💡 Inspiration

Modern agricultural research shows that most pesticides lose efficiency in alkaline water (pH > 7.0) and perform best in slightly acidic or neutral conditions.
However, farmers often lack accessible, science-based tools to manage spray water pH precisely.

AquaTune was created to solve this — a scientifically accurate, easy-to-use tool that empowers farmers to optimize spray tank water chemistry using safe, acidifying fertilizers.
Our goal: enhance pesticide performance, protect crops, and make precision agriculture accessible to everyone.

⚙️ What It Does

AquaTune calculates the exact fertilizer amount needed to bring spray water into the ideal pH range based on user inputs.

🧠 Scientific Engine

  • 🧪 Advanced Chemistry Models — Henderson–Hasselbalch equations & carbonate equilibrium
  • 🌱 Nitrification Modeling — Simulates biological acidification via ammonium oxidation
  • ⚠️ Precipitation Risk Assessment — Predicts calcium phosphate & sulfate precipitation
  • 🔍 Multi-Parameter Analysis — Considers water hardness, temperature, alkalinity, and fertilizer purity

The result: accurate, science-driven water conditioning recommendations in seconds.

🛠️ How We Built It

We built an ecosystem, not just an app:

  • 🌐 Web Application — React + TypeScript + Tailwind CSS for fully responsive design
  • 📱 Android App — Native Kotlin + Jetpack Compose with full offline capability
  • ⚙️ Shared Core Engine — Identical scientific models across both platforms

Together, they bring lab-grade chemistry models directly to the field.

🧩 Challenges We Ran Into

  • Implementing robust, real chemical equilibrium computations required deep study of agricultural chemistry and carbonate systems.
  • Learning Kotlin and Android app development from scratch to achieve production-ready quality.
  • Designing a responsive, bilingual interface for both scientists and farmers.

🏆 Accomplishments We’re Proud Of

  • ✅ Built a fully functional cross-platform ecosystem (Web + Android) for precise water chemistry adjustment.
  • 🔬 Developed a scientific-grade pH prediction engine using true equilibrium chemistry.
  • 🌍 Delivered a multilingual interface (English, German, Spanish, Ukrainian) to make agricultural science globally accessible.

📚 What We Learned

  • Advanced fertilizer and water chemistry interactions
  • Kotlin, Gradle, and Jetpack Compose for Android
  • Tailwind CSS and modern responsive web design

🚀 What’s Next for AquaTune

  • 📲 iOS App for full cross-platform reach
  • 💰 Real-time fertilizer pricing by region and currency
  • 🌾 Expanded fertilizer database with specialty nutrients
  • 🌤️ IoT integration for automated water quality and pH monitoring

🌱 Impact

AquaTune promotes precision agriculture by reducing chemical waste, improving pesticide effectiveness, and lowering costs — empowering farmers with science they can trust.
