Inside the report
What's in your ChatChemistry report?
Every card is built from patterns in your chat export — counts, timing, emojis — and never sends your messages anywhere. Here's what you get.
Love Score
A playful headline score out of 100, built from the affection, energy and balance signals in your chat.
Chemistry type
One of seven archetypes, from Certified Lovebirds to Midnight Sweethearts, picked from how your conversation actually flows.
Who talks more
The message split between you two, and who usually gets the conversation going again after a quiet stretch.
Reply spark
How quickly you answer each other, turned into a reply score out of 10.
Texting personas
How each of you texts: The Novelist, The Dry Texter, The Double-Texter, The Fast Replier and more.
Green flags
Three good things your chat really shows, like balanced effort or nobody being left hanging.
Chat streak
Your longest run of consecutive days where you both texted.
Top emoji, peak hour & timeline
Your signature emoji, the hour you chat most, and how your conversation grew over time.
Relationship lenses
Not a couple? Pick partner, crush, best friend, family or colleague, and every label changes to fit.

Questions
Questions, answered.
What is ChatChemistry?
ChatChemistry is a private WhatsApp chat analyzer for Android. It reads a two-person chat export on your phone and turns it into a playful relationship report: a Love Score, your chemistry type, texting personas, green flags and shareable cards. Think of it as a Wrapped for your conversation, made for couples, crushes and best friends.
How do I export a WhatsApp chat?
Open the two-person chat in WhatsApp, tap the ⋮ menu, then More › Export chat, and choose Without media. In the share sheet, pick ChatChemistry. You can also save the .txt or .zip file and open it from the app; exports up to 50 MB work.
Does ChatChemistry upload my messages or use AI?
No. Your chat is read and scored on your phone. There is no account, no server and no AI chatbot reading your conversation; the report keeps aggregate numbers like message counts and reply times, never the messages themselves.
Is it free? How much does it cost?
The app is free to download, and you can open a full sample report before importing anything. On your own chat, your chemistry type and green flags are free. A single one-time purchase unlocks every card — no subscription, no renewals.
Does it work for friends, family or a crush?
Yes. Before your report is built you choose a relationship lens: partner, crush, best friend, family or colleague. The numbers stay the same, but the labels change to fit, so between friends the Love Score becomes a Hype Score.
How accurate is the Love Score?
The numbers behind it are real: message counts, reply times, emojis and the hours you chat are all measured from your export. The score and the archetype are a playful reading of those patterns, though, not a measure of how anyone feels. ChatChemistry is for fun, not relationship advice.
Which chats and phones are supported?
Two-person WhatsApp chats, exported as .txt or .zip, on Android phones through Google Play. Group chats aren't supported. The app is available in English, French and Spanish.
