iPhone · Safari

On iPhone it installs
from the Home Screen.

Three steps, under a minute. No App Store and no account needed: what you add is the real app, and it then works with no connection at all.

  1. Open the app belowThe button opens it in Safari. If you are reading this in another browser, copy the address and open it there.
  2. Tap ShareThe square with the arrow pointing up, at the bottom centre — top right on iPad.
  3. Choose “Add to Home Screen”Scroll the menu until you find it. From then on Bloody Radar has its own icon, like every other app.
Step 1Open Bloody Radar

It opens in a tab: add it to the Home Screen, then you can close Safari.

After installing

It opens full screen, with no browser bar, and works on a plane just as on the sofa. The data stays on the phone: no account, no server.

Why it is not on the App Store

Publishing there needs Apple's yearly developer membership. Adding it to the Home Screen gives you the same app without going through that.

Safari is required

On iPhone “Add to Home Screen” is a Safari command: other browsers may name it differently, or not have it at all.

This is not a medical app

Bloody Radar records what you write and shows it back to you. It does not diagnose, does not prescribe and does not replace a doctor. Predictions are estimates based on your previous cycles: they are not contraception and must not be used as such. If something worries you, speak to someone qualified.
