Tools & calculators

Practical tools built to remove math errors, improve consistency, and make dosing decisions clearer—not more complicated.

Why these tools exist

Most dosing mistakes aren’t caused by bad intentions—they’re caused by mental math, unit confusion, and inconsistent setups.

InjectBuddy tools are designed to standardise calculations so you can focus on execution, not arithmetic.

Principle

If the math is wrong, the dose is wrong.

Core calculators

Supporting tools

  • Syringe visual guides
    Visualise insulin syringe markings to reduce draw errors.
  • Injection frequency planners
    Compare weekly vs every-N-day injection schedules.
  • Unit conversion helpers
    Reduce mg, mcg, mL, and IU confusion.

How to use these tools correctly

  • Confirm vial strength before entering values
  • Understand dilution before trusting outputs
  • Match syringe type to the calculator
  • Recheck numbers if anything looks unexpected
Rule

Tools support understanding—they don’t replace it.

Common calculator mistakes

  • Entering total vial amount instead of per-mL concentration
  • Confusing mg and mcg
  • Using the wrong syringe scale
  • Changing dilution mid-vial without recalculating
Pattern

Bad inputs produce confident-looking wrong outputs.

Learn before you calculate

Key takeaways

  • Calculators reduce math errors—not judgment errors.
  • Correct inputs are more important than fancy outputs.
  • Consistency beats recalculating every injection.
  • Understanding always comes first.
