Relationship Calculator Help Documentation

A complete guide to the Relationship Calculator, from the first bond to the games for two.

Last Updated: November 12, 2026

1. Getting Started

The Relationship Calculator has three tabs under the heading: Calculate (two names, a relationship and a result), My circle (every bond you calculated) and Play (games for two). Everything happens on this page; nothing is uploaded and there is no account.

Type two names in Person one and Person two (up to 24 characters each). A band of coloured threads starts weaving as you type. Choose the relationship, then press Calculate this bond, or choose Or answer 5 questions for a reading that uses your answers.

2. Choosing the Relationship

Over 70 relationships are sorted into seven groups (Love, Family, Relatives, Friends, Work, Rivals and More), with the twelve most chosen under Popular. The search box finds them by any word of their name and by everyday words such as mom, dad, granny, bestie, coworker, boss, bro, sis, in law or nemesis, and by the start of a group's name. Something else, under More, lets you name your own relationship (up to 30 characters), which is then read like a general bond. If nothing matches a search, a link offers to name it yourself.

3. Your Result

• The score counts up to its number, with its label (Bond strength, Rivalry heat for rivals, Peace score for exes, Spark for a crush) and a heading from four levels.
• The band weaves in under the score, with a short line about the bond, and for rivals the chance of peace.
• What the score is made of, in a plain sentence, and for rivals and exes a note about staying safe.
• Just for fun: the breakdown: five parts for that kind of bond, one marked as a superpower and one as room to grow (for rivals, the one that runs hottest).
• Room to grow with a small idea for that part, what often makes a bond like this work, a small thing to try (Show another idea) and a message to send (Copy message, Show another message).
• Share bond card, Play together with the same two names, the five questions, suggestions for who to try next, and Calculate another bond.

Every result is kept in My circle. With reduced motion turned on in your device's settings, the score, band and bars appear at once, and there is no confetti. There is never confetti for rivals or exes.

4. How the Score Is Made

Both names are written in small letters; spaces, punctuation and invisible characters (such as a zero-width space pasted from another app) are left out, and letters with accents or vowel signs are written the same way however they were typed. The two names are put in alphabetical order and joined with the relationship, and a fixed formula mixes that into a starting number for a seeded number generator. Its first number gives the score: from 62 to 99 for most relationships, a peace score from 52 to 98 for exes and a rivalry heat from 38 to 99 for rivals. The next numbers spread the five parts around the score, pick the lines and choose the first idea and message. The same two names and relationship always give the same result, in either order.

5. The Five Questions

The questions are made for each kind of bond: couples, family (parents, siblings, grandparents, uncles and aunts, in-laws), friends, work (also mentors, teachers and coaches), rivals, exes and crushes, and a general set for everything else. Pick an answer and the next question follows; Previous question goes back, and Close leaves without saving. Each answer counts from 3 for the first choice down to 0 for the last. Together they make a share from 0 to 1 that sets 55 percent of the score on a range from 55 to 100 (30 to 100 for a rivalry); the name game sets the other 45 percent. The result then says With your five answers, and the answers stay with the bond.

6. The Woven Band

Each name gets one of eight thread colours (when both names would get the same one, the name later in alphabetical order moves on three places). Together the names pick a third colour, the width of each stripe, whether two extra stripes appear and one of five weaves: two chevrons, two diagonals or diamonds. Light cream threads separate the colours. The same two names always weave the same band, in either order, whatever the relationship; with so many possible pairs, some other pairs share a band. The band follows the light or dark theme while you type.

7. The Bond Card

Share bond card draws a picture of 1080 by 1350 pixels on your device: the relationship, both names, the score, the band, the label, the heading and its line, and a footer saying it is a game. Long names are made smaller until they fit. Save picture downloads it as a PNG file named after the two names. Share is shown where the browser offers a share sheet, as on most phones, and opens it; if sharing fails, the line of text is copied instead. On a phone you can also press and hold the picture.

8. My Circle

Every bond you calculate goes to the top of My circle. A bond is the two names together with the relationship, so the same pair as friends and as colleagues are two bonds; calculating a bond again replaces it, and a quick result keeps the five answers you gave before. Each bond shows its band, names, relationship and score, with Open reading, Play and Remove (tap twice). Three numbers sit at the top: the bonds calculated, the top score with its pair (rivals and exes are left out, as their scores mean something else) and how many of the seven groups you explored. The tab shows how many bonds there are.

