Heart Knows
Read full descriptionHide 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/

Verdict
The clearest difference is in-app purchases: grug at none against Heart Knows's 3. Heart Knows's advantage is update cadence (daily vs weekly) and device support (3 vs 1). On price and ads there is nothing between them.
