How it works
There are four steps, and none of them share your real location. Below we also show the maths behind each one — because calling an algorithm “smart” is easy, showing what it does is not.
Four steps
- 1
Answer questions
Questions are grouped into categories. Only the core category is required at sign-up — four questions. You open the rest whenever you like, in any order. The more you answer, the sharper your matches get.
- 2
Pick your interests
From climbing to pottery, chess to freediving. If something is missing you can suggest it; suggestions join the pool after review.
- 3
See your compatibility
Compatibility is not one-sided. It is not enough that you like their answers — they have to like yours too. If you have dealbreakers, a mismatch there ends the match entirely.
- 4
Meet
See compatible people nearby, send a connection request, start talking. A single screen for seeing and accepting incoming requests is still on the way. On the free plan you can start one conversation a week; replying to a message you receive is never capped.
Why “same answer” does not mean compatible
The first design matched people who gave the same answers. That produces the wrong result, because questions are not all of the same kind.
- Some questions call for similarity: life priorities, communication style.
- In others difference is valuable; on some axes being complementary works better.
- Some are dealbreakers: smoking, pet allergies. A mismatch cancels the match outright.
- Some are informational only; they show on your profile but never enter the score.
So every question carries an axis, and the score is the geometric mean of both sides' satisfaction. With an arithmetic mean, a pair where you are delighted and they are not at all would land in the middle. The geometric mean punishes one-sided satisfaction hard.

Get notifiedThree questions will not give you 100%
Someone who answered a handful of questions appearing at the top would destroy your trust in every percentage you see. So the question part of the score is trimmed by a confidence factor: the more questions you have both answered, the closer it gets to 1; when there are few, it pulls the question part down. The factor is not applied to the interests part.
With three questions in common the confidence factor is 0.27; the question part is trimmed by that much. The factor is adjustable from the admin panel, without shipping code.
A rare interest tells you more
In a friendship app, overlapping interests are as strong a signal as question compatibility. But “listening to music”, which almost everyone picks, should not score like “bouldering”: overlap is weighted by rarity.
The default split is 65 per cent questions, 35 per cent interests. That ratio is adjustable from the panel too.
Location: your real position is never on the map
This is not a marketing line, it is a rule built into the schema. The detail is on the location privacy page.
Raw coordinates are not stored
Your location is rounded to three decimal places (about 110 metres) before it is saved. A database trigger enforces this — even if the app tried to write full precision by mistake, it would be corrected.
The point shown is offset
The map point sits inside a roughly 3 km cell, placed with a fixed offset derived from your account. Fixed matters: if it were random, someone querying you repeatedly could average the readings and recover your real position.
Distance comes back as a range
Something like “under 5 km”. A decimal distance would allow triangulation from a few points.
The density view leaves out sparse cellsOn the way
The density view drops any cell holding fewer than five people from the response. That threshold is defined for that view only, not as a general rule. The density view is empty for now; it will be switched on once it is ready.

Frequently asked questions
Is it a dating app, is it free, when does it launch?
Meet people who like what you like
Ruh Eşi is not a dating app. It exists so you can meet people to hike with, listen to the same band with, and talk about the same thing for hours — and your exact location is never shown on the map.
