Add Months is:

  • A clarity tool.
  • Private and local.
  • Based on population-level risk modeling.
  • Designed for re-evaluation over time.

Add Months is not:

  • Medical advice.
  • A habit tracker.
  • A social network.
  • A coaching app.
  • A data collection platform.

Your data never leaves your device.

No accounts required No analytics No ads, ever Encrypted local storage Hard delete = permanent

We cannot see your inputs. We do not collect or sell behavioral data.

Built for Clarity

Most health apps try to optimize everything. Add Months identifies the one lever that matters most — so you can focus your effort where it counts.

Re-run whenever your life changes.
