Products we
build, own & operate
Heldig Lab is an independent software studio. We build, publish and operate our own portfolio of mobile and web products — we do not take on client work or run advertising for third-party clients.

Everything below describes how we build and operate our own products. Heldig Lab does not take on client development work or run advertising for third parties.
In-House Development
Every product in our portfolio is built in-house — iOS and Android with SwiftUI and React Native, web with TypeScript. We do not take on client development work.
Store Optimisation
We maintain the keyword sets, subtitles and creative assets for our own App Store and Google Play listings.
Self-Funded User Acquisition
We buy app install traffic for our own titles only, on our own advertising accounts. We do not manage advertising accounts belonging to anyone else.
Internal Reporting
Campaign and retention data from our own apps is aggregated into internal reports. No user-level or campaign data is shared with third parties.
Heldig Lab Ads Analyzer
We run Google Ads App campaigns to drive installs for our own apps. To review that spend we maintain an internal command-line tool, the Heldig Lab Ads Analyzer, which reads performance data from our own Google Ads manager account. It is used only by Heldig Lab, is not offered to third parties, and is not available as a hosted service.

About Heldig Lab
Founded in Kyiv, Ukraine, Heldig Lab is an independent software studio. We build, publish and operate our own products across wellness, productivity and learning, and we believe software should be a tool for empowerment, not a source of digital noise.
Our philosophy centers on "Functional Elegance"—where every pixel serves a purpose and every interaction feels deliberate.
Heldig Lab is the publisher of record for every product listed on this site. All advertising we run promotes our own products and is bought through advertising accounts we own and operate ourselves. We do not act as an agency, reseller or marketing service provider for any third party.
