Services / Our Services

Mobile App Development (iOS & Android)

At Candemsoft, we engineer fluid, high-performance mobile applications for iOS and Android ecosystems. Based in Istanbul, our engineering team utilizes Flutter and native technologies to deliver end-to-end architecture, intuitive UI, backend integration, and store submission. We publish client applications with the same rigor we apply to our own App Store and Google Play products.

Target & Use Cases

Who Is This For?

Our mobile development services are designed for businesses aiming to engage users directly through frictionless smartphone experiences.

01

Mobile-First Startups

Innovative ventures looking to validate their market rapidly on the App Store and Google Play with an engaging initial release.

02

Customer Experience Expansion

Businesses expanding web services onto mobile channels to boost customer retention and engagement through push notifications.

03

Field & Operational Teams

Enterprise teams requiring offline capabilities, GPS tracking, and hardware integration (camera, Bluetooth, QR scanners).

04

Subscription & Content Services

Publishers and educational platforms requiring in-app purchases (IAP), recurring subscriptions, and streaming audio or video.

Work Process

Our Mobile Development Process

From initial concept to store approval, we manage every phase with proven engineering rigor and complete transparency.

  1. 01

    Discovery & Scope Definition

    We clarify user journeys, platform requirements (iOS / Android), and technical architecture to establish clear project boundaries.

  2. 02

    Architecture & Interactive Prototypes

    We select state management patterns, define API contracts, and transform designs into clickable prototypes for testing.

  3. 03

    Agile Mobile Sprints

    Working in two-week sprints, we deliver testable builds via TestFlight and Google Play Internal Testing at every review.

  4. 04

    Testing & Quality Assurance

    We conduct on-device testing across varied screen sizes, OS versions, edge network conditions, and battery constraints.

  5. 05

    Store Launch & Ongoing Support

    We manage store submissions compliant with Apple and Google guidelines, followed by ongoing updates and crash monitoring.

Technologies we use

Technologies We Use

We employ modern cross-platform frameworks for unified development alongside native platform toolsets.

Our Architecture Standards & Technical Principles

Cross-Platform Efficiency & Native Performance

Selecting the optimal technical stack is critical for budget efficiency and user satisfaction. Flutter compiles directly to native machine code via modern rendering engines, delivering consistent 60 and 120 FPS interactions indistinguishable from native builds. Maintaining a single codebase allows rapid feature parity across both iOS and Android releases.

When low-level hardware access is required, we bridge Flutter with native Swift and Kotlin modules using platform method channels. This hybrid architecture pairs the velocity of cross-platform development with the raw capabilities of device-specific APIs.

Battery Consumption, Memory Management & Offline Architecture

A superior mobile application balances visual polish with respectful resource utilization. We schedule location queries, background tasks, and network requests intelligently to prevent unnecessary battery drain and device overheating. Continuous profiling identifies memory leaks and optimizes image caching.

To handle intermittent connectivity in transit or remote areas, we implement robust local persistence using SQLite or Hive. Once connectivity returns, background synchronization queues automatically reconcile conflicting records and upload changes without interrupting the user.

Store Release Experience Driven by Live Consumer Products

Candemsoft engineers understand store submission guidelines from firsthand operational experience rather than theory. Launching our speed-reading app Orpigo on the App Store and Google Play, handling background GPS reviews for Seyyah, and architecting push widgets for Kişisel QR have refined our publishing workflows.

We navigate Apple's rigorous review standards, Google's closed testing mandates, and in-app purchase validation from our own commercial deployments. Applying these hard-won insights to client engagements eliminates rejection surprises and accelerates time-to-market.

FAQ

Frequently Asked Questions

Should we choose Flutter or Native (Swift/Kotlin)?
For most projects, Flutter delivers near-native performance, rapid cross-platform deployment, and reduced maintenance costs from a single codebase. Native Swift or Kotlin is recommended when apps require specialized OS-level integrations.
How do you handle App Store and Google Play approvals?
We design applications according to Apple and Google store guidelines from day one. By preparing compliant privacy policies, permission rationale, and review credentials, we minimize rejection risks.
Can the mobile application work offline?
Yes. By implementing local persistence (SQLite, Hive) and background synchronization queues, we enable users to view content and queue actions even without active network access.
How are in-app purchases and subscriptions implemented?
We integrate StoreKit and Google Play Billing using RevenueCat or native store APIs. Server-side receipt validation and webhook handlers securely manage subscription renewals and tier entitlements.
Is ongoing maintenance required after launching on app stores?
Yes. Apple and Google release major OS updates annually. We provide recurring maintenance to ensure ongoing compatibility, patch vulnerabilities, and update third-party SDKs smoothly.
