Download Helix Anesthesia
The free tier is permanent, not a trial — every calculator, every crisis checklist, the full drug library and glossary, three complete regional blocks, five complete surgical cases, and 15 AI questions a month, with no card and no expiry. Sign-in is passwordless: enter your email and we’ll send you a code.
On iPhone and iPad, the App Store app shows each drug’s published dose per kilogram and maximum. Weight-based dose calculation is in the Android app and the browser version: open Helix in Safari and add it to the home screen, where it runs full screen like any other app. The same account and the same free tier work everywhere, including on a computer.
How to install
- Tap the button — it opens the Helix Anesthesia listing on the App Store.
- Tap Get.
- Open Helix and sign in with your email. No password to create.
- Tap the button — it opens the Helix Anesthesia listing on Google Play.
- Tap Install.
- Open Helix and sign in with your email. No password to create.
- Tap the button — Helix opens straight in your browser. Nothing to install first.
- Sign in with your email. No password to create.
- Android: a blue bar appears at the top offering to install it — tap Install. If you miss it, the ⋮ menu has "Install and create shortcut".
- iPhone or iPad: you must be in Safari — Add to Home Screen is a Safari feature, and Chrome, Firefox and DuckDuckGo on iPhone do not have it. In Safari, tap the Share icon, then "Add to Home Screen". Safari never offers this by itself, so you have to go and get it.
- Open it from that icon from now on — it runs full screen, with no address bar.
Do add it to your home screen rather than bookmarking it. On iPhone, Safari clears a plain website’s saved data after about a week of not opening it; an app added to the home screen keeps everything, so your blocks and scans stay available without a connection.
