A note on safety

DoseRight is a reference tool for trained professionals and students. It does not replace clinical judgement, the medication order, the product label or your facility's policy. Always verify every calculation before administering.

On privacy

There are no ads, no accounts, no tracking and no data collection. Calculations happen on your device and are never uploaded. Network access exists solely so Google Play can validate the optional one-time purchase.
