1) mSpy

mSpy is a powerful affair detect app designed to give users insight into a loved one’s phone activity. I tested its features, and the real-time tracking impressed me the most. The tool made it easy to view deleted messages, access call logs, and even check location history without detection.

I used it on my family member’s phone to test it and was amazed by how powerful mSpy is. It helped me access their phone details with regular updates and ran discreetly without ever notifying the owner.

Features:

• Call Logs and SMS: I was able to view all the incoming calls and outgoing calls with timestamps. You can also check the messages sent and received on your partner’s device, including iMessages with timestamps.
• Social Media: It shows the chats, media, and links shared on social media, along with private chats. I could track Facebook, Instagram, and Snapchat. You can also monitor other chat apps such as email, WhatsApp, Viber, Tinder, Kik, Discord, and many more.
• Location Tracking: You can easily track where your spouse is going and even where they have been. mSpy tracks the phone’s GPS and lets me follow the device in real time, along with a detailed route history.
• Multi-Media Access: If anyone is sharing inappropriate pictures or videos with your partner, mSpy will help you uncover it. It lets you access your target’s phone gallery and view all videos and images.
• Alerts: I received instant updates with its keyword alerts and geo-fencing features. The keyword alert updated me when any restricted words were used or received. Geo-fencing showed me their departure and arrival at a restaurant in Kyoto and sent alerts if they entered any of the restricted areas I had set.
• Other features: You can view their calendar, record the screen, check all the installed apps, view what’s being typed with keylogger, and much more.

2) Spynger

Spynger is one of the best cheating tracker apps, and it will help you gather proof against the sagi-shi that you are targeting. It can help you read messages from all the social apps and dating sites that they use.

My friend suspected her spouse since he was taking business trips to Shibuya and Tokyo more than usual. Hence, we decided to use Spynger to find out what was actually going on. It showed us all the chats and calls; hence, good news, he just had a lot of real business deals at his hand, which he was asked to handle by his company.

Features:

• Chat App Monitoring: Spynger monitors 16+ messaging apps like WhatsApp, Viber, and Tinder. I could view full conversations, including stickers, emojis, and shared locations, which really helped me uncover hidden interactions. While using this feature one thing I noticed was how quickly it updates new chat activity without needing to manually refresh the dashboard.
• Media: I was able to access all images shared via SMS and chat apps, including those deleted later. This gave me a clear picture of any intimate exchanges. The tool lets you filter media by app and date, which makes combing through data faster and more focused.
• Deleted Messages: Spynger lets you retrieve messages that were deleted, which is crucial in cheating cases. I saw conversations vanish on the device, but they still appeared in the dashboard. That really helped me uncover attempts to hide the truth.
• Keystroke: An interesting feature that helped me find out what was being typed on my target’s device. It is powerful enough to display even the password that is being entered for different apps and the device itself.
• Timestamps: The call log details are specific and precise. I saw exactly when calls were made or received and how long they lasted. This feature added more credibility to my findings and exposed timeline inconsistencies.
• Internet History Log: It tracks all browsing activity, including incognito searches, which most other tools miss. I used this to identify repeated visits to dating sites and hidden forums. I recommend checking the history in intervals to spot new trends before they’re deleted.

Pricing:

Here are the plans offered by Spynger:

Annually	Quarterly	Monthly
$9.28	$25.99	$44.56

Free Trial: 30-day refund

3) Spokeo

Spokeo is a people lookup tool that can be pretty helpful in investigating a cheater. It can look up phone numbers, email addresses, full names, usernames, etc. When I tested it, I realized that it is an anonymous lookup tool, which makes it almost a foolproof plan for investigation.

It has billions of records yet scans the database in just a few seconds. You will also find a name directory from A to Z where you can perform a direct reverse search by just clicking on the names. Additionally, I liked its responsive customer support, who answered all my queries on the phone.

