Mobile App Development

Mobile App Development for Startups and Businesses

We build mobile apps for iOS and Android with React Native and Expo — authentication, payments, push notifications, and realtime features included from the start, not added on afterward.

What mobile app development

Mobile app development at Algorimsoft means engineering a real, store-ready application: the client app, the backend and APIs it talks to, and the launch process (app store submission, analytics, crash reporting) needed to actually ship it to users, not just a design file.

Business problems this solves

  • A product idea needs a mobile app but the team has no in-house mobile engineering
  • An existing app is slow, crashes frequently, or is difficult to update
  • Push notifications, payments, or realtime features need to be added to an existing app
  • The team needs both iOS and Android from one codebase without duplicating engineering effort
  • App store submission and release management is unfamiliar territory

Capabilities

React Native & Expo development

Cross-platform apps from a single codebase, avoiding duplicate native engineering where it isn't needed.

iOS & Android delivery

Native module integration where required, plus app store and Play Store submission.

APIs & backend integration

The backend services and APIs a mobile app depends on, built or integrated as part of the same engagement.

Authentication

Sign-in flows including social auth and secure session handling.

Payments

In-app purchases or payment processing integrated to your product's billing model.

Push notifications

Transactional and engagement notifications wired into your backend events.

Realtime functionality

Live updates, chat, or tracking features built on websockets or realtime databases.

Analytics & app deployment

Usage analytics, crash reporting, and a repeatable release process.

How we build it

  1. 01

    Product scope

    Define the core mobile flows that matter most for launch.

  2. 02

    Design handoff / UX review

    Confirm screens and flows are technically buildable and performant on real devices.

  3. 03

    Build

    Iterative development with builds testable on real devices throughout, not just at the end.

  4. 04

    Backend & integrations

    Connect the app to APIs, auth, payments, and notification services.

  5. 05

    Release

    App store and Play Store submission, plus analytics and crash monitoring at launch.

Technologies

  • React Native & Expo
  • TypeScript
  • Native modules (Swift / Kotlin) where required
  • Push notifications (APNs / FCM)
  • Realtime (WebSockets, Firebase, Supabase Realtime)
  • Payments (Stripe, App Store/Play Store in-app purchase)

Use cases

  • Launching a companion mobile app for an existing web product
  • Building a consumer app with authentication, payments, and push notifications
  • Adding realtime tracking or chat to an existing mobile app
  • Taking over and stabilizing an existing app with performance or crash issues

Industries served

Why Algorimsoft

  • React Native and Expo are used deliberately for the engineering-speed and maintenance benefits of a shared codebase, with native modules where the app genuinely needs them
  • The backend and APIs the app depends on are built by the same team, avoiding integration gaps between a mobile agency and a separate backend vendor
  • App store submission and release management are handled as part of delivery, not left to the client to figure out alone

Engagement options

New app build

A full mobile app built and shipped to both app stores.

Feature engagement

Adding a specific capability (payments, push, realtime) to an existing app.

Stabilization engagement

Taking over an underperforming app to fix crashes, performance, or release process issues.
