Nutrient Calculator App Design

House & Garden Nutrients, a respected name in plant nutrition, needed a way to modernize how growers interact with their multipart feeding schedules. Paper charts were outdated, prone to error, and difficult to use in real-world growing environments—especially where internet connectivity could be limited.

As a freelance designer and digital strategist, I partnered with House & Garden to conceptualize, design, and deliver a nutrient calculator app that turns complexity into simplicity—empowering growers to get better results with less hassle.

House & Garden needed a solution that could:

• Replace cumbersome paper mixing charts with an intuitive digital tool
• Handle complex nutrient calculations across different crop stages and reservoir sizes
• Offer offline functionality for growers working in remote environments
• Enhance brand loyalty by embedding their expertise into daily cultivation practices

The tool had to be accurate, reliable, and effortless to use—no matter where growers were working.

I designed a clean, mobile-first app interface that made nutrient management easy:

• Simple User Inputs:
  Growers enter their reservoir size, base nutrient, and growth stage durations to generate custom feeding schedules.
• Saved Profiles:
  Users can save different crop setups as Profiles, making it easy to manage multiple growing operations without re-entering data.
• Offline Access:
  The app was engineered to function both online and offline—critical for growers in rural areas.
• Streamlined UX/UI Design:
  Focused on minimalism, speed, and clarity, ensuring even non-technical users could navigate and benefit from the app immediately.

The result was a powerful tool wrapped in an intuitive, brand-aligned interface.

The launch of the House & Garden Nutrient Calculator App:

• Simplified nutrient planning for growers of all sizes
• Eliminated common errors associated with manual calculations
• Deepened brand loyalty by offering tangible daily value
• Strengthened House & Garden’s position as an innovative leader in plant nutrition

The app quickly became a must-have tool for House & Garden customers—transforming nutrient management from a challenge into a competitive advantage.

“The mobile app developed by Andrew has been a game-changer for our customers. Andrew’s innovative approach has not only made nutrient mixing foolproof but has also deeply ingrained our brand in the daily practices of growers. This tool has strengthened our market position and customer loyalty immensely.”
