Mobile App Development
The mobile app your business needs, built to measure
We develop native and hybrid apps for iOS and Android tailored to your company's real processes — from field operations to the end-customer experience.
Our approach
A mobile app for your business is not a stripped-down version of your website. It is a working tool that must be fast, intuitive and functional even without internet connectivity. We design it so your team uses it every single day from day one.
Talk to an expertWe start from how your employees and customers actually work, not from generic templates. The result is apps that get adopted quickly, are used daily and reduce operational friction.
We connect the mobile app with your ERP, CRM, database or any backend service. Mobility joins your technology ecosystem without duplicating data or processes.
We design the sync logic so the app works correctly without connectivity and syncs automatically when the network is available. Essential for field teams, warehouse staff and logistics crews.
Types of apps we develop
Tools for technicians, installers and field workers: work orders, inspections, digital signatures, photo capture and back-office sync.
Apps for sales reps to access the product catalogue, place orders, review customer history and manage visits from anywhere, connected to your CRM or ERP.
End-user apps for purchases, order tracking, loyalty programmes, support and direct communication with your company, with a premium experience on iOS and Android.
Route and delivery management, proof-of-delivery, barcode scanning and shipment traceability integrated with transport and warehouse platforms.
Executive dashboards and real-time KPIs for managers and directors who need business visibility from any device at any time.
Mobile platforms for team training, internal announcements, shift management and employee self-service portals accessible from any phone.
Our methodology
We analyse the processes the app must solve, the user profiles, the systems to integrate and the technical constraints. The output is a product document that defines scope, priority features and high-level architecture.
We design user flows, information architecture and high-fidelity interactive prototypes. We validate the experience with real users before writing a single line of code, reducing the risk of costly rework.
We choose the most suitable technology for each project: native development (Swift/Kotlin) when performance or hardware access are critical, or hybrid frameworks (Flutter, React Native) to maximise efficiency and simultaneous iOS/Android coverage.
We run comprehensive test cycles on real devices, coordinate the beta with key users and manage the entire submission process on the App Store and Google Play, including review requirements and privacy policies.
Publishing the app is just the beginning. We monitor performance, resolve incidents, adapt the app to new iOS and Android versions and add features as your business grows and evolves.
Technical capabilities
Every app we build incorporates the technical capabilities your business needs — from offline synchronisation to integration with specialised hardware.
The app works without an internet connection and syncs data automatically when the network is available, ensuring uninterrupted operations.
Targeted alerts, reminders and communications that reach the device at the right moment to improve response times and engagement.
GPS integration for route tracking, visit optimisation, geofencing and visualisation of geolocated data on interactive maps.
Native scanning for warehouse management, access control, product traceability and any process that requires fast object identification.
On-screen signature collection, photo capture and document attachments linked to work orders, contracts or reports directly from the app.
Bidirectional connection with your ERP, CRM, database or any third-party API to keep data in sync between the app and your business systems.
Login with biometrics (Face ID, fingerprint), corporate SSO and multi-factor authentication to ensure secure access to the app.
Dashboards and KPIs embedded directly in the app so users can check relevant metrics without leaving the tool.

Complete guide
Most companies that ask us for a mobile app do not want "to be in the app stores": they want their field teams to stop using paper, their sales reps to sell from a tablet or their customers to serve themselves. This guide explains which types of app exist, when native or hybrid development makes sense, how the app connects to the ERP and what to demand in code ownership and maintenance before commissioning custom mobile app development.
Custom mobile app development means building an iOS and Android application that follows your company's real processes, instead of adapting the company to a generic app. It is not a cut-down version of the website or a shop window: it is a working tool used in the warehouse, in the van, on site or in front of the customer, often without coverage and with one hand busy.
That is why the starting point is never the technology but the process: who uses the app, where, how many times a day and what has to happen in the central system when they press a button. A work report that reaches the ERP with photos and a signature, an order that deducts stock instantly or a clock-in with geolocation is worth more than any flashy feature. At Grupo Unifema we design apps from that process and connect them to the company's management system from day one.
