The yellow heart on Snapchat is based on a bilateral algorithmic calculation: it appears when two accounts are each other’s number one best friend, meaning that each sends more snaps to the other than to any other contact. This status is not declarative; it is inferred from actual sending volumes over a rolling period.
Custom Snapchat Emojis and False Positives of the Yellow Heart
Snapchat allows users to replace each friend emoji with a chosen symbol in the settings. A user can thus substitute the yellow heart with another emoji or assign the yellow heart to a different tier (BFF, Super BFF, etc.). We observe that this customization often creates confusion: a visible yellow heart next to a contact does not guarantee that it corresponds to the default “Besties” status.

To check if emojis are customized, you need to go to Settings > Manage Additional Features > Friend Emojis. If either account has modified its assignments, the same emoji can reflect two distinct relational statuses depending on the side of the exchange observed.
The asymmetry goes further. The yellow heart is supposed to be mutual by definition, but the customization of emojis breaks this visual symmetry. You may see a yellow heart next to a username while your interlocutor sees a completely different symbol, simply because they have reconfigured their emojis. Before drawing conclusions about the meaning of the yellow heart on Snap, we recommend confirming that both accounts are using the default configuration.

Algorithm for Calculating the Number One Best Friend on Snapchat
The yellow heart is based on a counter of sent snaps (photos and videos), not on text chat messages. Viewed stories, responses to stories, and written messages do not count towards the Besties status calculation. Only direct snaps, sent individually or through a manual selection of recipients, feed the ranking.
The calculation period is not publicly documented by Snapchat, but observed behavior indicates a rolling window of a few days to a week. A sudden change in your sending habits can make the yellow heart disappear in less than 48 hours if another contact takes the top spot.
Hierarchy of Hearts and Temporal Tiers
The yellow heart is the first tier of automatic relational progression:
- Yellow Heart (Besties): you are each other’s number one best friend, with no minimum duration requirement
- Red Heart (BFF): the Besties status is maintained for at least two consecutive weeks
- Two Pink Hearts (Super BFF): the status persists for at least two months without interruption
Moving from one tier to the next requires strict continuity. If the yellow heart disappears even for one day before the two-week mark, the counter resets to zero. The red heart is not obtained by accumulation but by uninterrupted maintenance.
Asymmetrical Exchanges: When the Yellow Heart Does Not Reflect Actual Closeness
The most misleading case involves users who have few active contacts. If a person only sends snaps to two or three accounts, a modest exchange volume is enough to trigger the yellow heart. Meanwhile, the other user may have dozens of regular contacts and consider this relationship only as secondary.
The yellow heart measures a relative ranking, not an absolute volume. Sending three snaps a day to someone is enough to achieve Besties status if that is your most active contact, even if that frequency seems low. The algorithm does not weigh by the total number of contacts or the time spent in conversation.
Group Snaps and Mass Sends
Snaps sent to multiple recipients simultaneously count in the individual calculation of each relationship. A user who systematically sends their snaps to a list of ten people artificially boosts the counter for each of them. This behavior can generate a yellow heart with a contact to whom they pay no particular attention.
We observe that this mechanism regularly produces false positives regarding the actual closeness of a relationship. The yellow heart does not distinguish between a personal snap and a mass-distributed snap.
Disappearance and Replacement of the Snap Yellow Heart
The yellow heart is not a given. Snapchat continuously recalculates the ranking of best friends, and several scenarios can cause its disappearance:
- Another contact surpasses the volume of exchanges with you or with your current Bestie
- You significantly reduce your sending frequency for a few days
- Your interlocutor increases their exchanges with a third party, moving them to another number one best friend
The replacement occurs without notification. Snapchat does not alert you to the loss of Besties status. The emoji simply disappears or transforms into a smiley (😊), indicating that the person remains on your best friends list without holding the top spot.
Difference Between Deletion and Recalculation
Deleting a conversation or blocking and then unblocking a contact resets the history of friend emojis. The yellow heart will only reappear after a new cycle of exchanges sufficient to restore the ranking. In contrast, a simple pause of a few days does not reset the counter: it may be enough to lose the yellow heart if a competitor surpasses it, but the history is not erased.
The yellow heart remains an indicator of flow, not of connection. It reflects who you contact the most via snap over a short window, without considering content, emotional reciprocity, or the total duration of your relationship on the platform. Keeping this distinction in mind helps avoid overinterpreting a symbol whose mechanics are purely quantitative.
