Mobile app development
Android and iOS apps built for the phones people actually own — offline-first data, small downloads, no battery drain.
Software studio
We build Android, iOS
We build Android, iOS
and web software.
Xeltriq Technologies is a small, senior team. You brief the people who write the code — and you get working software instead of a slide deck.
What we do
Software solutions, end to end
Design, build, launch and keep running. Take one service or hand over the whole thing.
Web development
Marketing sites, dashboards and progressive web apps. Fast by default, accessible, easy to maintain after handover.
Cloud & backend
Authentication, databases, storage and APIs that stay cheap while you are small and hold up when you are not.
UI/UX design
Interface design that respects the person using it. Clear hierarchy, sensible defaults, no dark patterns.
Monetisation & growth
Ads and in-app purchases wired up properly, including the compliance files ad networks quietly require.
Maintenance & support
Mobile platforms move whether you do or not. We keep shipped products current and take on inherited code.
Our products
