Your chats, read honestly. Third Eye reads a conversation you already had and tells you what it actually says. Not vibes. Evidence, then a verdict. WHAT PEOPLE BRING IT Who's pulling away. Who cares more. Where this is heading. Why it feels different lately. The things you can feel in a chat and cannot prove. HOW IT WORKS 1. Export a chat from WhatsApp or LINE and open it in Third Eye. 2. Say who they are to you: situationship, crush, partner, ex, best friend, family, or anyone else. 3. Pick how deep to go, and how blunt you want it. EVERY READING GIVES YOU Findings, and every one of them quotes the exact message it stands on. If the Eye cannot point at a real line in your chat, it does not make the claim. Nothing goes on the record without its receipt. That rule is the whole product. A verdict in one sentence you could argue with. A score out of 100, worked out on your phone from who starts things, who replies, and how steady it stays. The numbers behind it: messages, days, reply times, who gets left on read, longest streak, signature emoji. DEEPER READINGS ADD MORE Deep Dive adds a profile of each of you, how you each communicate, what you each seem to be asking for, and one call on where this is heading. GOD Mode adds the whole record: the eras of you two, the turning points, the scenarios ahead and what to do next. IN YOUR VOICE, IN YOUR LANGUAGE Every reading arrives in the voice you pick: Gentle, Straight or Savage. The Eye works out the language of your conversation from the messages themselves, then writes the whole thing in it. ASK THE EYE The Eye already read the whole conversation. Ask it what a message meant, or what to send back, and it answers from that same chat. COME BACK LATER Read the same chat again weeks on, and Third Eye lays the two readings side by side: the score, the stats, the findings that closed and the ones that are new. SHARE THE VERDICT, NEVER THE CHAT Share cards carry the verdict, a number, or the one quote behind a finding. They never carry your conversation. PRIVACY, STATED PLAINLY Real names are stripped on your device before anything is analyzed. Your anonymized chat goes to an AI provider for one job: writing your read. It's never stored on our servers. Your reads and the anonymized receipts behind them live only on your phone. No account, no sign-up. WHAT THIS IS NOT Third Eye reads one exported conversation and nothing else. It cannot tell you what a person privately feels or intends, and it never pretends to. A reading is one honest interpretation of the text you handed it, made for reflection and entertainment. THIRD EYE PLUS Your first read is free. Plus opens up Deep Dive readings and re-reads in another voice, with a set number of readings included each period. The monthly and yearly plans add GOD Mode readings and questions for Ask the Eye. Weekly, monthly and yearly plans are available, and there is no free trial. Rather pay once? Deep, GOD and Ask credits are one-time purchases and need no subscription. Prices and exact allowances are shown in the app before you buy. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the current period ends. Manage or cancel anytime in your Apple Account settings.

HeartCheck

HeartCheck reads the chat you can't stop overthinking. Export the conversation from your messaging app, upload it to HeartCheck and AI listens to the chat's heartbeat: reply times, topic changes, tone, effort balance and the little patterns you feel but can't put into words. In about a minute you get a heart score, the red flags spelled out one by one and the exact messages that raised them. WHAT YOU GET • Heart score: is this chat healthy, rocky or broken? • Red flags and green flags, each explained in plain language • Evidence: tap a flag to see the message that triggered it and why • Decode a message: paste a single confusing text ("my phone was on silent, didn't see it") and get a read on what it really means • Heart diary: your scan history and trend over time. Rescan after a talk and watch the score move • Share cards: post your verdict to your socials with names and photos hidden automatically • Challenges: send a card to a friend and compare who has the healthier chat WHO IT'S FOR Partner, crush, ex, situationship or the group chat that's been weird lately. If you've ever screenshotted a conversation to ask a friend "is this normal?", this is the app. HEARTS Your first scan of the day is free. Full reports cost Hearts, which you buy in small packs as one-time purchases. No subscription, no auto-renewal. PRIVACY • Only the chat file you upload is processed. Names in the file are never written into the report; nicknames stay on your device. • Your conversation is never used for ads or model training and is never shared with third parties. • The uploaded file and the report are deleted automatically within 24 hours. • No account required. HeartCheck is for entertainment. It is not a personality test, a diagnosis or professional advice. The final call is always yours.

Verdict
The clearest difference is ads: HeartCheck at none against Third Eye's shown. HeartCheck also leads on update cadence (every 2 weeks vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
