Telz: international calls with the price up front
Since 2023 we have been the Android team behind Telz, an app for low-cost international calls. We turned an open-source SIP client into a paid product with upfront pricing and top-ups.
Flemish-Based Android Studio
A boutique Flemish-based mobile studio. Combining local technical architecture with a dedicated senior engineering team to deliver scalable MVPs, complex enterprise systems, and guaranteed long-term support (SLA).
Google Play requires apps to target a recent API level every year. Miss the deadline and new users on newer Android versions can no longer find or install your app, and you can't publish updates until you catch up. Without a maintenance partner, this is a silent killer.
Un-maintained apps accumulate crashes with every new Android release and device variant. By year two, a neglected codebase can reach critical crash rates that destroy user trust.
Fast MVPs often carry structural shortcuts. Without deliberate refactoring milestones, these shortcuts compound into rewrites — costing 3× to 5× the original build.
Rapid, scalable validation for startups and new business ideas. We build your Android MVP on a clean, documented architecture from day one. No shortcuts that haunt you later. Every sprint is designed for long-term maintainability.
Complex systems, API/ERP integrations, IoT, and high-load architecture. We deliver robust solutions tailored for enterprise requirements, ensuring seamless performance and integration with existing infrastructure.
De-risking large projects with thorough technical architecture, UI/UX framing, and specifications before coding. Ensure alignment and clarity on requirements to minimize costly pivots during development.
Guaranteed first-response times, proactive monitoring, yearly target API updates and dedicated monthly development hours.
Case studies from our track record of shipping high-performance mobile products.
