Mobile Development

Mobile Products Engineered for Retention and Long-Term Growth

Jasiri Limited builds native and cross-platform mobile applications for iOS and Android – designed around performance, usability, and the way people actually use their devices. Every release is tested against actual user behaviour, not only against specifications.

Platforms & Tech Stack

The choice between native and cross-platform development is an engineering decision.

It depends on performance requirements, device features the product needs, release frequency, and the long-term cost of maintaining the codebase. At Jasiri, we make this choice together with you, based on the product roadmap, not on a default preference.

iOS

Native development in Swift and SwiftUI. We recommend it for products that depend on platform-specific features, advanced animations, or tight integration with the Apple ecosystem.

Android

Native development in Kotlin. Built to perform consistently across the wide range of Android devices, screen sizes, and OS versions.

Cross-Platform

Development with React Native and Flutter. One shared codebase for iOS and Android shortens time to market and reduces maintenance effort, while platform-specific modules are added where native performance matters.

From Plan to Launch

Development Process

Mobile development at Jasiri follows a structured sequence, from the first requirements to the version users download from the store.

01.

Product and Technical Discovery

User scenarios, target devices, and business goals are translated into technical requirements. At this stage, we define the platform approach, the architecture, and the metrics the app will be measured by: retention, session length, crash rate, load time.

02.

UX-First Design

Interfaces are designed for how people use mobile apps: short sessions, one-handed interaction, unstable connections. Screens adapt to different device sizes and orientations, and key flows are validated with prototypes before development starts.

03.

Iterative Development

We build the app in short iterations, with a working build available for your review at the end of each cycle. Architecture decisions account for future features, so the app can grow without a rewrite.

04.

Testing on Devices

Functional, performance, and usability testing runs on physical devices and emulators across OS versions. Automated tests cover core flows and run with every build.

05.

Store Deployment and Compliance

Jasiri Limited prepares and manages releases on the App Store and Google Play: builds, metadata, privacy disclosures, and review requirements. Store guidelines are considered from the design stage, which reduces the risk of rejected releases.

06.

Post-Launch Monitoring and Improvement

After release, the Jasiri team tracks crash reports, performance metrics, and user behaviour data. We use these findings to plan the next iterations – fixes, optimizations, and new features.

Built for Real-World Use

Key Capabilities

Performance Optimization

Fast launch times, smooth scrolling, and responsive interfaces. We profile and optimize memory usage and battery consumption, so the app stays efficient during long sessions and on older devices.

Offline Mode

Core functionality remains available without a stable connection. Data is stored on the device and synchronized when the connection returns, with conflict handling built in.

Adaptive Interfaces

Layouts adjust to different screen sizes, resolutions, and orientations – from compact phones to tablets.

Push Notifications

Notification systems for iOS and Android with segmentation, scheduling, and delivery tracking – configured to support retention without overloading users.

Deep Linking

Links that open specific screens inside the app from emails, ads, websites, and other apps. Deep linking connects marketing campaigns and user journeys directly to the relevant content.

In-App Analytics

We integrate analytics tools that track user flows, feature usage, and drop-off points, so product decisions are based on how users behave in the app, not on assumptions.

Security by Design

Data encryption in storage and in transit, secure authentication flows, token handling, and protection of sensitive data on the device. We build security into the architecture from the first sprint.

Built beyond the launch

Why Jasiri

Engineered for retention

A mobile app is measured by whether users come back. At Jasiri, we design, test, and improve apps with retention as the core metric – not download numbers.

Accountability after launch

The first release is the start of the work, not the end. We stay involved: OS updates, performance monitoring, security updates, and new features based on usage data.

Full cycle in one team

Mobile engineering, UX/UI, QA, analytics, and growth work within one structure. The app is built with its testing, measurement, and growth already planned.

Experience with trust-sensitive products

Jasiri Limited builds for marketplaces and consumer products where users share personal data and make payments inside the app. Secure authentication, data protection, and in-app payment flows are handled as core engineering work.

AI in the product and in the process

We plan AI features in the architecture from the start and use AI in our own delivery: quality control, analytics, and process automation.
