Many modern health apps require an account, cloud connectivity, and telemetry just to calculate basic formulas. We designed Nod with a strict privacy-first, zero-cloud architecture everything stays on your device with no trackers.

• Would you like to see exportable local backups (e.g., encrypted JSON/CSV), or is zero-setup local persistence enough?

• What other privacy-first health tools do you rely on daily?

Most sleep trackers give you an arbitrary score out of 100 based on overnight movement or heart rate, but they don't answer the most critical question: How much biological sleep do you owe your body, and how do you pay it back safely?

With Nod, we focused strictly on a rolling 14-night window to calculate net sleep debt and build mathematical recovery schedules.

Questions for the community:

• How do you currently track or handle sleep deficit after a rough week?

• Do you find single-night sleep scores helpful, or do they just trigger sleep anxiety (orthosomnia)?

Hi everyone! Now that Nod is live, we re focused on keeping the app as lightweight and distraction-free as possible while making sleep recovery truly actionable.

We d love to hear from the community:

1. Do you prefer fully manual logging (keeping it 100% offline and battery-friendly) or would you prefer opt-in local sync with Google Health Connect?

2. What sleep metrics actually help you feel better during the day versus just adding cognitive noise?
