Dating app algorithm

A dating app algorithm is the system that decides which profiles appear to you, in what order, and how visible your profile is to others. Every major app has one. The specifics are proprietary and change frequently, but the underlying logic of each algorithm reflects one dominant goal: whoever built it decided what to optimise for, and the algorithm pursues that goal every time you open the app.

On the mainstream swipe apps — Tinder, Bumble, Hinge — the goal has historically been engagement. More swipes, more time in the app, more returns. Tinder was publicly reported to use an Elo-style "desirability score" that ranked users by swipe popularity and sorted them into tiers; it stated in 2019 that it had moved away from Elo, though its algorithm continues to weight swipe behaviour heavily. Bumble and Hinge use their own variants, but the structural incentive is the same: an app that makes money from subscriptions and paid boosts benefits from keeping you in the app, not from getting you out of it into a relationship.

This misalignment is the core problem. A swipe algorithm is optimised for the thing that is measurable on the app — a right-swipe, a message sent, a session reopened — not for genuine compatibility. It rewards how well you perform on a feed: how photogenic your lead photo is, how fast you swipe, how many profiles you engage with. These signals predict nothing about whether two people share values, compatible personalities or aligned goals — which relationship science identifies as the strongest predictors of lasting satisfaction.

A compatibility algorithm works differently. Instead of ranking by popularity or rewarding swipe behaviour, it models who you are — your personality, values, lifestyle and what you want from a relationship — and estimates genuine fit between people. It introduces a smaller, more relevant set of matches rather than an endless, engagement-optimised queue. The goal is accuracy, not volume.

Lamp is built around a compatibility algorithm, not a swipe-engagement algorithm. It builds a model of your personality and values, factors in your Wishes — what you describe wanting in a partner in plain English — and introduces a curated few people who genuinely fit, with the reasons shown. Its algorithm is aligned with your outcome: a real relationship. That is the only kind of dating app algorithm worth using.
