A friend of mine recently started suspecting that her boyfriend might be using dating sites again. She noticed him being more secretive with his phone lately. Now she’s wondering if there’s any way to check whether someone has a profile on dating platforms.
@Ryan I understand why she’s worried. I had a similar situation once and I used a lookup tool I tried to check publicly available info. It helped me in two ways: a reverse phone lookup showed whether the number pops up with dating profiles, and a reverse image search helped see if the same photos show up on dating sites or other profiles. It didn’t prove anything definite, but it gave me public clues. If you want to explore, this tool is what I used.
@Ryan If you can guess his usual username (like a social media handle), you could use Detectico’s reverse username lookup to scan public web sources for matching profiles. It sometimes picks up dating-site accounts tied to that username. I once tried it on my own handle and discovered an old forum profile I’d forgotten about. It’s not foolproof, but it can give you some clues if she suspects he’s active online. Hope that helps!
@Ryan I’ve used Scannero for something similar. For checking if a username shows up on dating sites, the Username lookup is the fit here: you can search a username across public sources to see where it appears online. If the same handle is used on dating platforms, you might spot it. I’ve also used the Reverse phone lookup a few times to see who a number might be tied to in public records. Quick heads up: location results only appear after the recipient opens the tracking link, not just from a lookup.
@alex_turner92 I get the appeal of username scans like Detectico’s, but I’m pretty skeptical. I once tried a “free” lookup and ended up sharing my email and phone, which triggered a flood of spam and dodgy tracker scripts. Services promising a quick scan often hide trackers or phish for personal info—classic scam tactic. I’d be careful clicking those banners. Better to stick to public web searches or reputable OSINT tools than sign up for anything that sounds too good to be true.
@Ryan That’s tough for your friend. I went through something similar last year when I noticed my ex was being weird with his phone. I actually used Scannero to check his usual gaming username - turns out the same handle popped up on a couple dating sites. Their username lookup searches across public sources to see where usernames appear online. Of course, it only shows publicly available info, but it gave me the clarity I needed. Hope your friend finds the answers she’s looking for!
@skyline_rider wait, so does it mean those tools that everyone mentioned could be scams? 
I’m confused - are they actually dangerous to use?
My cousin tried something like that once to check on her ex, but she said it just asked for payment and didn’t really show anything useful. Is that what you mean by “too good to be true”?
How can we tell which ones are legit vs sketchy? 
I always get nervous about putting my info into random sites…
@Ryan I ran into a similar issue when I tried to see if an old ex was still lurking on a dating app. I used Detectico’s reverse username lookup to scan a handle she’d used across public sources—it actually turned up a profile on one site that matched. It doesn’t guarantee a match 100%, but it gave me somewhere to start. If you know his phone number, you can also test the reverse phone lookup for any linked profiles. Worth giving it a try!

@Ryan Tell your friend to just ask him directly. If she can’t trust him enough to have that conversation, the relationship’s already broken. Snooping around with sketchy lookup tools won’t fix trust issues. Either she talks to him or she walks away. Playing detective is just delaying the inevitable.
@Ryan Look, I’ve seen this play out a dozen times. Tools that claim to reveal dating-site profiles usually don’t work as magically as ads promise, and they can drag you into scams. If anything, rely on practical checks: talk openly with the partner, watch for real changes over time, and if you investigate, stick to publicly available info only and avoid handing over money. Old lesson: privacy isn’t a puzzle you can shortcut with a click.
@Ryan CSI: Love Life edition, huh? There isn’t a universal dial to see if someone’s on dating sites, and many tools can be sketchy. If you still want to look, stick to public signals: reverse image search for their photos, and reverse username lookups across sites you think they might use. Quick reminder: privacy matters, a real talk with your friend might be the best route.
@Ryan, I’m really sorry you’re both going through this uncertainty. I know how unsettling it feels when someone you trust starts guarding their phone. A while ago, I noticed my partner hiding notifications and it filled me with doubt. What helped was sitting down for an honest chat about boundaries and feelings, without accusing. Sometimes these conversations open doors to understanding rather than resorting to sneaky checks. Your friend isn’t alone in this—open communication and patience can ease that knot in the stomach more than any tool.
@wanderer_jk raises an important question about these lookup tools. On one hand, services like Detectico and Scannero can provide legitimate public information searches - several users here have reported finding actual profiles using username lookups. On the other hand, as @skyline_rider warns, many similar services are indeed data harvesting operations that collect personal info and deliver minimal results.
I once tried a “free” lookup tool myself and ended up getting bombarded with marketing emails for months. The key seems to be researching reviews beforehand and never providing more personal data than absolutely necessary. Some tools work, but the landscape is definitely filled with sketchy operators looking to exploit people’s emotional vulnerability.
@Ryan Oh man, I can totally relate. A while back I got swallowed by this same weird paranoia when my partner started being oddly secretive with their phone after a crazy few months at work. I briefly tried to “check” if they had profiles on dating sites, chasing a few vague tricks I’d heard about. It felt like a gnawing knot in my stomach—the more I dug, the foggier everything got. I found nothing definitive, but I ended up more anxious and we barely talked for days. Eventually we sat down and talked honestly, set some boundaries, and I learned that trust isn’t built by sleuthing but by real conversations and time. If she’s worried, a calm talk beats chasing shadows every time.
