Main Square is an independent app publisher based in Lisbon, Portugal. We design, build and maintain our own mobile products.
We believe that great software should be simple, intuitive, and built to last. Our mission is to create mobile applications that solve real problems and enhance people's daily lives.
We focus on long-term value over trends, and on clarity over complexity. Every product we launch reflects that commitment.
Founded
Main Square was founded in 2026 in Lisbon, Portugal, with a clear vision: to build mobile applications that prioritize user experience and long-term value over fleeting trends.
As a solo-founded company, we keep things focused — one product at a time, with full ownership from concept to release.
We believe the best solutions are often the simplest ones. We remove unnecessary complexity to create intuitive experiences.
Every line of code, every design decision, every user interaction is crafted with attention to detail and commitment to excellence.
User privacy is not negotiable. We build applications that respect user data and provide transparency in how information is handled.
We design for the long term. Our applications are built on solid foundations that can evolve and adapt as technology advances.
