Pei has shut down. Pei stopped operating on December 30, 2021. Its closing notice told users that Bitcoin balances could still be withdrawn through December 30, and that anything left after that would be cashed out to the payment method attached to the account.
The app listing is gone, the wallet is gone, and the referral code ifppkz does nothing. There is no signup bonus left to claim here.
If you landed on this page looking for a Pei referral code, there is nothing to claim. This page now covers what happened, what it meant for balances people were holding, and what actually replaces the thing Pei did.
What happened to Pei
Pei paid automatic cash back when you spent on a linked credit or debit card, with no receipt to photograph and no coupon to clip first. That was the whole appeal. It was also expensive to run, because it depended on card linked offer networks paying enough for the traffic to cover the rewards.
Pei wound the service down at the end of 2021 rather than keep paying for it. Balances were settled at the time, so there is no account left to log into and nothing left to recover now. No successor app took it over.
What replaces Pei
What made Pei worth having was that it paid you without asking you to do anything at the till. The closest thing still running is Upside, which pays cash back for going to a specific gas station, grocery store or restaurant rather than for buying a particular brand. You claim the offer in the app before you pay, and the cash lands once the transaction clears.
Upside
Get started with Upside and check what it pays at the stations you already use.
If you want a bonus rather than cash back
Cash back is capped by how much you spend, which is part of why Pei never added up to much for most people. These four pay a bonus outright and none of them need a shopping trip attached.
| App | Bonus we track | What you do |
|---|---|---|
| Bigcash | $15 | Games, offers and surveys |
| Freecash | $10 | Offers and app testing, pays in cash or crypto |
| Testerup | $5 | Paid app and game testing |
| Branded | Varies | Surveys, as seen on CBS |
- Bigcash pays the largest of the four at $15 and has the widest mix of ways to earn
- Freecash starts you at $10 and pays out in cash or crypto, with a low withdrawal threshold
- Testerup pays $5 to start and suits anyone who would rather test apps than answer survey questions
- Branded is a survey panel that has been seen on CBS, and is the steadiest of the four
Frequently asked questions
No. No Pei code works, because there is no Pei to sign up for. The service stopped operating on December 30, 2021 and the app listing has been removed, so there is no account for a code to apply to.
No. Pei told users to withdraw before the shutdown and cashed out anything left to the payment method attached to the account at the time. There is no account left to log into and no support line to ask.
Upside is the closest. It pays cash back for going to a specific gas station, grocery store or restaurant, and you claim the offer in the app before you pay rather than scanning anything afterwards.
