What if your phone kept earning you money while you slept? It sounds like a scam—but a handful of apps actually do work in the background, earning you money with little to no daily effort.

It’s called passive income, and if you sleep the recommended 7 hours each night, that money has the ability to stack up nicely over time.

In this guide, you won’t find side hustles that require hours of active work. Instead, every app here has a genuine path to earning while you’re not actively engaged. Some are almost entirely set-and-forget. Others require a bit of upfront setup, then run passively from there.

Here’s what’s actually worth your time.

What Does “Make Money While You Sleep” Really Mean?

Let’s be honest about this. There are two types of “passive” earning:

• Truly passive: You set it up once, and the app runs on its own. No daily input required.
• Front-loaded passive: You do work upfront (building a referral network, setting up an investment account), and then money trickles in without additional effort.

Both are legitimate. But if you’re searching for apps that make money while you sleep, you deserve to know which category each one falls into so there are no surprises.

Every app below has a clear passive earning path—and none require much daily active work to keep the money flowing.

Apps That Make Money While You Sleep

Not all of these apps work the same way—some run entirely in the background, while others just need a little setup before the earnings take care of themselves. Either way, every option has a genuine path to earning without daily effort. Here’s where to start.

Earn Passively Through KashKick’s Referral Program

KashKick is a rewards platform where members earn cash by playing games, taking surveys and claiming deals. It’s a great way to turn free time into extra money. But here’s the part that earns while you sleep: the referral program.

When you refer a friend to KashKick, you earn 25% of everything they make from games and deals—for life. You do the work once (sharing your link), and the earnings stack up in the background every time your friend completes an offer.

That’s one share on social media, a text to a friend or a mention in a group chat. From there, every level they beat and every deal they complete puts money in your account without you lifting a finger.

Referral earnings go directly to your KashKick balance. Once you hit $10, you can cash out through PayPal, Venmo or gift card.

Want some surefire strategies to up your passive rewards? Start with these 8 refer-a-friend strategies.

Key features:

• Earn 25% of friends’ game and deal earnings—for life
• No ongoing effort required after sharing your referral link
• Cash out via PayPal, Venmo or for a gift card starting at $10
• Quick payouts: 1-3 business days

Best for: Anyone who can share a link. The more people you refer, the more passive income you build.

Share Your Bandwidth With Honeygain

Honeygain is about as close to “do nothing” earning as it gets. You install the app, leave it running in the background, and it sells your unused internet bandwidth to businesses for market research, ad verification and web intelligence.

You don’t notice it. Your connection doesn’t slow down meaningfully. And small earnings accumulate while you sleep, work or do literally anything else.

Once you hit $20 (around 200GB shared), you can cash out through PayPal or for crypto. Earnings are modest—typically a few dollars a month—but it’s one of the only apps that requires zero daily interaction once set up.

Key features:

• Runs silently in the background on phone, tablet or computer
• Shares unused internet bandwidth only
• Cash out at $20 via PayPal or crypto
• Available on iOS, Android, Windows and Mac

Best for: Anyone with a consistent internet connection they’re not fully using.

Get Paid for Your Data With Nielsen Computer & Mobile Panel

Nielsen Computer & Mobile Panel pays you simply for registering your devices. Install the app, leave it running and Nielsen passively tracks anonymized browsing data to help brands understand consumer behavior.

In return, you earn up to $60 per year per device enrolled in the panel. You’re also entered into monthly sweepstakes just for participating. It’s one of the most hands-off earning methods available from one of the most reputable names in market research.

💰 Bonus: Pocket a KashKick reward when you sign up for Nielsen Desktop through KashKick and keep it installed for 14+ days. Offers are subject to change and may vary.

Key features:

Earn Automatic Cashback With Rakuten

Rakuten is a cashback app that earns you money on purchases you were already making—which means it can generate cashback while you’re asleep, as long as you’ve shopped through the app or extension beforehand.

Link your credit or debit card to Rakuten, shop at participating stores and the cashback deposits into your account automatically. No receipt scanning. No manual redemption. Just earnings that appear when qualifying transactions process.

Rakuten works with 3,500+ retailers and pays out quarterly via PayPal or check once you earn at least $5.01.

💰 Bonus: Want quicker payouts? KashKick also offers cashback. Install the KashBack extension to get a $2 KashKick reward and earn cashback while online shopping, unlock exclusive deals, automatically apply coupons at checkout and more. 

As soon as you earn $10, you can request cash through PayPal or Venmo, and it only takes 1-3 days to process. Offer amounts are subject to change and may vary.

Key features:

• Automatic cashback on in-store and online purchases
• 3,500+ participating retailers
• Quarterly payouts via PayPal or check
• Free browser extension available

Invest Your Spare Change With Acorns

Acorns is a micro-investing app that rounds up your everyday purchases and invests the spare change. Spend $4.75 on coffee? 25 cents goes into your Acorns portfolio. Those tiny amounts compound over time—growing while you sleep.

