FAQ about Dosage Calculation

Are there free dosage calculation apps for iPhone?
Yes — 17 of the top dosage calculation apps we rank are free to download, including CalcuDose and Peptide Calculator & Dosage.
CalcuDose has no ads and offers in-app purchases, according to its App Store listing as of June 2026.
CalcuDose allows you to select the base unit for concentration (g, mg, µg, IU), enter the concentration and desired quantity, and it calculates the result in milliliters with a detailed breakdown. The ml result is rounded to the second decimal place.
For flow rate calculations, you need to select the unit of time (hours or minutes), choose drops per ml, enter the volume in ml, and the duration. The app then displays results in ml/h and drops/min, with a breakdown.
