From Skin Bliss to the studio model

Bliss Labs is a mobile application studio based in Barcelona, founded by Dr. Maria Otworowska and Dr. Marvin Uhlmann. Both founders carry academic backgrounds (PhDs) and a history of scaling consumer technology. Their previous venture, Skin Bliss, reached a seven-figure user base by applying data-driven insights to skincare. Bliss Labs represents a shift toward a studio-style model, where the founders apply their development formula across multiple verticals including productivity, education, and personal health.

The company does not build a single general-purpose assistant. Instead, they develop specialized apps that use AI to solve specific "everyday frictions." This strategy prioritizes immediate utility over general intelligence, placing Bliss Labs on the consumer-facing end of the agent stack. By focusing on niche apps rather than broad platforms, they bypass the high compute and data acquisition costs associated with foundation models, opting instead to build specialized agents on top of existing LLMs.

The specialized agent portfolio

Their current product lineup highlights three distinct areas of focus: language tutoring, health management, and task automation.

Spanish Class is the most agentic of their offerings. It is an AI language tutor that provides adaptive learning and personalized coaching. Unlike traditional gamified apps that rely on static trees, Spanish Class uses LLM-driven interaction to provide structured lessons and real-time support. This is a personal language coach that adjusts difficulty and curriculum based on user performance.

Biome Bliss addresses the gut health market by acting as an AI-powered guidance tool. Its primary differentiator is its verification layer: it checks food health claims against EU-verified scientific standards. The app connects to Apple HealthKit to link dietary input with real health data, providing a more objective feedback loop than standard calorie trackers. This product is currently in a waitlist phase, signaling a controlled rollout typical of scientifically-backed utilities.

Deep integration with the Apple stack

For productivity, Bliss Labs offers N-day, a recurring task tracker. While task managers are a crowded category, N-day targets tasks with irregular intervals—those that occur every 45 days, for example, rather than every Tuesday. The app relies on deep integration with the iOS ecosystem, utilizing Siri Shortcuts, iCloud sync, and Apple Reminders.

This platform-specific focus is a core part of their strategy. By building into the Apple system, Bliss Labs ensures their apps behave like native features rather than isolated silos. For users, this means they can interact with Bliss Labs' tools via voice or native notifications, reducing the friction usually associated with opening a dedicated app. The studio operates with a small, two-person team, emphasizing high-leverage development and the use of AI to maintain a broad portfolio without the overhead of a large organization.