You set your risk tolerance and investment goals once during signup. After that, Acorns handles everything automatically. There’s no active trading required.

Plans start at $3/month, so it works best for people who spend consistently enough to make the round-ups worth it.

💰 Bonus: When you sign up for Acorns through KashKick and complete the outlined steps, you get a KashKick reward. You’ll be amazed how much you can stack up in that short period of time! Offer amounts are subject to change and may vary.

Key features:

• Automatic spare change investing with every purchase
• Expert-built, diversified portfolios
• Plans start at $3/month
• Available on iOS and Android

Best for: Beginners who want to start investing without thinking about it.

Note: Investing always carries some risk, and returns aren’t guaranteed.

Park Your Cash in a High-Yield Savings Account

This one isn’t flashy, but it’s the most genuinely passive option on this list. A high-yield savings account (HYSA) earns you interest around the clock—literally while you sleep.

Apps like Marcus by Goldman Sachs, Ally or SoFi make it easy to open an HYSA from your phone in minutes. Current rates hover around 4-5% APY, meaning $1,000 sitting in your account earns roughly $40-$50 a year with zero effort.

It’s not life-changing money, but it’s genuinely passive and risk-free compared to investing.

Learn more about the best places to save money.

Key features:

• Earn interest 24/7 with no active effort
• FDIC-insured (up to $250,000)
• Current rates around 4-5% APY
• Easy to open and manage from your phone

Best for: Anyone with savings sitting in a low-interest account. This is the easiest, lowest-risk passive income available.

Earn Automatic Cashback on Gas With Upside

Upside pays you cashback on gas, groceries and restaurants. Once you’ve claimed an offer and paid, the cashback posts to your Upside account automatically—no additional steps. Upside isn’t a huge earner, but for people who drive regularly, it adds up to $100-$200 a year in cashback.

💰 Bonus: Sign up for Upside through KashKick and get a KashKick reward. Talk about earnings on earnings! Offers are subject to change and may vary.

Key features:

• Cashback on gas, groceries and restaurants
• Cash out via PayPal, direct deposit or gift cards

Rent Out What You’re Not Using

A few rental apps let you earn money from assets sitting idle—and once you list, the bookings and payments are handled automatically.

• Neighbor: Rent out unused garage space, a driveway or storage space. Neighbor handles payments and provides host protection. Once your space is listed and you’ve accepted a renter, the monthly income deposits automatically.
• Turo: If you own a car you don’t use every day, Turo lets you rent it out when it’s sitting in the driveway. Renters can pick up and return your car with minimal involvement from you (especially with Turo’s remote unlock feature).

These take more setup than other apps on this list, but once running, they generate recurring income with minimal active management.

Key features (Neighbor):

• Rent unused storage space or parking
• Automated monthly payments
• Host protection included

Key features (Turo):

• Rent your car when you’re not using it
• Flexible scheduling—block dates you need your car
• Insurance coverage included during rentals

Best for: Homeowners with extra storage or parking space, and car owners in urban areas who can go without their vehicle a few days a week.

How to Spot a Passive Income Scam

“Make money while you sleep” is one of the most-abused phrases in the scam world. Legitimate apps exist, but so do a lot of fakes designed to exploit that same search.

A few red flags to watch for before downloading anything:

• Upfront fees to join or earn. Legitimate passive income apps are free. If an app asks you to pay to unlock earnings, that’s a scam.
• Guaranteed income amounts. No app can promise you’ll earn $500/month passively. Apps that do are overpromising at best, fraudulent at worst.
• Requests for sensitive financial information. Passive apps don’t need your Social Security number, bank login credentials or wallet access. Cash out destinations (PayPal, bank transfer) are the only financial info you should ever provide.
• No verifiable reviews. Before installing any earning app, check Trustpilot, the App Store and Google Play. If reviews are sparse, suspiciously perfect or only recent, proceed with caution.

Every app in this article has a verifiable track record. When you venture beyond this list, a little skepticism goes a long way. For a deeper dive on how to protect yourself, check out KashKick’s guide to avoiding financial scams.

How to Actually Build Passive Income With Apps

Here’s the honest truth: Most people who earn meaningful passive income from apps use more than one. A smart combination looks something like this:

• Set-and-forget layer: Honeygain + Nielsen running silently in the background
• Cashback layer: Rakuten for online shopping + Upside for gas
• Growth layer: Acorns or a high-yield savings account building over time
• Referral layer: KashKick’s referral program compounding as your network grows

None of these individually will change your financial life. But stacked together—and left to run—they build a quiet background income that accumulates while you’re doing everything else.

Apps That Make Money While You Sleep: The Bottom Line

The best apps that make money while you sleep are honest about what they actually do: create small, consistent income streams that require minimal daily attention after setup.

If you’re starting from zero, the fastest first step is KashKick. Share your referral link with a few friends and every time they earn, so do you—without any additional effort. From there, layer in bandwidth-sharing apps, automatic cashback and investing apps to build a stack of passive income that quietly grows.
