Road QA Toolkit

Welcome to Road QA Toolkit, the ultimate virtual laboratory for civil engineers, QA/QC professionals, and material testing technicians.

Whether you are on a remote construction site or inside a fully equipped lab, this app provides you with 17 professional engineering tools to calculate complex test results, plot high-precision graphs, and generate instant reports ready for sharing... all completely OFFLINE!

Say goodbye to complex manual calculations and messy Excel sheets. Now you can get your work done with speed, accuracy, and professionalism.

🌟 Key Features:
• 100% Offline Mode: Designed specifically for construction sites with no internet coverage.
• Automated Graphing: The app automatically plots standard curves (CBR, Proctor, Sieve Analysis, Hydrometer) as soon as you input the readings.
• Instant Reporting: Export your test results and graphs as high-resolution images to save or share via WhatsApp and Email.
• Professional UI: Smartly categorized into 'Field Tests' and 'Lab Tests' for quick access.
