Groov
Mental Wellbeing for iOS & Android
We were the primary engineering partner for Groov's cross-platform mental wellbeing app — delivering interactive wellness tools, guided mindfulness experiences, mood tracking, and AI-assisted personalisation across iOS and Android using React Native.
01
Overview
Groov is a mental wellbeing platform that helps users build healthier emotional habits through guided wellness experiences, mindfulness tools, and personalised support. Techwondoe served as the primary engineering partner, contributing to major parts of the cross-platform mobile application for iOS and Android.
The app was designed to make mental wellbeing support more accessible and engaging through interactive daily tools, guided exercises, wellbeing content, and personalised user experiences. Our team focused on delivering a smooth, scalable, and reliable cross-platform experience using React Native with native mobile integrations.

The challenge
Groov needed a primary engineering partner to build and ship major features for their cross-platform mental wellbeing app — with the quality bar of a wellness product where unreliable experiences directly undermine user trust. The challenges went beyond software: audio had to feel smooth, interactions had to feel calm, and releases had to be fast without regressions across a wide device matrix.
01
Delivering frame-accurate audio for guided wellness experiences in React Native
02
Maintaining a stable, regression-free experience across iOS and Android
03
Rapidly shipping new wellbeing tools without breaking existing functionality
04
Building UX that communicates calm and safety through every micro-interaction
05
Establishing test automation to reduce manual regression burden
03
Approach
We embedded as the core engineering team, focusing on quality, platform stability, and a development cadence that let Groov ship confidently. Native modules were used where React Native’s bridge couldn’t meet the experience bar, and Detox E2E testing was invested in from the start.
01
React Native foundation with native audio modules
Established the React Native + TypeScript architecture with Redux for state management. Native iOS and Android audio modules implemented to achieve frame-accurate control that the JS bridge couldn’t deliver.
02
Detox E2E test suite covering all critical journeys
A comprehensive Detox-powered E2E automation suite was built in parallel with feature development — covering all critical user journeys and enabling confident releases across both platforms.
03
12+ wellness tools shipped to production
Guided breathing, sound mixer, kindness generator, mood tracking, and personalised recommendations — all shipped as stable, production-ready features integrated into the live app.
04
Performance improvements and crash rate reduction
Crash monitoring integrations, performance profiling, and systematic fixes resulted in measurably reduced crash rates across the iOS and Android device matrix.
04
Tech stack
We built on a React Native foundation with TypeScript throughout, leveraging the Expo ecosystem for tooling while dropping into native iOS and Android modules for performance-critical features like audio and push notifications.
