What Is Eureka Surveys?
Eureka is a mobile survey app — you answer short surveys about products and opinions, and get paid per survey (typically a few cents up to about $5, depending on the survey’s length and your profile match). It’s built up a large user base over the years and has consistent app store activity, so it isn’t a fly-by-night operation, though like most survey apps you won’t qualify for every survey you’re shown, and payouts are modest for the time invested.
Eureka pays out through PayPal or gift cards once you hit the minimum cash-out threshold in the app. It’s a side-money app, not a job replacement — think “earn a bit while you’re already scrolling your phone,” not “quit your day job.”

Eureka’s Own Referral Program
Once you’re in, Eureka gives you your own referral code to share. When a friend signs up with it, you get a bonus (around 50¢ at last check) once they complete their first survey, plus an ongoing 10% of what they earn on the app, for as long as they keep using it. There’s no cap mentioned on how many friends you can refer, so it can add up if you know other survey-app people.
A note on the numbers: Eureka’s referral bonus is often quoted in cents rather than dollars, and the exact figure moves around a bit between sources and regions. Treat “50¢” as a ballpark, not a promise, and check the in-app terms for the number that applies to your account.
Frequently Asked Questions
Where do I enter the Eureka Surveys referral code?
You’ll be prompted for a referral or promo code during account creation, before you take your first survey. Enter 6F98HM there, or just sign up through our link so it’s applied automatically.
Do I need to complete a survey to get the $1?
No. The $1 bonus is for signing up with a valid referral code. Everything you earn after that comes from actually completing surveys.
How does Eureka Surveys pay out?
Through PayPal or gift cards once you hit the app’s minimum cash-out threshold. Check the app’s current payout minimum before you start, since it can change.
Is Eureka Surveys legit?
Yes — it’s a real, established survey app on both major app stores with a large user base. Like any survey app, expect to be disqualified from some surveys based on your profile, and don’t expect it to replace real income.
When was this page last checked?
We verified Eureka’s app store listings and sign-up/referral terms in July 2026. Referral bonus amounts on survey apps shift often, so double-check the in-app terms before you count on an exact figure.
