20 minWhat instant actually means
What “instant” actually means here.
20 minutes, from the moment you collect your saliva sample to seeing your result in the Eli app. It’s not immediate — there’s a short processing window — but it’s fast enough to check your rhythm the same morning you test, not days later.

Before you decide
Your questions, answered.
Is 20 minutes really accurate — not just fast?
The 20-minute window is the app’s scan-and-analyze time, not a shortcut on the sample itself. It’s the same saliva-collection and computer-vision process every time.
Do I get a result every single time?
If a test doesn’t produce a readable result, it’s covered by Eli’s replacement guarantee.
Does the app work on Android?
Yes. The Eli app is available for Android on Google Play.
The Eli difference.
