01Overview
App, backend and release scope
We scope the mobile product around its users, devices and connected systems. Discovery produces a written platform recommendation and a phased release plan covering the app, backend, design and store submission work.
- The platform call comes firstThe required device features and maintenance needs guide the native or cross-platform recommendation. iOS and Android covers the options in detail.
- Device and network testingWe agree the devices, OS versions and network conditions the app needs to support, then test against that scope.
- The backend comes with itThe mobile scope includes its backend and connectors, with integration work and design coordinated with the app.
- Continued development after releaseApp updates, dependency changes and backend improvements continue under an agreed maintenance scope.

Mobile products for customers and field operations
Our mobile work includes customer and dealer workflows, API-connected operational tools and paperless vehicle inspection.
- Mover Technologies: apps for customers and dealersFounder Boruch Akbosh described the apps on Clutch: "We have apps for iOS and Android for both customers and dealers." Customers capture inventory for quotes; dealers see assigned job orders and change their statuses. The platform also gathers dealer and freight-carrier API data for live quotes.2audiences on the Mover Technologies freight platform
- Mobile apps and portals for a software consulting firmWe developed mobile apps and web portals for a US software consulting firm. Its CEO reported the scope on Clutch: "It’s probably been a total of four mobile apps and three or four portals." His quality assessment: "We never had a quality issue with them."six out of sevenengagements on time and on budget for that firm, each one a minimum of six months of effort
- A field app carrying operational loadWe built a cross-platform iOS and Android paperless inspection app in Xamarin.

10Client voices
Client reviews of our mobile and platform work
The project led to the release of our production apps and a prototype showcasing new features. They were reliable, responsive, and consistently addressed our needs very well. We were impressed by their strong technical and interpersonal skills and how smoothly they adapted to our team, processes, and product.
I’m consistently humbled by Artelogic’s performance. Projects of this caliber are hard to outsource. Teams come and go, and this type of work almost never gets done. They’ve kept their priorities straight as they’ve grown and always deliver.
They were perfect. Nothing got lost in translation and we managed the time difference well. Artelogic has been professional, personable, and flexible, especially when it comes to our budget after the pandemic.
Our platform has been refactored to Laravel ensuring the code base is more stable, easier to maintain and easier to add new features. Their professionalism and quality of work have stood out in the partnership. We have had the code audited by a 3rd party who was extremely complimentary of the work.
Our website’s overall functionality has been improved both in frontend possibilities and user experience as well as backend aspects of website management and financial monitoring. These are not easily qualitfiable but there has been a net gain in available staff hours for alternative projects as a result of improved website abilities reducing workload.

12Questions
Mobile app development questions
Platform choice, integrations, cost, store timing and takeover scope are decisions to settle before commissioning an app.
We recommend the platform from your users' devices, required device features and the application's maintenance needs.
Discovery examines:
- The iOS and Android devices the intended users carry.
- Camera, GPS, storage, notifications and network requirements.
- The app and backend work your team will maintain after release.
We record the native or cross-platform recommendation and its reasoning. iOS and Android covers the options in more detail.
The choice depends on required device features, distribution and maintenance; we build native and cross-platform apps.
- Cross-platform: React Native or Flutter shares application code across iOS and Android, with platform-specific requirements included in scope.
- Native: Swift or Kotlin provides a platform-specific implementation for iOS or Android.
- Hybrid: HTML5 and JavaScript run inside a native shell; suitability depends on the application's requirements.
- Progressive web app: browser-based software accessed by URL that can be installed, with device and offline capabilities depending on the platform.
Discovery compares the options against the workflow you need to support.
The timeline depends on the platform, application scope, backend and integration work, and the reviews needed from your team.
Discovery produces a phased release plan with agreed delivery dates. Design work, existing-system access and product decisions affect that plan. App Store review also affects release timing, so submission and review work are included in the schedule.
We quote mobile app development from the agreed application scope and delivery model.
The estimate covers:
- Features and application complexity.
- Native or cross-platform implementation.
- Backend and third-party integrations.
- UI/UX and QA requirements.
Discovery produces the detailed estimate before you commit to the build.
- Time and materials: billed hourly, quoted per project.
- Fixed price: outcome based, quoted per project.
- Team extension: billed monthly per team member.
Yes. We scope the mobile app's backend integrations around the APIs and systems you already run.
Our trailer-tracking portal work combined mobile and web components, third-party APIs for vehicle validation and a client's API for registering events.
Broader system-integration experience includes rental operations connected to MINDBODY and vehicle-maintenance service intelligence.
Yes. We assess an existing app for continued development or scope a mobile client for a product you already run.
We contributed layout, theming and video-streaming improvements to iOS and Android apps built on an existing web client. Our work for a national governing body in Ireland included a React Native membership and race-planning app.
When the main work is the underlying system, legacy modernization defines that scope.
We agree the app's security, QA and compliance requirements during scoping, including device data and credentials and communication with the backend.
unicrew is ISO 27001:2022 and ISO 9001:2015 certified, renewed through a multi-stage audit with Quay Audit UK. We have ISTQB-certified QA engineers; the build scope defines the controls and acceptance requirements for your application.
On build engagements, access is least-privilege and agreed with your technical contact, read-only wherever the work allows, with no write access to production systems during discovery. Rescue and maintenance access are scoped separately.
Compare relevant installed-app work, backend integration, store-release responsibilities and the proposed maintenance arrangement.
With unicrew, you receive a written platform recommendation and agree app, backend and release responsibilities within the mobile scope. Ownership and transfer terms are settled before work starts. Continuing support has its own agreed scope.
Our client reviews describe the mobile and integration work delivered by our senior in-house engineers.
unicrew fits a mobile product where the app, backend and store release need coordinated engineering for customer or operational workflows.
Discovery defines the users, device requirements and first release. For an aging underlying system, modernizing the system behind the app addresses that work within its own scope.
