About

Heart Knows

Features
Read full description

A private dating journal and relationship diary for how they left you feeling — before memory rewrites the night. No account. Never a score. Why you need it • After you leave, the feeling is clear. By the next meeting, it is a story. • You will not remember the second meeting the way you felt leaving the first. • Charm, unease, and the no you swallowed get rewritten by the next text. How it feels • The hour after you leave is honest. The story you tell next week is not. • Relief, leftover charm, unease — they deserve a page before they blur. • Quiet enough to tell the truth. Private enough to keep it. Not a verdict on them. How it clarifies your feelings • Your feeling over time, not a ranking. One person. One map. Meetings in a row. • Log the meeting. Then a short check-in a few hours later. • Heart and mind, written apart. They often disagree. • Earlier answers stay hidden while you write tonight. • Name the meeting you will decide by, and up to three things you will not trade. On this phone • No sign-in. No Heart Knows server. • Encrypted on this phone. Restoring from iCloud or Google backup brings it back unless you turn that off in Settings. • Face ID or passcode if you turn it on. A passphrase export only you can open. Meetings, check-ins, and export stay free. Free keeps a rolling 15-day window. Active Journey or Lifetime Keep opens the full timeline, Compare, Patterns, and all twelve sound beds. Heart Knows is a personal memory tool for adults 18+. It is not medical, legal, or relationship advice. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