Features:

• Phone Lookup: This one time, my friend asked me to look up a number from her fiance’s phone. The number was saved under the name Elle; hence, we decided to use Spokeo to look up the contact information. It turns out that the number belonged to a certain Elle Pupa, a wedding planner company in Kyoto.
• Social Networks: Spokeo can scan 120+ social networks, including dating apps, music sites, gaming platforms, e-commerce apps, and more. I once conducted a username lookup on my online connection years back and rescued myself since Spokeo found him on other dating apps as well.
• Background Check: This tool can provide complete details on individuals, including their aliases, occupations, criminal records, etc, with any of its search input. I was also able to find their residential addresses, which included all past locations along with the current ones.
• Report Alerts: One thing about Spokeo that really stood out among other reverse lookup sites is its alerts. It notifies you when a new piece of information is added or updated in an existing report you have saved.
• Further Details: It also has other details that can help you gather clues and proof for your investigation. For example, I could find details about their neighbors and relatives, online comments, forgotten images, marital status, properties owned, lifestyle data, and much more.

Pricing:

Here are the pricing details of Spokeo:

4) ClevGuard

ClevGuard offers complete tracking for iOS, Android, Mac, and Windows. Hence, no matter the device your target is using to hide their cheating, you will have access to it. Therefore, I could find out about every conversation, every chat, and location traveled.

You might be dealing with a skilled cheater who is difficult to catch, and without solid proof, you’re left in the dark. Fortunately, ClevGuard can help you monitor all apps, track their Wi-Fi connections, and uncover the hidden details you need.

Features:

• Messages and Calls: I could view every message and call, including timestamps, contact names, and shared media. It gave me full insight into who the person was interacting with. While using this feature one thing I noticed was that deleted messages still showed up, which can be very revealing in suspicious situations.
• Phone Location: You can track live GPS and browse through historical location data. It even picks up Wi-Fi locations, which adds another layer of accuracy. I suggest enabling Wi-Fi tracking for better context when GPS is spotty, especially indoors or in multi-floor buildings.
• Camera and Audio Access: I remotely activated the camera and microphone to gather discreet audio-visual clues. It helped me validate whether the user was actually where they claimed to be. The recordings were clear enough for me to make out conversations in a public space.
• Geo-Fencing Alerts: This feature alerted me when the phone entered areas I marked as suspicious. I tested it with two zones, and alerts were immediate. It’s ideal for confirming late-night detours or unusual daily patterns.
• Keyword Tracker: I was able to set keywords like “hotel,” “secret,” or names of concern. The alerts were instant and made it easy to scan for red flags. There is also an option that lets you create category-based alerts, which I recommend for spotting emotional or intimate language.
• Social Media: I tested ClevGuard on my spouse since he seemed to have been using his phone quite often throughout the day. Therefore, I went through his Instagram, Snapchat, Facebook, Telegram, Kik, etc., but it turns out he is just addicted to the “Dragon Quest Walk” game.

Pricing:

Here is the plan of KidsGuardPro by ClevGuard:

Lite Plan	Premium Plan	Family Plan
$39.99	$49.99	$245.99

5) SpyX

SpyX is a phone monitoring solution that comes with 40+ features, enough to shake the world of a cheater. All I had to do was add the device to my account on the dashboard and start monitoring. It lets you read text messages, view call logs, contacts, voicemail, and more. I experimented with it on my kid’s device and liked how transparent it was with what was going on in their phone. It even showed me their battery life, Wi-Fi, and phone data.

Features:

• Chat Apps: SpyX lets me access not just SMSes, but also private chats across Snapchat, WhatsApp, Instagram, Tinder, Telegram, and others. Messages are displayed with timestamps and sender info for clarity. While testing this feature, one thing I noticed was that deleted messages were still visible under the log history, which can be a game-changer when investigating suspicious behavior.
• Screentime: SpyX gave me an app-wise breakdown of screen time across chat apps, social platforms, and browsers. This helped me identify which app someone was using the most throughout the day. I suggest enabling daily alerts to spot any sudden spike in usage—especially late at night, which could signal hidden conversations.
• Social Media Surveillance: I used SpyX to track someone’s Instagram and Facebook DMs, comments, and likes in real time. It revealed a full picture of digital behavior across platforms like WhatsApp and Snapchat. From my experience investigating a flagged account, this feature offered nuanced patterns that weren’t obvious from just chat logs alone.
• Internet Usage: If you want to find out where your cheating partner has been using their data or Wi-Fi the most, SpyX will show you that as well. Moreover, during this research period, I could also view browser bookmarks, browser history, and emails.
• Remote Control: I was able to record my kid’s screen, capture screenshots, get camera access, get audio access for recording, etc. In fact, I was also able to record the surrounding sound, which will help you find out if your partner is actually working late or is getting lit in a club.
• Locations: It offers both GPS tracking and geo-fencing. SpyX’s tracking shows the date, time, and routes on a map clearly with a detailed address. Setting up a geo-fence was also quite easy since I could get instant alerts of my kid’s arrival and departure from chūgakkō.

