Our Cross Platform App Development Services

Prodgrade is a cross platform app development company focused on quality, speed and maintenance. We start with your goals, your users and your operations. We map the jobs your app must do, where it connects, and how it will grow. From there we propose a plan that balances scope, time and cost. We select frameworks such as React Native and Flutter, define native modules where needed, and set standards for performance, security and observability. Our work aims to reduce rework while keeping room for change as your product scales.

Strategy and Architecture

Cross platform works best when structure is clear. We design domain models, choose state patterns and plan storage so the app stays quick and stable. Where device features matter, we create small native bridges for camera, location, biometrics or media. We define performance budgets for cold start, scroll and interaction so screens feel responsive on real devices.

React Native & Flutter Development

We build with React Native and Flutter to reach iOS and Android with one codebase. Shared logic handles navigation, state and data. Native modules support features that need a closer link to the device. We focus on layout speed, smooth gestures and memory use so the result feels natural on both platforms. We provide cross platform mobile app development services that respect the design patterns of each platform while preserving a unified core.

Enterprise Mobility

Large organizations need reliability, clear identity and safe integrations. We set role based access, logging and incident paths early. We align with finance, audit and privacy needs. Release channels and rollbacks are documented. Your mobile estate grows in a planned way with predictable results.

UI and UX Design

Design begins with real tasks for owners, staff and customers. We write flows, sketch wireframes and produce a clickable prototype that uses your terms, not ours. Icons, spacing and gestures follow platform norms so the app feels at home on Apple and Android. Accessibility is planned early. We test with a small group, watch where they slow down and adjust before build work begins. The goal is clear screens, simple actions and fewer errors.

APIs and Integrations

Your product connects to CRM, ERP, identity, payments, analytics and content. We design stable APIs, set rate limits and retries, and add observability so issues are found early. We plan for versioning and deprecation to prevent outages during change. Secrets live in a managed vault. Sandboxes hold sample data so tests are realistic without exposing real records. This approach keeps portals, stores and subscription flows stable as you grow.

Offline Sync

Field staff and traveling users need tools that work with limited networks. We design local data stores with compact payloads, safe conflict rules and queues for retries. A driver can complete steps, a nurse can record notes, a sales rep can log activity. When a connection returns, the app syncs and confirms results. People do not lose work and records stay consistent.

Security and Compliance

Security is part of design. Data is encrypted in transit and at rest. We define access rules and audit logs. Permissions are clear. We align with your compliance scope such as GDPR or HIPAA and record evidence for reviews. Stores and tracking disclosures are handled with care.

Launch and Support

We prepare App Store and Play Console assets, notes and review answers. We plan a steady release cadence and keep change notes clear. After launch we watch real usage, raise adoption where needed and reduce support work by fixing what causes confusion. Your product stays current with new devices, new OS versions and new features that matter to your market.

Our Cross Platform App Development Process

Our mobile app development lifecycle is centered around collaboration, quality and outcomes. As a top cross platform app development company, we follow a structured process that ensures your product is built efficiently, meets business goals and delivers long-term value.

Each phase of our process is transparent, iterative and tailored to your unique needs.

cross platform app development
Discovery & Objectives

We begin with outcomes, user roles and the specific tasks your app must support. Short workshops and interviews surface what works today, where time is lost and which results matter most. You receive a brief that lists scope, success measures, constraints, integrations and a practical first timeline that product and engineering can trust.

We review current APIs, identity, payments, analytics, logging and native modules. We profile device coverage, network quality and security policy. This step removes surprises later by setting expectations for performance, privacy and support across iOS and Android.

We align the technology to your team and roadmap. React Native or Flutter for shared UI and logic. Kotlin Multiplatform when native screens are preferred and core logic should be shared. dot NET MAUI where a Microsoft centered estate fits best. We document contracts, offline rules, release targets and acceptance tests so progress is measurable.

Flows, wireframes and a clickable prototype show how jobs get done on a phone or tablet. Copy uses your domain language. Visuals follow platform norms and your brand so the app feels natural in both stores. Accessibility is planned from the start to support assistive technologies.

Work moves in small, inspectable steps. Client and server advance together so contracts stay in sync. Code is reviewed and scanned automatically. Decision logs explain tradeoffs in plain language. You test builds on real devices at regular checkpoints and give feedback while change is easy.

Testing is not a single step. Unit tests, integration tests and usability checks run throughout the sprint. Before release we add security scans, performance checks and data migration tests when needed. 

We set up staging and production with clear access controls, secrets management and backups that are tested. Releases use pipelines, and rollbacks are documented so a bad build never becomes a long night. Your custom software development service should feel bored at this stage. That is a good thing.

After launch, we watch stability, speed and business outcomes. We queue changes that raise ratings, increase task completion or reduce support requests. New device sizes and OS changes are tested early. Your staff receives runbooks, access and diagrams so ownership is clear.

Frequently Asked Questions

How do we choose the right cross platform tech for your app?

We handle it for you. We map your goals and features, compare React Native and Flutter, run a small proof on real devices, then share a one page recommendation with cost and timeline. You approve the plan and you own the code and store accounts.

We design local stores with clear ownership rules. Changes are queued with timestamps and device IDs. On reconnect, merges follow predictable priority rules and never silently discard edits. Users see plain language explanations and can retry without losing work.

Data is encrypted in transit and at rest. Tokens live in secure storage. We minimize what the app retains and set retention windows. Access follows least privilege. For regulated industries, we keep evidence for reviews and ensure regional data rules are respected.

We profile start time, frame time and memory on a representative device set. We trim bundles, lazy load non critical paths, paginate heavy lists, optimize images and reduce bridge traffic. Performance budgets are part of the definition of done.

A focused slice solves one real job such as browse to checkout, appointment to result or job to invoice. It includes analytics, crash reporting and support links. Most programs begin with a three to four milestone plan that proves the core loop before adding advanced features.

We prepare assets, privacy labels and permission justifications early. Internal builds validate flows before external review. For sensitive categories like health and payments we include extra time for questions. We keep checklists for App Store and Play Console so submissions are predictable.

Yes. Contracts are versioned and include examples. We honor rate limits, retries and idempotency rules. For identity we support single sign on and account linking. For CRM and ERP we design sync that tolerates intermittent networks and provides clear audit paths.

Dashboards show adoption, retention, crash free sessions and completion of key tasks. We track the effect of notifications and experiments on the outcomes you care about. 

You do. Repositories, build accounts, signing keys and store listings live in your organization. We hand over diagrams, runbooks and access so your team can operate with confidence.

Yes. We build tenant aware apps with plan rules and entitlements, and we add assistants, vision and retrieval where they add measurable value. Actions that touch money or private data always require user confirmation, and dashboards track accuracy and cost.
