About this app

ChemLab is your pocket laboratory assistant, built for students, researchers and lab technicians. Every essential chemistry calculation, two taps away — 100 % offline, no account, no connection required.

⚗️ QUICK CALCULATIONS
• Molarity: C = n / V (leave any field blank to solve for it)
• Dilution: C1·V1 = C2·V2
• Conversions: grams ↔ moles, mg/L ↔ ppm, % m/V

🧪 STEP-BY-STEP LAB ASSISTANT
• Prepare a solution from a chemical formula (e.g. NaCl, H2SO4, Ca(OH)2)
• Guided dilution with full procedural instructions
• Concentration adjustment: too dilute or too concentrated → fix

🔬 ADVANCED CHEMISTRY
• pH: strong acids/bases, weak acids (Ka), Henderson-Hasselbalch
• Stoichiometry: limiting reagent, % yield
• Ideal gas law PV = nRT
• First-order kinetics, half-life
• Radioactivity: decay, t½, activity (Bq)
• Formula parser: Al2(SO4)3, CuSO4·5H2O

📚 LOCAL HISTORY
Every calculation is saved on your device — nothing leaves your phone. Browse, delete, reuse.

🌐 BILINGUAL EN / FR
Switch language with a single tap.

✨ MODERN DESIGN
Clean interface, soft gradients, intuitive navigation. Works on Android 7.0+.

ChemLab is free and ad-supported. Thank you for keeping the app alive!
