and full App Store and Google Play publishing management.

When do you need a custom mobile app?
What's included?
iOS and Android
A single app reaching both platforms with Flutter or React Native, or native development in Swift and Kotlin when performance or hardware justify it. We respect the Human Interface Guidelines and Material Design so it feels native on each one.
Offline use and sync
Local storage and sync with your backend so the app keeps working without a connection and reconciles data once the signal returns — key for field sales, logistics or areas with poor coverage.
Push notifications and deep linking
Segmented push notifications, deep links that open the right screen from a link or campaign, and integrated usage analytics to measure real adoption and retention.
Payments and in-app purchases
Subscriptions and in-app purchases complying with Apple and Google rules, or external gateways (card, transfer, in-store payment) depending on your business model.
Device hardware access
Camera and QR/barcode scanning, geolocation (GPS) and maps, sensors and Bluetooth/BLE for peripherals or connected devices. We integrate what your use case needs, without promising features the device can't deliver.
Backend & systems integration
We connect the app to your existing APIs and systems (ERP, CRM, custom backend) with secure authentication and token handling. If you have no backend, we build the API the app needs — we are a full software factory, not just a mobile front-end studio.
CI/CD & build distribution
An automated build, signing and distribution pipeline via TestFlight (iOS) and Firebase App Distribution (Android), so you get a working build every 2 weeks without waiting until the end. Versioning, controlled releases and crash reporting integrated from day 1.
Store publishing and management
We prepare the assets, configure the listings, submit for review and manage the App Store and Google Play process — including responding to rejections — until the app is published and ready for updates.
How we work
Strategy
We define with you whether native or cross-platform fits based on performance, budget, target platforms and time-to-market. Deliverable: locked scope, fixed budget and timeline — no surprises mid-way.
Design
Figma prototypes that respect the Human Interface Guidelines (iOS) and Material Design (Android), including the offline flows, hardware permissions and payment screens. Deliverable: a navigable prototype validated with you before writing code.
Development
2-week sprints with CI/CD, code reviews and automated testing from day 1, supported by our internal ARIA platform. Deliverable: a working build in your hands every fortnight via TestFlight (iOS) and Firebase App Distribution (Android).
QA on real devices
We test on a range of physical devices (iOS and Android), validating performance, offline, permissions and each integration's failure modes. Deliverable: a stabilized release candidate with the critical defects closed.
Publishing
We submit to the App Store and Google Play under your own developer accounts, manage the review — including responding to rejections — and coordinate the launch. Deliverable: the app published in both stores and ready for updates.
Support & handover
Post-launch support with an SLA, crash monitoring and knowledge transfer. Deliverable: the code and access to both developer accounts 100% in your name from the start, plus 90 days of support.
Tech stack
The tools and platforms we build it with — chosen for your problem, not for hype.
Frequently asked questions
Native or cross-platform — which is right for me?
Cross-platform (Flutter or React Native) covers most cases with a single codebase, lower cost and faster delivery. We recommend native (Swift / Kotlin) when you need maximum graphics performance, very deep hardware access or platform-specific features. We decide it with you in the Strategy phase, by your case, not by trend.
How long does store publishing take?
Apple's review takes 1 to 3 days on average and Google Play is usually a matter of hours, though it varies by app. We manage the entire submission, listing configuration and any rejection responses until it's published.
Do I own the code and the store accounts?
Yes, 100%. All source code is in your name from the first commit, and we publish the app under your own Apple Developer and Google Play Console accounts. No vendor lock-in: if you switch providers tomorrow, you have the repo, the access and the app in your hands.
Can the app work without an internet connection?
Yes. We implement local storage and sync with your backend so the app operates without signal and reconciles data on reconnect. We design it from the start because adding offline support later is far more expensive.
How long does it take to build an app?
It depends on scope. An app with a focused set of screens and one or two integrations usually takes 8 to 14 weeks to publish; a product with offline, payments, hardware and a custom backend takes longer. We deliver a working build every 2 weeks, so you see real progress from the start, and the timeline is locked in the Strategy phase.
How much does it cost to build an app?
It's quoted by scope: number of screens, integrations, target platforms (iOS, Android or both) and business logic complexity. We work with a fixed budget defined in the Strategy phase — no hourly billing, no ambiguous scope. The assessment gives you an estimated range for free in minutes.
