Sub
Read full descriptionHide full description
Sub is designed with the clinical experience and guidance of a couples therapist. Sub is not therapy or a diagnostic tool — it is your own judgment-free space for reflection. Sub is a quiet evening companion for your relationship. No feeds, no chat, no daytime noise. Sub stays silent through the day and listens only at night. When the day ends, you speak for two minutes and mark three simple lines — warmth, time together, closeness. Through the night, Sub weaves what you said into a calm, personal reflection that returns to you in the morning. Your voice is enough. You don't need to form perfect sentences. Sub notices not only what you say, but the tone underneath it — softening, tension, a held breath — and gently mirrors the moment back so you feel seen. WHAT SUB DOES • Nightly voice reflection — two minutes, then a warm morning note • Voice tone observations, never judgment or advice • A single inward question to sit with — never a to-do • Archive & heatmap — see the pattern of your nights over time • Emergency mode — one short minute when a day overflows SUB PRO • Deep Voice Anatomy — the feeling beneath your tone • Memory & detail tracking — quotes that return when they matter • Smart Bridge — an invisible bridge if your partner joins • Relationship Map — a weekly trace on warmth and trust Try 3 days free, then $3.99/month or $34.99/year. Cancel anytime. YOUR PRIVACY Your voice is processed to create your reflection and then deleted — it is never stored on our servers. You can delete your account and all data at any time. Sub is a companion for self-reflection, not a substitute for professional help or medical advice. Available in English, Türkçe, Français, Italiano and Русский.
