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.
