Dosage

EDUCATIONAL SIMULATOR ONLY: Not for clinical use or medical decision-making. Practice complex concentration, rate, and conversion calculations — anytime, anywhere. Dosage is a focused training simulator for students, researchers, lab technicians, and anyone who needs to build fast, reliable calculation skills. Convert between volumes, relative amounts, and rates instantly. Build a custom practice library and test your speed with adaptive challenges. All on your device, with zero internet required. SIMULATED CONVERSIONS Select a concentration and watch single and rate-based conversions update in real-time. Flexible Units: Switch freely between mass units (µg, mg, g, kg, I.E.). Volume & Mass: Calculate by volume (mL, L) or mass-relative amounts (per kg). Time-Based Rates: Adjust instantly per hour, per minute, or per second. Customizable: Add as many conversion rows as you need to simulate complex scenarios. INTERACTIVE CHALLENGES Put your knowledge to the test. Challenge mode presents randomized calculation problems with progressive difficulty. Instant Feedback: Correct answers advance your streak to build confidence. Learn from Mistakes: Incorrect answers reveal the full formula breakdown and step-by-step solution. SANDBOX SIMULATION (QUICK PRACTICE) Need a custom concentration on the fly? Enter any mass and volume combination to simulate a custom scenario. Set a target concentration and let the app calculate the missing variables. Lock either the amount or volume and adjust the other — perfect for exploring "what if" scenarios safely. YOUR MOCK PRACTICE LIBRARY Create custom entries organized by color-coded categories. Detailed Entries: Store multiple concentrations per item with dilution details and notes. Share & Backup: Import and export your library as .dosage files to share with study groups or back up your work. BUILT FOR PRIVACY Your data belongs to you. No account required. No analytics or third-party tracking. No ads. 100% offline. All data stays entirely on your device. (Note: Dosage is purely an educational tool and simulator. It is not intended for clinical application, real-world use, or treatment decisions of any kind.)
