Adastra has delivered a modern application portal that has simplified the collection and management of mandatory data from electricity producers and prepared us for a significant expansion in the number of external entities involved. As a result, we already have hundreds of parameters from dozens of power plants under control — and next year, we plan to onboard thousands more.

Application Development FAQ

How to choose between native, multiplatform or web app development?

It depends on your users, required features, budget and timeline. Native apps give the best performance and full access to device features. Multiplatform apps reach iOS and Android from one codebase at lower cost. Web apps are the fastest to launch and the easiest to maintain. Adastra helps you weigh these trade-offs in initial workshops.

Simple apps typically take 1 to 3 months, moderately complex apps 3 to 6 months, and complex apps with extensive integrations or AI from 6 months to a year or more. Adastra confirms the timeline after business and system analysis, and agile delivery lets you release a first working version early.

We follow six steps: initial workshops, business and system analysis, UX/UI design, development, testing, and finalization with ongoing support. Each step has clear outputs that you approve, so scope and budget stay transparent throughout the project. DevOps practices and automated testing keep releases stable as your application grows and changes.

Yes. Most business apps need data from ERP, CRM, loyalty, payment or core systems. Adastra designs secure integrations through APIs and middleware, so the app works with your current landscape instead of creating another silo. For Tesco, we built integrated e-commerce and loyalty apps that power personalized, data-driven omnichannel marketing.

Adastra can. Our maintenance and support covers monitoring, bug fixes, security updates, operating system compatibility and new features. If you prefer to take the application in-house, we document the code and architecture and hand over the knowledge your team needs, so you are never locked in to a single supplier.

Adastra builds e-commerce apps, loyalty and personalization apps, internal operational apps and fully custom solutions. Examples include a unified mobile platform for digital lottery services and the Sazkabet betting app for Allwyn, paperless insurance applications for MetLife, and a single mobile application for benefit management and user retention for Pluxee.

Security is part of every phase. Adastra applies secure coding practices, security testing and access control, and encrypts sensitive data in transit and at rest. We align the application with the regulations that apply in your industry, such as financial services or insurance, and keep it patched and monitored through ongoing support.
