Mojo Upgrade is a great tool — but it's not the only one. Below are four free, web-based alternatives, compared on what each one actually does today. No invented features, no invented pricing.
Last checked: October 1, 2026, against each site's own pages. Also see our direct Uncover Passion vs Mojo Upgrade comparison.
Mojo Upgrade pioneered a simple idea: both partners privately answer a long list of intimate questions with "yes," "no," or "maybe" — and anything either person said no to never comes up. It's the digital version of the yes/no/maybe list that couples have long written out on paper, and it removes the hardest part: saying the awkward thing out loud first.
One detail worth knowing before you pick a tool: Mojo Upgrade doesn't only reveal mutual yeses. A "yes" from one partner paired with a "maybe" from the other is also shown, so the two of you can talk it through — the maybe never gets pushed on you, it just becomes visible.
Different couples want different things — a broader question set, a format that isn't one giant checklist, or the option to explore solo before comparing. How we compared: format, cost (per each site's public listing), and the matching mechanic.
A free online questionnaire built around the classic format: run through a list of questions and scenarios, and your partner does the same separately.
A free questionnaire for couples with a different angle: it's built to surface new things to try, not just confirm what you already share.
A free kink test that works solo or as a duo — useful when one of you wants to figure out your own answers first.
A freemium option with a modern flow: swipe through cards to build your profile, then match privately with a partner.
Uncover Passion is built on the same private-matching idea: you each answer intimate questions separately on your own device, and nothing either of you said no to is ever suggested. But it works differently in a few ways that matter:
Your answers are shared only with the partner you invite.
Any quiz that uses the same private-matching mechanic: both partners answer separately, and anything either person said no to stays invisible. The four options above, plus Mojo Upgrade itself, all work this way.
Each site handles privacy differently — check its policy before answering anything personal. At Uncover Passion, your answers stay between you and the partner you invite, and the results page is what shows each other's answers — there's no separate feed where answers leak out.
Yes. All four options above have a free tier; Comparekink charges a one-time fee to unlock all matches, and KinkMatch.app offers optional paid upgrades. Uncover Passion's 10-question starter is free, with a one-time $19 pass for the full 196-question library.
The matching part does depend on two private answer sets being compared. With Uncover Passion, one person can start the free starter solo and invite their partner when they're ready, so nobody is stuck waiting with an unfinished quiz.
