Clinical software, built small
nrhealthtech builds apps that work offline. Clinical tools that keep working when there is no signal, no wifi and no network at all — because everything runs on the device itself. No accounts, no servers, no analytics.
Everything is on the device. No signal needed, ever.
No server, no sync, no analytics. We never see your data.
No sign-up, no password, no email. Install and start.
Nothing is sold, shared or measured. There is nothing to sell.
The apps
Anaesthesia dose reference
Categorised anaesthesiology drugs with dose per kg and — once you enter a patient weight — the calculated dose beside it, capped at the ceiling where one applies. Age-adjusted MAC, ideal / lean / adjusted body weight, and an 8-step GA walk-through.
Stock & billing for a clinic
A colour-coded stock tracker for tablets, syrups, syringes, nebulizers, respules and general clinic items. Low-stock and expiry warnings on the card itself, per-tablet cost from the pack price, and a bills tab. Category tabs are fully editable.
Getting the apps
Our apps are published on Google Play and available there only. Installing from the store means the usual one-tap install, and updates arrive automatically as we publish them.
Google Play is the only place we publish our apps. Anything offering them from somewhere else did not come from us, and we cannot vouch for what is in it.
Privacy
Our apps have no account, no login, no backend and no analytics SDK. They make no network requests at all — everything, including the drug data and the fonts, is bundled inside the app. Your entries live in your device's own storage and are not readable by us or by any other app. Exports go only where you send them with your phone's share sheet.
Contact
Dose corrections and bug reports are genuinely welcome — email nrhealthtech@gmail.com. If you are reporting a dose, please say which drug, which field, and which reference you are working from.
Not a medical device. Drugs & Doses is an educational quick-reference prepared from standard anaesthesia textbooks. It has not been evaluated by any medicines or medical-device regulator and must not be the primary basis for a dosing decision. Always verify against your own formulary, the patient in front of you, and your own judgement.
