App-Leo: Cross-Platform Smart Home Management

Challenge

App-Leo had built a solid reputation in smart home and IT integration, but their customers had no way to manage their systems remotely. Homeowners wanted to control lighting, security, and AV systems from their phones. Contractors needed a dashboard to monitor installations and respond to service requests.

The team needed a mobile app that worked on both iOS and Android, integrated with multiple IoT protocols, and handled real-time device communication reliably.

Approach

Blendly designed and built a React Native mobile application with:

  • Real-time device control via WebSocket connections to IoT gateways
  • Cross-platform delivery for iOS and Android from a single codebase
  • Contractor dashboard with installation status, service alerts, and client management
  • Push notifications for device alerts, maintenance reminders, and system status
  • Intuitive onboarding flow that reduced setup time from 30 minutes to 5

We also designed the REST API layer connecting the mobile app to App-Leo's existing backend infrastructure.

Results

The app launched on both app stores within 8 weeks of kickoff.

  • 8-week delivery from design to App Store and Google Play launch
  • 85% reduction in setup time for new homeowner accounts
  • 50% fewer support tickets thanks to self-service controls
  • 4.7-star rating on both app stores within the first month
  • Real-time reliability with 99.9% uptime on device communication
  • React Native
  • IoT integration
  • REST API
  • WebSockets

Blendly understood our technical requirements from day one. They built an app that both homeowners and contractors love to use. The real-time device controls work flawlessly, and the onboarding flow they designed cut our support tickets in half.
