Install

  1. Open Grid Down from the home screen (or app list) once while online, and open both tools, so everything is saved to the device.
  2. In Medical, go to Drug lookup and tap Download all FDA labels on Wi-Fi.

Keep it current

Open the app on Wi-Fi now and then; updates install automatically. Everything you enter (weights, dose logs, checklists) stays on this device only.

Reference only. When any doctor, pharmacist, or emergency service is reachable, use them first.
