How to Catch a Cheater Online

Here, you’ll find out what’s happening behind their screens. Dive into my guide on how to catch a cheating partner for expert tips and tools to uncover the truth.

How many people have caught their cheating partners red-handed? Do you know anyone’s stories?

Me neither.

I’ve watched the movies with all those dramatic scenes. A deceived spouse breaks into the house at the right moment and screams, “How could you?!” Bad guys panic. The truth wins.

Cool trick, but it’s hard to replicate it in real life.

Why? For one, сheaters are not so stupid. And you, me, and all the people reading this have a lot of work to do. We’ve got no time to sit in our cars with FBI glasses on, waiting until their affair partner shows up at the door.

Honestly, if we were the FBI agents who spy on their suspects instead of doing an online investigation first, we would be fired. Catching a cheater is no different from this. 

When people use the Internet, they leave behind a digital trail of information. If your partner is not a fan of old-school flip-phones, they 100% leave it too. So your task is simple: follow their trail.

Take my guide as your checklist with detailed instructions on how to catch a cheating partner online. We’ll go over the top 10 ways to collect the hard evidence of their indiscretions and explore some helpful tools along the way.

Way 1. Monitor Your Partner’s Phone

If I had to suggest just one way to catch a cheater on Instagram or any other online platform, it’d be to monitor their phone. This little gadget can give plenty of data pieces to put together the puzzle of your partner’s secret life. I’m talking about call logs, text messages, media files, transaction history, and location data.

Let’s look at how you can do this.

Free Ways

It takes little effort to find out if your partner has an active dating profile or flirts with someone on Facebook. 

Simply take their phone, check the right spots, and you’re done.

You might feel confused now because you don’t need a guide to find cheating husband online by going through their phone. And what are these “right spots” I’m talking about? This sounds a bit vague but bear with me for a second.

Here’s the secret no one tells you: your partner’s phone can show you the most used apps. These are the places where cheating evidence is most likely to be found, so you don’t need to check every single app on their device.

On iPhones, you can find usage statistics in the Settings app under “Screen Time.” On Android devices, go to Settings > Digital Wellbeing & Parental Controls. Once you’ve done this, open the app they use most often, such as a browser or Instagram, and check what’s happening there.

If you haven’t found anything in their chat history or browsing logs, please don’t assume I gave you a bad tip just yet. Your partner might be extra careful about covering their tracks. The article below has more info about deleted cheating evidence.

Spy Apps – Best Way to Monitor Your Partner’s Phone

Collecting evidence is not as hard as interpreting it right. Your brain might fill in the blanks and lead you to the wrong conclusion, especially if parts of the conversation are missing.

Spynger, the advanced spy app, does exactly just that. It lets you see what your husband is doing on his phone in real time. This tool sends data from the target (your husband’s) device to your online dashboard, accessible from any PC, tablet, or smartphone.

Way 2. Track Your Partner’s Location

Unsure how to catch my husband cheating online? How about we first figure out where he is offline? The fact he lies about his whereabouts might be an eye-opener for you.


GPS tracking is simpler than you might think. You don’t need to put a bug on your husband’s car to track his movements. Detectico, an online tool, accurately determines the current location of a cell phone by its number. Make it work by following these steps:

  1. Go to and create your account in less than 1 minute.
  2. Enter your husband’s phone number into the search panel.
  3. Detectico will send an anonymous message to find your husband’s phone. You’ll see his location on the map in your dashboard. 
  4. Now you can find cheating husband online whenever you want!

What I especially like about Detectico is that it’s extremely accurate. Unlike similar apps, it pinpoints location down to 4 meters and shows the address as well. With Detectico, you’ll know so many details about your husband’s whereabouts that he won’t be able to keep his lies straight.

Way 3. Monitoring Your Partner’s Online Activity

Your husband’s web browser can give away a lot of information about him. Here’s how to find out if your spouse is cheating online for free using this trick:

  1. When he’s not around, open a browser on his PC or tablet.
  2. Go to Settings and choose History. Here, you’ll see websites he frequently visits. 
  3. If his browsing history is clean, then he might have erased it. That’s a big red flag, but don’t draw conclusions just yet. We have a few more places to check.
  4. Go back to Settings and click on Autofill. This is where the browser saves information like usernames and passwords for websites. 
  5. Even though you won’t be able to copy his passwords without knowing them, you can still see the platforms on which he has accounts. This will help you find cheating husband online.

Haven’t found anything? I get why you want to slam this laptop shut and give up, but don’t do this. There’s still one more thing you can do. Enable autofill and cookies on his device and wait for a couple of days. Then, go back to Settings and check for updates.

Way 4. Pay Attention to Your Husband’s Behavior

I know, I know that you’ve seen tons of posts about signs of cheating, but this tip is different. Instead of focusing on typical red flags, such as mood swings and unusual sex drive, let’s talk about tech signs of cheating. 