9. Today's Step and the Badges

Each day, by your device's date, the page picks one of your bonds and a small idea for it from that kind of bond's list. Mark as done when you have done it; the step for the next day comes at midnight. Nine badges follow what you do: First knot (one bond), Five ties, Ten ties, Family tree (three family or relative bonds), Work wise (two work bonds), Peacemaker (a rival or an ex), Deep diver (a reading with the five questions), All-rounder (bonds in five groups) and Kept in touch (three steps done). A badge stays once earned, until Clear my circle.

10. Playing Together

Type the two players' names (or play as Player 1 and Player 2) and choose a deck: Couples, Family, Friends, Work or A bit of everything. Who's more likely deals seven of twelve statements in a random order; press the name of the person more likely, or Both of us, and the final count shows who took it. Play again deals new ones. Talk cards deal the deck's eight questions; take turns answering, with Next card and Previous card, and the deck is shuffled again at the end. Play on a bond, or Play together on a result, fills in both names and the deck that suits the bond.

11. Saved Data and Clearing It

The tool keeps its data in this browser under one name of its own: your bonds, the days you marked a step done, the badges and the name in Person one of your latest bond. Nothing is kept until you calculate a bond or mark a step done. Clear my circle asks first and then removes the bonds, steps and badges; other tools on the site keep their data. A private window, or clearing the site's data in the browser, also starts afresh. When the browser does not allow the page to keep data, the tool still works and says that nothing will be kept.

12. Limits

• Names: up to 24 characters each; your own name for a relationship: up to 30; a search: up to 60.
• My circle: the 200 most recent bonds.
• Steps marked done: the last 400 days.
• Saved data is checked value by value each time the page opens; anything that is not what the tool itself writes is left out.

13. Keyboard and Accessibility

Every button and box can be reached with Tab. The three tabs follow the usual pattern: the arrow keys move between them, and Home and End jump to the first and last. Enter in the first name box moves to the second; in the second it calculates once a relationship is chosen, and otherwise moves to the search. The relationships, groups and answers say which one is chosen. The five questions and the bond card open in windows that keep the focus inside and close with Escape. The score is announced as text for screen readers, and the colours of the two names on the game buttons always reach a contrast of 4.5 to 1.

14. Privacy and Your Data

The names, answers, bonds and steps stay in this browser on this device; there is no upload and no account, and the tool asks no outside service for anything. The bond card is drawn on your device; Save picture and Share hand it to your browser or phone, and nothing is posted by the tool. Like every page on ZeroDataUpload, the page shows ads through Google AdSense and counts visits with Google Analytics; the Privacy Policy explains both.

15. How It Was Checked

Before publishing, the tool's calculations were compared with a separate program written from the rules on this page: 357,276 cases in 14 groups, among them every relationship with all 1,024 ways of answering the five questions, tens of thousands of name pairs in many scripts (the same score in either order, in any capitals, with accents typed two ways and with invisible characters), the thread colours and their contrast, the woven band in both themes, the search, saved data made to break the tool, runs of hundreds of bonds and steps with the badges, today's step in four time zones and the spread of the scores against the formula's own odds. The page itself was then tested in a browser on phones and computers in both themes, with long and hostile names, blocked storage and the keyboard. The original version counted some different names as the same, took names made only of invisible characters, let crafted saved data reach the page, stopped when a saved relationship had an unexpected name, drew long names past the edge of the bond card and had two thread colours with text below the contrast level; that is fixed.

16. Troubleshooting and Support

• The score changed. One letter, a nickname or another relationship makes a different bond. Capitals, spaces and the order of the names do not.
• Calculate this bond says to choose how they are connected. Pick a relationship first, or Something else with a name of your own.
• There is no Share button. The browser offers no share sheet, as on many computers, so the button is not shown. Save picture always works.
• Copy message does nothing. The browser blocked the clipboard; select the message and copy it by hand.
• My circle is empty. It is kept per browser and device; a private window or cleared site data starts afresh.
