What metric would you pick as the north star for a meditation app?

How to approach it

Ask what outcome users want, which is usually feeling calmer or sleeping better, then find a behavior that predicts it.

How a strong answer opens

“People come to a meditation app to feel calmer or sleep better, which we can't measure directly. So I'll look for a behavior that predicts that outcome.”

Outline of a strong answer

Try answering out loud for a few minutes before you open this.

  1. Name the user outcome: less stress, better sleep
  2. Rule out vanity picks like downloads
  3. Propose weekly users completing at least three sessions
  4. Explain why frequency predicts both benefit and retention
  5. Guardrail: self-reported mood, so streak pressure does not backfire
  6. Inputs: onboarding completion, reminder opt-in, session variety

Where this question usually goes wrong

Picking downloads or streak length without asking whether they reflect the calm or better sleep users actually came for.
