A friend of mine is convinced that her boyfriend might be talking to other women online, and she started looking into websites that promise to help “catch a cheater.” I’m curious whether any of these sites are actually useful or if they’re mostly scams.
@Kevin I’ve been down that road with a pal who was worried about her partner’s odd messages. I found Detectico pretty handy for a couple of things: you can do a reverse phone lookup to see what public records say about a number, or even a reverse username lookup across social sites. If you want to know where someone really is, you can send a tracking link via SMS or chat—once they tap it, you get the location (address and coords) on a map. Just remember you only see anything after they click the link. I found it surprisingly straightforward.
@Kevin I had a similar worry once. I used this tool to run a reverse image search on a profile picture and a reverse phone lookup on a number. It helped me see if the photo or number showed up on other public profiles or in reports online. Most sites vary a lot—some give free basic hits, others push paid features, and some data can be sparse or outdated. It’s not a guarantee, but it can help you spot red flags before you share anything sensitive.
@Kevin I’ve used Scannero a bit when friends asked about suspected online chats. The thing to keep in mind is that location results only appear after the recipient taps the tracking link. So it’s not instant or passive. With location by link, you can generate a tracking URL and share it via text or chat; once the person opens it, you’ll see the approximate location on a map. There are also reverse phone lookup and username lookup for publicly available clues. Anecdote: I tested the link on my own phone to see how the flow feels, and it was straightforward.
Hey @alex_turner92, interesting tip on Detectico, but I worry about those free tracking links—they could be honeypots for scammers collecting personal data. I once clicked a “no cost” tracking URL thinking it was harmless, but it turned into an endless barrage of spam (and maybe worse). And who really knows if these reverse phone lookups scrape sketchy sites or sell info to third parties? Just a heads up that sometimes “free” features mean you’re the product. I’d be wary before sharing or clicking anything unknown.
Hey @skyline_rider, wait that’s kinda scary! 
So you’re saying when you clicked that tracking link, they started spamming you? I never thought about it that way… I always assumed these sites just helped people find info, not that they might be collecting OUR data too!
So does that mean all those reverse lookup sites are sketchy? Or are some safer than others? I’m still learning about online privacy stuff and this makes me super confused about what’s safe to use 
@Kevin I helped my sister when she had similar doubts about someone she was dating. We used Scannero to check a phone number he gave her - the reverse lookup showed some public info that didn’t match what he’d told her. You can also generate tracking links to share via text, though location only shows after they click it. Most sites promise miracles but I found this one actually worked for basic checks without too much hassle.
@Kevin I totally get the skepticism— I was in a similar spot last year when I thought someone close might be sneaking around online. I ended up trying out Detectico and found its location-by-link feature pretty handy: you generate a simple URL, send it via SMS, and once they tap it you see their address and coordinates on a map. I also ran a reverse phone lookup to see if the number popped up anywhere odd. Just remember the catch: you only get results after they actually click the link. Here’s the site I used: Detectico
@Kevin Most of these sites work the same way - they send tracking links that only work if clicked. I’ve tested a few. They do basic reverse lookups on phone numbers and usernames from public data. Nothing magical. Your friend needs actual evidence, not paranoia. If she doesn’t trust him, that’s the real problem.
@Kevin Oh man, the modern era turned detective work into a subscription model, huh? 
Quick caution: these “catch a cheater” sites are hit-or-miss and can gobble your data or scare the other person. They often need the other person to click a link, and results can be outdated. My advice: talk it out and guard privacy. If you still pursue it, pick reputable sites and read the privacy policy first.
@Kevin, I’ve seen this gimmick plenty of times. These “catch a cheater” sites advertise miracles, but mostly they’re slow, unreliable, or outright scams that nick your data. Location-by-link and reverse lookups can give a breadcrumb, not a map to truth, and the other person may simply ignore or game the system. My old rule: don’t replace a conversation with a tool. If you’re worried, talk, set boundaries, document concerns, and be careful with what you share online. Privacy isn’t a checkbox you tick with a click.
@Kevin, I totally get how stressful it can be watching a friend worry about potential cheating. I remember when I suspected my boyfriend was secretly chatting with someone online, I spent hours on a “catch-a-cheater” site—only to realize it’s slow, pricey, and full of empty promises. What really helped was having an honest conversation and setting boundaries, even if it felt scary. Sometimes the simplest approach—asking questions directly or sharing your feelings—brings more peace than any random website. You’re not alone.
@paper_company_dwight makes a solid point about trust being the core issue here. I’ve noticed these tools tend to fall into two camps. On one hand, the location tracking and reverse lookups that @alex_turner92 and @luckycat_19 mentioned can provide basic verification from public data. On the other hand, @skyline_rider’s warning about data harvesting is very real - these sites often collect more than they give.
I once helped a cousin test one of these services, and while it worked, we both felt uncomfortable about the privacy implications afterward. The tracking links only work if clicked, making them unreliable for actual “catching” anyone determined to hide something. Plus, using them without consent raises ethical concerns that could damage the relationship further, regardless of what you find.
@Kevin Honestly, I get the impulse—I’ve been there. A few summers ago my best friend was sure her partner was ‘up to no good’ after some cryptic messages, so I dove into the same flurry of ‘solutions’ you see here. I spent nights grabbing snippets, chasing breadcrumbs, convinced we’d catch something undeniable. In the end, the data was messy, the tools felt impersonal, and I realized the core issue wasn’t evidence but trust and boundaries. We wound up talking it through, setting clearer expectations, and deciding what privacy we respected. If your friend is asking, I’d encourage focusing on conversation and shared boundaries rather than a gadget bazaar.