Knowing these key signs can help you figure out how to find cheating spouse online and whether his behavior screams cheater or not.

  • He has changed passwords on his personal computer, phone, and tablet out of the blue.
  • Whenever you walk in, he quickly puts his phone face down and shuts the laptop.
  • He never forgets to lock his devices when you’re around. And if he forgets, a mini panic attack hits him.
  • He walks out of the room to read or type a message on his phone.
  • He has his ex girlfriends phone number saved under a fake name. His contact book is full of such fake contacts.
  • He’s glued to the screen for hours and gets defensive when you ask what he’s doing.

If you’ve ticked off several of these signs, he’s definitely up to no good. Let’s find cheating husband online together by following his financial trail. His spending habits can reveal the darkest secrets.

Way 5. Look for Unusual Activity in Their Credit Card or Bank Statements

Swift bank transfers let online dates shower each other with gifts before they meet in person. Actually, that’s a sweet move.  But when married men spend their income on a would-be mistress, it’s… just disgusting. 

Unusual activity on your partner’s credit card is a dead giveaway that he’s cheating on you. Bouquets of flowers he never buys you? Check. Victoria’s Secret receipts? Check. If you notice any expenses related to gifts he didn’t get for YOU, it’s time to ask some hard questions.

If you have enough time to go through his transaction history, here’s how to catch a cheater for free online: view the details of each transaction. You might spot the web addresses of online stores or even dating platforms if he has replenished his accounts to send virtual gifts.

Way 6. Check Their Social Media Accounts for Any Suspicious Activity.

If you don’t feel like it’s the right moment to track spouse iPhone, take a step back and focus on the info you can access now. I’m talking about his online accounts. So, how to find cheating spouse on social media?

Whatever platform he has a profile on, consider taking a look at:

  • Likes. People who always like his pics or posts are definitely the ones he talks to often. 
  • Posts and stories. If he suddenly starts sharing content with double meaning, it may be a message to someone specific.
  • Friends. If your partner has recently become close to new people (or one person in particular), you might want to find out more about them.

Way 7. Use Keyloggers to Track Their Keystrokes.

If your family uses a shared computer or laptop, you can find cheating husband online by installing a keylogger on your device. This software records keystrokes made on the PC, so it’s easy to find out what emails and passwords your husband is using. You’ll be able to log into his email, social media, online store accounts, you name it. 

Just a word of caution: some malware disguises itself as a free keylogger. So, weigh your options carefully before installing anything on your PC.

Way 8. Use a Background Check Service to See If They Have a Cheating History

You know how they say, “Once a cheater, always a cheater”? It’s kind of a cliché, but if your partner has a history of cheating, those old habits could creep into a new relationship. I’m not here to scare you, just to offer a tip on how to find a cheating spouse online: use a professional background check service. These people can find a ton of info about his past and current online activities.

Way 9. Install a Hidden Camera in the House

I didn’t mention hidden voice recorders in this post for a reason. In most jurisdictions, it’s illegal to record someone’s conversations without their consent. However, placing a nanny cam in the common area of your house, such as the kitchen, dining room, or living room, is legal. You’ll see if he texts or calls someone else behind your back.

Keep in mind that this method might not be 100% risk-free if your local laws prohibit this type of activity. For example, some states say no to cameras with sound recording. So, it’s better to look into this before taking any steps.

Way 10. Get Help From a Detective Agency

Hiring a private investigator is a good option, but it is not a cheap one. Detective agencies usually charge hourly fees of $100 to $200. Why is the price tag so heavy? Licensed private investigators know how to collect admissible evidence, which you can legally use in court. 

If you just want to know how find a cheating spouse online without taking any further steps, consider trying other methods first. They’re no less effective than hiring a private investigator.

Is using a spy app the best way to catch cheater online?

Yes, but not all spy apps will do what you expect them to do. Most free solutions have a limited number of features, e.g., they may not offer social media monitoring or location tracking. It’s better to choose a middle-ground option. In other words, look for an affordable app that comes with a rich set and gets good user reviews. A few spy apps that check these boxes are Spynger, mSpy, and Eyezy.

How do you catch a virtual cheater?

Cheating is cheating, no matter where or how it happens. If you suspect your partner is texting someone else, use a spy app to find cheating husband online. The hidden social monitoring tool will send you immediate updates on their new texts, posts, friends, and, most importantly, real-time location.

How to secretly catch a cheater?

It’s ok to be afraid of face-to-face confrontation, especially if your partner has a history of being defensive or manipulative. Your best bet in such a situation is to gather solid evidence by using a spy app. It runs invisibly in the background of your partner’s device, sending their data to your online account.
