Mobile app development company in Mexico: iOS and Android

We design, build, ship and run iOS and Android apps from Puebla, Mexico. We have 17 apps of our own in the stores, with more than 100,000 Google Play installs, and we apply the same process to client apps: from design to the store, and beyond.

02 — What’s included

What building your app includes

01

iOS and Android apps

Flutter for both platforms from a single codebase, and native Swift or Kotlin when the app calls for it: widgets, extensions or features tied closely to the OS.

Built by us: Soccer24
02

Product design

Screens and a prototype before code, so you can test the flow with real users and decide with something in hand.

03

Backend and sync

Firebase or Cloud Run, real-time notifications and an offline mode that syncs when the signal comes back.

Built by us: Inventra
04

Payments and subscriptions

In-app purchases and subscriptions on the App Store and Google Play, and Stripe payments on the web.

05

Store release and listings

Apple review, staged rollouts on Google Play and listings optimized per country and language so the app gets found.

06

Maintenance

Yearly iOS, Android and Flutter updates, review replies and crash monitoring in production.

03 — Approach

Decisions we make with you

01

Flutter or native?

Flutter when you want iOS and Android with one team and one codebase; native for widgets or OS features. Soccer24 uses both: the app in Flutter, widgets in Swift and Kotlin.

02

Phones, foldables and tablets

The app rearranges itself for each screen. PeakPlay goes from two to four columns when a Pixel 9 Pro Fold opens, without reloading.

03

The store listing is product too

A good app with a weak listing doesn't get downloaded. We publish listings per country and language and reply to reviews from day one.

06 — FAQ

What people usually ask

How much does it cost to build an app?

It depends on scope, platforms, integrations with your systems and whether AI is involved. The first call and the proposal are free: you get scope, schedule and price in writing before we start.

How long does an app take?

It depends on scope. The proposal includes a week-by-week schedule, with frequent builds you install on your own phone through TestFlight and Google Play internal testing.

Do you publish the app on the App Store and Google Play?

Yes, including Apple's review. The app goes out under your company's developer account, so it's yours from day one.

Can you take over an existing app?

Yes. We audit the code, update it to current iOS, Android and Flutter versions, and continue with monthly maintenance.

Do I own the code?

Yes. You receive the code, repositories, documentation and access, with full assignment of IP.

What does success look like for your product?

The first call and the proposal are free. The person who will lead your project replies in person.
