# Nexora | Mobile App Development Services > Plan and build Android and iOS apps with Nexora, connecting user journeys, backend services and notifications with testing for the agreed devices. Canonical page: https://www.nexoraesrd.com/services/mobile-app-development/ Language: English USEFUL IN THE MOMENT # Mobile App Development We build mobile apps that help people use your product wherever they are. From account access to device information and notifications, we plan a clear journey and connect it to your backend.

Image USEFUL IN THE MOMENT ## Engineering and marketing capabilities A mobile application shaped around real journeys, tested on the agreed devices and prepared for its release route. 01 ### Product and screen planning We identify the actions that belong on a phone and keep the first release focused. Screen flows cover entry points, navigation, permissions and task completion, including what happens when information is unavailable or a user needs help. - Screen map and prioritized mobile journeys. 02 ### Android and iOS delivery We plan shared application behavior alongside platform differences. Where React Native suits the requirements, a shared codebase can support both platforms, while device-specific features and user-interface behavior still receive separate review and testing. - Agreed Android and iOS application builds. 03 ### Accounts and backend connections Connect sign-in, roles and application data to the backend through defined APIs. We handle validation, session changes and authorization failures as part of the user journey, with permissions enforced by the supporting service. - Connected account flows and API integration notes. 04 ### Notifications that support action Notifications need a reason, an audience and a destination. We define the events that trigger them, the information displayed and where a tap should lead, while respecting the device permission settings and platform delivery constraints. - Notification triggers and navigation behavior. 05 ### Camera, location and NFC features Device capabilities are scoped against the actual task and supported hardware. We confirm permission needs, relevant tag or data formats and fallback behavior before implementing camera, location or NFC features in the application. - Capability assessment and agreed device integrations. 06 ### Data entry and synchronization Forms need clear validation and predictable submission behavior. We define how edits are saved, how duplicate requests are handled and what happens when local information differs from the server, with synchronization rules matched to the workflow. - Validation rules and synchronization behavior. 07 ### Interrupted-network handling Field use can involve slow or missing connectivity. We identify which actions must wait for the network and which can be supported locally, then design retry, status and recovery behavior so users understand what has and has not completed. - Documented network states and recovery scenarios. 08 ### Device testing and release preparation We test the agreed device and operating-system range, check key permissions and prepare build configuration and submission material. Store review remains the platform provider’s decision; ongoing fixes and updates are agreed as a separate support scope. - Device-test findings and release-preparation checklist. Mobile App Development ## Project deliverables and handover The list below describes typical outputs. The proposal identifies the exact items included in your project. - 01Screen flows and reviewed interface designs. - 02Application builds and connected backend features. - 03Device-permission, notification and synchronization notes. - 04Test findings, release preparation and agreed source handover. Example applications ## Business uses and applications 01 ### Field operations Record a visit, view an assigned task or check connected-device information. 02 ### Customer self-service Give users access to their records, requests and relevant updates. 03 ### Connected-product companion Pair a usable mobile experience with the information provided by a device and its cloud service. FROM IDEA TO DELIVERY ## Project planning, development and delivery - 01 ### Define the mobile job Agree the users, environment and tasks the application must support. - 02 ### Map the screens Review navigation, task flows and important loading or error states. - 03 ### Confirm dependencies Check API access, device functions, notification services and release accounts. - 04 ### Build the journeys Implement screens and integrations in increments that can be demonstrated. - 05 ### Test on devices Check agreed platforms, permissions, interrupted connectivity and recovery behavior. - 06 ### Prepare the release Package builds, complete handover and support the agreed submission steps. USEFUL IN THE MOMENT ## Technology and integration choices Tools follow the requirements. We consider your current systems, team skills, operating costs and support responsibilities before agreeing a technical approach. 01 ### Application approach Evaluate React Native and any required platform-specific work against the agreed Android and iOS features. 02 ### Backend services Connect to documented APIs for accounts, records, notifications and other approved application functions. 03 ### Device capabilities Confirm compatibility against actual hardware, operating-system support, permissions and third-party libraries. FROM IDEA TO DELIVERY ## Plan your project scope You do not need every answer before contacting us. Share what is already known; we can work through the open questions together. - Priority mobile tasks and the platforms your audience uses. - API documentation, test accounts and any existing application source. - Required device features, example NFC tags where relevant and store-account ownership. NEXORA / FAQ ## Service scope and project questions ### Do we need both Android and iOS? That depends on your audience and deployment needs. We can scope one platform first or plan both, with shared features and platform-specific work made clear. ### Can you use our existing backend? Yes, subject to the available APIs, authorization model and test access. Missing endpoints or required backend changes become explicit parts of the scope. ### Will the app work offline? Only the agreed functions can work without a network. We need to define local data, storage limits, synchronization and conflict handling rather than assume every feature can be offline. ### Can you add NFC or location features? We first verify the intended function, permissions and supported devices. NFC compatibility also depends on tag technology, data format and operating-system restrictions. ### Do you publish the app to the stores? Release support can include packaging and submission preparation using your developer accounts. Store policies, review decisions and account approvals are controlled by the platform providers. ### What happens after launch? We agree support ownership, update arrangements and issue reporting before release. New features, platform updates and third-party changes may require additional development and testing. PLAN YOUR PROJECT ## Useful reading before you begin. ### Planning Cloud, Web Dashboards & Mobile Apps A web dashboard and a mobile app are two ways to use the same product. Planning them together helps your team avoid mismatched data, repeated work and confusing user journeys.
