    Our verdict

    These aren't really competitors. Oura is right if you want passive biometric data. Moody Month is right if you want to understand your patterns without a wearable.

    Choose Oura if\n- You want passive tracking (no logging)\n- Perimenopause and temperature shifts matter\n- Sleep data is important to you\n\n### Choose Moody Month if\n- You want to understand emotional patterns\n- You're not ready to spend £349\n- You want clinician-written education alongside tracking
