Private investigator reveals unexpected app your partner might be using to cheat on you

A private investigator has revealed the unexpected app your partner could be using if they're being unfaithful.

We've all heard about people checking their partner's phone and discovering suspicious messages, phone calls, and dating apps. Even bank accounts can sometimes reveal some questionable activity.

Despite the usual culprits, there's apparently one app that might seem very innocent, but it could be hiding secrets.

Aaron Bond is a private investigator from Bond Rees. He explains that although messages and call logs can unmask a cheater, there are more subtle ways to catch them out - such as supermarket loyalty cards.

“While most people think of text messaging and call logs as the obvious signs of cheating, there are often other signs that can uncover and paint a larger picture,” Bond told the Mirror.

“Data is limited, but it does tell you a date and location, which is easily accessible if you log into your account.

“If your partner claims they were working or out with friends but the account shows they made a purchase in a completely different area, then it’s a clear red flag.”

The location isn't the only clue either, with Aaron explaining that the 'favourites' section of loyalty cards could give away some answers, too.

For example, if your parter has bought champagne and a romantic dinner for two - but you never got a sniff of it - that could be a red flag.

"Why would an app recommend products that you have never purchased, the simple answer is it wouldn't," Aaron added.

"These apps use your past buying signals to make you want to spend more with them, so if unusual items are being recommended to you or your partner, chances are they have purchased them in the past, just not for you.

"Technology doesn't lie, it's just data and when that data paints a different picture to what you are being told, that's when the alarm bells should start to ring."

A private investigator in Australia also echoed the same sentiment, revealing that one of her clients had discovered her husband was cheating in the same way.

Cassie - who goes by @venusinvestigations - explained: "They lived in Queensland and he was going on these trips to see his family in New South Wales pretty regularly which he never used to do."

Cassie she suggested her client look into rewards accounts, which she did, discovering her husband had been making a lot of transactions in Queensland, which wasn't where they were living at the time.

The suburb did happen to be where the husband's ex-girlfriend lived, however.

"Bro gave it up for a few extra reward points," she said, adding: “$10 off your shop but a very expensive divorce.”