Pricing:

Here are the pricing plans offered by SpyX:

12 Months	3 Months	1 Month
$11.66	$28.32	$49.98

6) Social Catfish

Social Catfish is a people lookup service that helps you keep scammers at bay. It is basically helpful for people who are interested in online dating and want to find out if their potential online date or current Tinder connection is trustworthy.

It can also help people in a relationship find out about the other individuals your partner chats with on social media. This tool helped me find out who a phone number or an email address belongs to. Additionally, you can look up a person using their image.

Features:

• Database: Social Catfish has 200 billion records in its database. It gathers its information from public records, social media, court records, blogs, websites, etc. However, I found a few reports with missing or outdated data.
• Username Lookup: Eager to find out who that one username is who keeps liking and commenting on your girlfriend’s post? Social Catfish can instantly find out their real name, age, address, email ID, etc.
• Phone Number Lookup: I was troubled for over a week by the thought of a number that would keep calling my spouse after work. Hence, I gave Social Catfish a try and laughed when I found out it was our new plumber’s number who has been working with us for our renovations– he just must have forgotten to share his new contact with me.
• Anonymous: This lookup site is entirely anonymous; therefore, the target never finds out that you were checking their details. I tried it during a case review and confirmed there were no alerts sent. You will notice the dashboard doesn’t require login just to perform basic searches, which adds a layer of stealth..
• Report: Apart from name, age, and other obvious details, you will find a vast amount of data such as criminal background, actual occupation, relatives, etc. I could also find their educational background, properties owned, bankruptcy, images, and much more.

Pricing:

Here are some of the plans offered by Social Catfish:

Basic	Premium
$27.48/ Month	$39.95/ Month

Free Trial: 3-Day Paid Trial for $5.73

Issues of Cheating Investigation Apps and Ways to Mitigate Them

No cheating investigation app is 100% accurate all the time since, apart from its database, it also depends on external factors such as your input. There are also other challenges, such as legal and privacy concerns, etc.

Therefore, here is a table that shows the issues related to cheating investigation apps and how you can mitigate them:

Limitation	Resolution
False positives/ inaccuracies	• Use multiple tools • Cross-reference with other search methods • For image search, use front-facing high-quality images without too many accessories
Limited data	• Find out where the tool gathers its data from • Use a tool that updates its database consistently
Device and platform incompatibility	• Research before committing to find out supported devices and platforms
Potential data manipulation	• Make sure it’s a legit site that shows complete data -Do not stop at the basic search when it shows half details since some apps display a few fake shock-value results for you to open the full report
Emotional and mental distress	• Continuously using such apps can lead to a lot of distress and anxiety • Confront your partner directly to get the truth
Legal and ethical concerns	• Read the tool’s terms and conditions, plus privacy policies carefully
Privacy concerns	• Do not misuse the data gathered • Do not spy on them with malicious intent • Try to get consent and do not cross unnecessary lines like rooting or jailbreaking
Expensive premium features	• Opt for tools that offer one-time report • Some tools have a moneyback guarantee

Verdict

Now that you are familiar with some of the top cheating investigation apps, you must know that they have their own strengths and weaknesses. Based on my research, I would like to recommend the following:

• mSpy: A reliable and comprehensive solution offering real-time tracking, social media insight, and keyword-based alerts in a secure, discreet package.
• Spynger: This app delivers remarkable access to deleted messages, timestamps, and passwords with a robust keystroke logger that runs silently in the background.
• Spokeo: A cost-effective and powerful reverse lookup tool that scans social media, names, emails, and phone numbers with impressive accuracy and alerts.
