What we do

From first build to long-term operation

We build software, publish it and keep operating it after launch.

  • Mobile applications

    Cross-platform apps for iOS and Android, primarily built with Flutter, which we publish and maintain ourselves.

  • Web products

    Websites, web applications and the backend services that our apps rely on.

  • AI-enabled software

    AI features where they do real work: generated video content, personalised interpretations and draft analysis.

  • Product operations

    Releases, support, store listings, privacy policies and account deletion. We maintain what we ship.

  • Distribution & growth

    We test distribution channels for our own products, from store listings to search.

Technology

A small, deliberate stack

We choose tools that let us ship and maintain several products in parallel, and we keep the number of moving parts low.

Flutter & Dart
Our main framework for cross-platform iOS and Android apps.
Web technologies
Web front ends, web applications and content sites.
Backend & cloud
Cloud-hosted services behind our apps, including Firebase, databases and push notifications.
APIs & integrations
Connecting products to third-party platforms and data sources.
Automation
Automated content and data pipelines, such as regularly updated statistics.
AI-assisted engineering
AI tools in our development workflow, and AI models integrated into products.

New business area

B2B software discovery and SaaS partnerships

We are expanding from our own apps into helping businesses find and compare software — and into long-term, transparent partnerships with the software companies behind it. This area is new for us, and we are building it step by step.

Partnership details

  • Search engine optimisation

    Pages that answer software-selection questions well enough to rank on their own merit.

  • Selection & comparison content

    Structured comparisons and shortlisting aids that help buyers decide, not just click.

  • High-intent paid search

    Search campaigns on non-brand queries where businesses look for a type of software, only where a programme’s terms allow it.

  • English-speaking markets first

    Our initial focus, with further markets once the approach has proven itself.
