AI-Guided Mental Wellness & Movement Coaching
Spanish-language AI wellness platform: guided sessions, sleep and anxiety training, 24/7 personal coach
The problem
Mental-wellness apps in Spanish-speaking markets are largely translated afterthoughts: English products with Spanish subtitles, generic meditation libraries and no personalisation. Minduo wanted the opposite: a natively Spanish product where an AI coach adapts to the individual, a structured 21-session programme replaces an unstructured content dump, and mental wellness is paired with physical exercise. It also had to feel like a native mobile app while remaining instantly accessible on the web, and had to be fast enough that a five-minute daily habit is never interrupted by a loading screen.
How we built it
8 decisionsDesigned the platform around a structured, cyclical 21-session curriculum so users follow a programme with a beginning and an outcome, rather than browsing an infinite content library.
Built a 24/7 conversational AI coach that carries context between sessions, so guidance reflects the user’s history, mood entries and progress instead of restarting each time.
Integrated guided audio delivery and voice-led sessions for sleep, night-time anxiety and breathing practice, plus guided physical-exercise routines that complement the mental training.
Implemented an onboarding assessment that establishes a baseline and personalises the programme path from day one.
Delivered a Progressive Web App so the product installs to the home screen and behaves like a native app without app-store friction, while remaining fully indexable and shareable.
Engineered a Redis caching and queue layer so session content, streaks and coach context resolve instantly even under concurrent load.
Built the entire experience natively in Spanish: copy, tone, content and voice, with an internationalisation framework ready for additional locales.
Implemented a trial-to-subscription funnel with lifecycle messaging designed around habit formation and retention.