It is the first technical decision and it drives cost, timescale and maintenance. Native means one specific development for iOS (Swift) and another for Android (Kotlin); hybrid means a single codebase with Flutter or React Native published on both platforms; and a progressive web app (PWA) is a website that installs on the phone and partly works offline. None is better in the abstract: it depends on what the app has to do and who will use it.
| Criterion | Native (Swift / Kotlin) | Hybrid (Flutter / React Native) or PWA |
|---|---|---|
| Performance and hardware | Maximum: camera, Bluetooth, NFC, sensors and demanding graphics with no limitations. | Sufficient for most management apps; access to specific hardware depends on plug-ins. |
| Platforms | Two developments and two maintenance streams, one per operating system. | A single codebase for iOS and Android; a PWA does not even go through the stores. |
| Time to first version | Longer, because each platform is built and tested separately. | Shorter: what is developed once works on both platforms. |
| Offline mode | Full local database and synchronisation. | Just as complete in hybrid; limited in a PWA. |
| Maintenance cost | Higher: every iOS and Android release means reviewing two projects. | Lower: one codebase updated once. |
| When we recommend it | High-volume consumer apps, intensive hardware use or a highly polished brand experience. | Internal field, sales force, logistics, customer portal and employee portal apps. |
In practice, most of the business apps we build are hybrid: they solve what the company needs with a single codebase and half the maintenance. We reserve native development for cases where hardware or performance demand it, and we decide it together with you during analysis, with the process in front of us and with no attachment to any particular technology.
The type of app that solves a problem changes with the sector. These are the ones we are asked for most and what they usually include:
An app that does not talk to the company's systems creates a data island and ends up abandoned. Every app we develop connects through a secure API to what you already have, and that integration is usually the most important part of the project. These are the usual connections:
Publishing the app is part of the project. We handle the Apple and Google developer accounts, store reviews, signing and the privacy policies they require. For internal apps there is also private distribution, which bypasses the public stores and installs the app only on the company's devices.
An app lives in an environment that changes every year: new iOS and Android versions, new screen sizes, new store and security requirements. That is why maintenance is not optional, and it should be agreed before starting: who updates, how often and within what time an incident is handled. And one condition that should be non-negotiable: the source code, the developer accounts and the data belong to your company. At Grupo Unifema we hand over the complete, documented repository, and you can keep using and extending the app even if you stop working with us.
With just one of these signs there is already a process an app would solve in weeks. With two or more, the cost of not having it is probably being paid every day in working hours, errors and waiting customers.
We develop mobile apps for companies across Spain from our offices in Murcia and Madrid, with analysis and kick-off in person when the project requires it and the rest of the work remotely, with deliveries you can test on your own phone.
We are a software development consultancy with more than 20 years of experience and the makers of the Gestinity ERP, so we know both halves of a mobile app project: the app the user sees and the management system it has to connect to. That avoids the most common problem in these projects, a well-designed app that nobody then knows how to integrate.
Every project starts with an analysis meeting with the people who will use the app, which produces a scope document with screens, integrations and phases. We develop in deliveries you test on real devices, publish to the stores and keep the maintenance if you want us to. In-house technical team, fixed-price quote and the code in your name.
Tell us which app your company needsFrequently asked questions
Both. We choose the technology according to the use case: hybrid (Flutter or React Native) when you want iOS and Android from a single codebase, and native when the app needs specific hardware or maximum performance.
Apps for sales teams, field technicians with work orders, logistics and delivery, customer portals, time tracking and employee portals, and product apps for businesses selling to the public.
Yes. We design field apps to work offline and sync automatically when connectivity returns, which is essential in warehouses, industrial sites or rural areas.
That is the usual case. The app connects to your ERP, CRM or management application through a secure API so orders, work reports or clock-ins reach the central system in real time.
Yes. We manage the developer accounts, the publishing process, store reviews and subsequent updates.
A business app with integration is usually published within 10-16 weeks, depending on the features. We give you a fixed timeline and quote after the analysis meeting.
