Appsidy
iOS & Android

We design and build mobile apps.

Appsidy is a mobile application studio. We take products from concept to the App Store and Google Play — native iOS and Android, built and shipped by a small team that owns the whole process.

Start a project What we do

Services

End-to-end mobile development, from the first wireframe to release and ongoing maintenance.

iOS development

Native applications in Swift and SwiftUI, built for current iOS versions and submitted through App Store Connect.

Android development

Native applications in Kotlin and Jetpack Compose, packaged and released through the Google Play Console.

Cross-platform

One codebase for both stores with React Native, when a shared build is the right trade-off for the product.

Backend & APIs

The services behind the app — authentication, data sync, payments, push notifications and analytics.

Product & UX design

Interface design, prototypes and store assets prepared to the guidelines each platform reviews against.

Release & maintenance

Store submission, review handling, versioned releases, crash monitoring and ongoing updates after launch.

How we work

A short, predictable loop. You always know what is being built and when it ships.

  1. ScopeWe map the product, agree on what version one actually needs, and set a timeline.
  2. DesignWireframes and interface design, reviewed with you before a line of app code is written.
  3. BuildDevelopment in short cycles, with builds you can install and try on your own device.
  4. ShipStore submission, review, launch — then updates and support on an agreed cadence.
