Overview

How we work and what you get

Mobile apps often start as an MVP: one platform, one critical flow, measurable user value. Feather Studio builds iOS and Android apps (Flutter or native when required) with clear boundaries around offline mode, notifications, payments, and backend sync.

Flutter shares business logic across platforms and speeds iteration when the UI does not need to be exclusively native. We go native when specific SDKs, strict performance, or deep OS integration demand it.

Design follows platform guidelines (Human Interface / Material) while staying on-brand. Prototypes and on-device testing reduce late discoveries around gestures or readability.

App Store and Google Play submissions require listings, privacy copy, versioning, and sometimes review loops — we guide you through requirements.

The backend may be an existing API, BaaS, or custom service; we define authentication, token refresh, and data protection at rest and in transit.

Analytics (e.g. Firebase / GA4 in-app) and crash reporting are wired so you know what to improve in the next release.

Contact us for scope: screen count, integrations, supported OS versions, and timelines — you get a clear proposal and release plan.

FAQ

Frequently asked questions

How much does mobile app development cost in Serbia?

A Flutter MVP app for iOS and Android starts from €5,000 for a simpler project. Medium-complexity apps (payment, chat, map) cost €15,000–€35,000. The exact price depends on features and backend requirements.

Do you build both iOS and Android apps?

Yes — we use Flutter, which generates native iOS and Android apps from a single codebase. This reduces cost by 30–40% compared to developing two separate native apps.

How long does mobile app development take?

A Flutter MVP app typically takes 2–4 months. More complex apps with advanced features and a custom backend take 4–8 months. The timeline is precisely defined in the discovery phase.

Do you help with publishing to the App Store and Google Play?

Yes — alongside development we help with submitting to the App Store (Apple) and Google Play (Google), including preparing screenshots, descriptions and all metadata required for approval.
