How the Compatibility Quiz Works
The quiz blends proven personality science with practical everyday-living signals. Here is the four-step flow:
1. Sign Up Free
Create a CoHabby account on web, iOS, or Android. There's no payment for seekers and no credit card required. A phone or email is all you need.
2. Answer Lifestyle Questions
40+ short questions about sleep schedule, cleanliness, guests, quiet hours, cooking, pets, work-from-home habits, and shared-space expectations.
3. See Synergy Scores
Every profile you browse shows a 0–100 Synergy Score, broken down by category so you can see exactly where you align and where you might need to talk things out.
4. Message High-Synergy Matches
Messaging is free for seekers. All chat stays in-app until you choose to share contact info. Start with people you're most likely to live well with.
What the Synergy Score Measures
Your Synergy Score is a weighted blend of four categories. Each one predicts a different piece of day-to-day living fit.
Personality — 30%
Communication style, conflict handling, social energy, and MBTI-style signals. This predicts whether you'll talk things out or let tension build.
Lifestyle — 30%
Sleep, cleanliness, noise tolerance, guests, cooking, pets, and work-from-home rhythm. This is the everyday-living layer that breaks most roommate situations.
Interests — 20%
Shared hobbies, weekend patterns, and downtime style. Common interests reduce friction and create the easy low-effort connection that makes shared living feel good.
Housing — 20%
Budget, neighborhood, move-in window, lease length, and property type. Even a perfect lifestyle match won't work if the housing math doesn't line up.
Who the Quiz Is For
People Moving to a New City
Quiz-first matching replaces blind meet-and-greets. Shortlist compatible housemates before you get on a flight.
Post-College Adults
Lifestyle fit matters more after 25. The quiz surfaces sleep schedules, work-from-home rhythms, and quiet-hour expectations that Craigslist can't.
Remote Workers
If you're on Zoom all day, matching someone with a matching quiet-hours expectation saves the relationship before it starts.
Landlords & Primary Leaseholders
Vet potential tenants for fit before tours. Reduce costly turnover by matching housemates who actually want to live together.
Why Compatibility Matters More Than Rent
Most roommate searches optimize for price and proximity. But the research is clear: lifestyle fit is the strongest predictor of whether a living situation lasts 12 months or falls apart in three. A bad roommate match can cost $1,500–$1,750 in turnover alone — lost rent, re-listing fees, lease-break penalties, and moving friction. A high-synergy match removes the most common failure modes before they start.

Frequently Asked Questions
Is the quiz free?
Yes. 100% free for anyone searching. Only landlords pay — subscriptions start at $1.99/month.
How long does it take?
About five minutes. You can skip around and update answers any time.
Is it personality-based or lifestyle-based?
Both. Hybrid scoring outperforms pure personality tests because how you live matters more than how you test.
Can I retake the quiz?
You don't need to retake it — just update answers anytime and Synergy Scores recalculate automatically.
What's a high Synergy Score?
80+ is high-synergy. 90+ is rare and exceptional. Anything below 60 means significant friction points to talk through.
Does it work for co-living and shared houses?
Yes — the quiz works for 2-person apartments, group houses, and co-living spaces. Scores calculate pairwise across the whole household.
