Android App Development
Applications built for Android phones and tablets, with a responsive interface, backend integration and attention to device compatibility.
Zerothcode helps businesses turn ideas and workflows into mobile applications designed around real users, not just a feature list.
Whether that means an Android app, an iOS app, a cross-platform build, or an internal business app connected to your existing systems, we plan for usability, performance, integrations and what happens after launch.
Zerothcode supports different stages and types of mobile app development depending on what your business actually needs.
Applications built for Android phones and tablets, with a responsive interface, backend integration and attention to device compatibility.
Apps built for iPhone users, with a platform-aware interface, backend integration and App Store release readiness.
A shared development approach across Android and iOS where that fits your budget and timeline, using Flutter or React Native.
User flows, wireframes, prototypes and screen layouts designed around how people actually use your app. See UI/UX Design.
Early-stage help with idea validation, feature scope, platform choice and technical architecture before development starts.
Testing across functionality, devices, operating systems, integrations and key user journeys before release.
Bug fixes, compatibility updates, API updates and performance improvements after your app is live. See Maintenance & Support.
Internal apps that support operations, workflows, reporting and field teams, connected to your existing business data.
Apps connected to your backend systems, CRM, payment services or external APIs rather than working in isolation.
The right technology is chosen based on your app's requirements, performance needs, target users and maintenance expectations - not a default stack.
Built using Kotlin and Java, optimised for device compatibility and Play Store readiness.
Built using Swift, designed to feel native to iPhone users and ready for App Store submission.
Cross-platform applications built with Flutter for a consistent interface across iOS and Android.
Cross-platform apps built with React Native, sharing logic across platforms while staying close to native performance.
We focus on understanding your business and users before writing a line of code, and we stay involved after launch rather than disappearing once the app ships.
An iterative process from concept through launch and continuous improvement.
Understand the business goal, target users, core problem and expected outcomes.
Define modules, user roles, features, workflows and MVP priorities.
Choose the appropriate platform, framework, backend and APIs.
Build the mobile front end, application logic and backend integration.
Test functionality, device behaviour, key workflows, integrations and performance.
Prepare the approved app for App Store and Google Play submission.
Monitor issues, improve performance, and respond to OS changes and user feedback.
Discuss your requirements with Zerothcode and turn your concept into a clear mobile development plan.
Discuss Your App IdeaPossible capabilities depending on your app's requirements - not every feature applies to every project.
Sign-up, profiles and preferences.
Timely updates and alerts.
Login flows built with security in mind.
Suitable payment providers integrated for your app.
Location-aware features where relevant.
Photo, video or media capture where needed.
Scan-based functionality where relevant.
Live data and status changes in the app.
Connections to your backend and third-party APIs.
Reporting and data views inside the app.
Usage tracking to inform product decisions.
Sensible behaviour when connectivity drops, where appropriate.
Mobile applications can support organisations across a range of sectors - the right approach depends on how that business actually operates.
The same five-stage approach we apply across our development services.
Align around users and objectives.
Define scope and technical approach.
Create flows and interfaces.
Develop iteratively.
Test, learn and refine.
Many business apps need to connect with existing software rather than operate in isolation. We build API connections to the systems you already run, extending into Software Development, Custom Software Development or CRM Development where deeper backend work is involved.
We follow security-focused development practices, test thoroughly before release, and design with performance and future maintenance in mind - without making guarantees no team honestly can.
Sensible handling of login and permissions.
Data handled responsibly between app and backend.
Attention to load times and responsiveness.
Core features tested against real user journeys.
Checked across common device sizes.
Verified against current Android and iOS versions.
Checking existing features still work after changes.
A final review before submission and launch.
It depends on your target audience, how they use your product, your budget and your launch strategy. If your users are concentrated on one platform, starting there can be the more efficient route; if you need broad reach from day one, a cross-platform approach may suit better. We can help you weigh this up during discovery rather than assuming both platforms are always the right answer.
Native apps are built specifically for one platform (Android or iOS) using that platform's own tools, which can offer tighter platform integration. Cross-platform apps use a shared codebase and development approach across multiple platforms, which can reduce development effort where the requirements suit it. Each approach has trade-offs around performance, cost and platform-specific features - we'll recommend one based on your actual requirements.
Cost depends on scope, number of screens, features, chosen platform(s), backend requirements, integrations, UI/UX depth and testing needs. Share your requirements with us and we will provide a clear, no-obligation quote.
Timelines depend on complexity - a focused MVP and a full-featured business app need very different schedules. We'll give you a realistic estimate once we understand your requirements.
Yes - we design responsive, adaptive interfaces intended to work across different screen sizes, and we account for phone and tablet layouts during the UX and development stages.
Yes - mobile apps can be connected to your existing systems through available APIs. Where deeper backend work is involved, this can extend into our Software Development or Custom Software Development services, and integration with a CRM specifically is covered under CRM Development.
Yes - we support submission and release preparation for both stores. Final approval is controlled by Apple and Google directly, so we can't guarantee approval outcomes, but we prepare your app to meet the relevant store requirements.
Operating-system updates can affect app behaviour, third-party libraries or API compatibility. This is why ongoing compatibility testing and maintenance are worth planning for after launch, rather than treating a mobile app as a one-off build.
Yes - fixes, compatibility updates, performance improvements, dependency updates and feature enhancements are available through our Web & App Maintenance & Support service.
Depending on the project, we work with Kotlin and Java for Android, Swift for iOS, and Flutter or React Native for cross-platform development - chosen based on what your app actually needs rather than a default stack.
Mobile app development covers the planning, design, coding, API and backend integration, testing and ongoing improvement involved in building an application for phones and tablets.
Native apps are built specifically for one platform and can offer tighter integration with that platform's features. Cross-platform apps share code across platforms, which can reduce development time and cost where the requirements suit it. Neither approach is universally better - the right choice depends on your users, budget and timeline.
Common signals include frequent customer interaction, mobile field teams who need on-the-go data access, customer accounts and personalised services, a need for push notifications, or workflows that are genuinely easier to handle from a phone than a desktop.
Strong apps share a few things in common: intuitive navigation, reliable performance, accessible design, sensible security, useful (not excessive) notifications, and an interface that respects how people actually hold and use their phone.
Cost is shaped by the platform(s) chosen, number of features and screens, backend complexity, integrations required, depth of UI/UX work, testing scope, and ongoing maintenance needs.
Most business apps rely on a backend - APIs, databases and business logic that the app communicates with. Where that backend needs to be built or extended, this work falls under Software Development or, for highly bespoke requirements, Custom Software Development.
Operating-system updates, new device sizes, security patches, API changes and user feedback all mean a mobile app needs attention after launch, not just at release. Planning for maintenance from the start avoids surprises later.
Share your idea, a business challenge, an app redesign, an existing app, or an integration requirement - we'll take it from there.
