Phone Spying Apps – Top Options for iOS and Android Devices
1. Peekviewer
Peekviewer is a leading spy app that allows you to explore Instagram accounts and stories without your own Instagram account. This means you can view anyone’s stories, account, or simply browse on Instagram anonymously.
It’s perfect for parents who want to check on their children without making it feel intrusive. Peekviewer is also used by content creators for research purposes, as this tracking app lets them access Instagram profiles that aren’t public. Additionally, business owners also find a lot of value in this app as it lets them anonymously check what their competitors are posting and creating.
We also liked that there is no need to download an app to use Peekviewer. It is designed to work smoothly in your browser. All you need to do is enter the link of the profile you want to access, and you’ll see their content within seconds.
Additionally, if you want to revisit content you’ve already viewed before, Peekviewer lets you do that. It saves all the content you’ve viewed earlier for up to 3 months, even if the original content is no longer available on the profile.
If you’re looking for an effective tracking solution that lets you view likes, stories, or tagged photos of specific people while being discreet, Peekviewer is a solid choice.
Features:
- Anonymous Instagram viewing – Browse profiles, stories, likes, and tagged photos without revealing your identity.
- No account or app required – Access Instagram content directly through your browser without signing up or installing anything.
- Works across all devices – Use Peekviewer smoothly on Windows, Apple, Android, and iOS across phones, laptops, and desktops.
- Private story access – View Instagram stories without triggering view notifications or alerts.
- Saved viewing history – Revisit previously viewed content for up to three months, even if it’s later removed from the profile.
2. Spynger
Spynger is often described as a tool to catch a cheater, but once you look closer, it’s really a full phone monitoring solution that covers far more than just messages.
What we noticed first is how much Spynger can see. It can track text messages, including deleted ones, log keystrokes, and show who someone is calling and when. Location tracking is also part of the setup, with GPS updates and a geofencing feature that alerts you when someone enters or leaves certain places. That could be home, work, or anywhere else you decide to mark.
Spynger puts a lot of focus on social and messaging apps. It works with WhatsApp, Facebook Messenger, Snapchat, Instagram, Telegram, Tinder, Skype, Discord, and several others. Chats, shared photos, and activity inside dating apps are all visible from the dashboard.
The app is designed to stay hidden once installed. There is an invisible mode, along with tools like a hidden screen capturer and keylogger, so the person being monitored does not get alerts or warnings. Spynger works on all smartphones and supports different operating systems, with everything managed from a single control panel.
If you need a tracking app that stays discreet while offering detailed insight, Spynger covers a wide range of monitoring needs without drawing attention to itself.
Features:
- Deleted message tracking – Read text messages even after they’ve been removed from the phone.
- GPS location and geofencing – Spy on iPhone and Android phones to track real-time location and receive alerts when someone enters or leaves marked places.
- Social and dating app monitoring – Access chats, photos, and activity on WhatsApp, Instagram, Snapchat, Tinder, Telegram, and more.
- Hidden keylogger and screen capture – Record typed activity and on-screen actions without triggering alerts.
- Invisible background mode – Monitor the device quietly without the user knowing or receiving warnings.
3. mSpy
mSpy positions itself as a parental control tool, but once you look at what it actually does, it goes much further. It’s designed to give a clear picture of what’s happening on a phone, without interrupting how that phone is being used. The idea is simple. You stay informed, and the device keeps working as normal.
mSpy logs keystrokes and taps, shows who’s been called, what’s been searched for, and lets you review text messages, including ones that have already been deleted. Social media chats are also covered, which is often where most activity happens anyway.
Location tracking is another big part of the app. mSpy shows real-time GPS locations and route history, so you can see where the device has been and not just where it is right now. Updates come in frequently (every 5 minutes), and the information is protected with bank-grade encryption.
mSpy works across devices and operating systems. It supports both Android and iPhone, including options for jailbroken, rooted, or standard devices. The app runs quietly in the background and stays hidden, without affecting performance or alerting the user.
Overall, mSpy suits parents or guardians who want steady access to information rather than constant checking. It’s feature-heavy, but it keeps things organised, which makes ongoing monitoring easier to manage over time.
Features:
- Keystroke and activity logging – Track typed searches, taps, and passwords directly from the target phone.
- Call and message monitoring – View incoming and outgoing calls and read texts, including messages that were deleted.
- Real-time GPS tracking – See current location and full route history that updates every five minutes.
- Social media chat access – Monitor conversations and media posts across popular social platforms.
- Silent background operation – Compatible on Android and iPhone devices, including rooted, jailbroken, and standard setups.
4. uMobix
uMobix is a monitoring software that’s mostly talked about as a parental control tool, but in reality, it works like a full phone tracker that can be used to catch a cheating spouse. It’s also meant for parents who want to know what’s going on without asking questions every day or constantly checking the phone themselves.
The app covers most areas people usually worry about. You can see calls, messages, and activity across a long list of social and messaging apps. That includes WhatsApp, Instagram, Facebook, Snapchat, TikTok, and others. Messages can still be viewed even if they’ve been deleted, which is something many parents specifically look for. Photos and videos stored on the device are also visible, so it’s not limited to just chats.
There’s also a keylogger built in. This records what’s typed on the phone, including searches and passwords. Location tracking works in real time and shows location history as well, so you can see where the device has been during the day and where it is right now. Updates come in every few minutes, which helps you stay informed at all times.
uMobix is a fully functional iOS and Android Monitoring app and runs quietly in the background. For parents who want regular updates instead of occasional checks, it does the job without making things feel overcomplicated.
Features:
- Social and messaging app monitoring – Spy on Android and Apple phones to track chats and activity on WhatsApp, Instagram, and other popular apps.
- Deleted message access – View texts even after the user deletes them from the device.
- Built-in keylogger – Records typed searches, passwords, and on-screen input as it happens.
- Real-time GPS tracking – Monitors current location along with full location history at all times.
- Quick setup and background mode – Installs in about five minutes and runs quietly without alerting the user.
5. Scannero
Scannero is a tracking software, but it doesn’t work like the usual phone trackers that need to be installed on a device. Instead, it’s more about finding information using phone numbers and links, which puts it in a slightly different category. You don’t need physical access to a phone, and that’s really the whole point of it.
The main thing Scannero does is location tracking by phone number. You enter the number you want to locate, and Scannero sends a message with a link to that number. If the person clicks the link, their location is shared with you and shows up inside your account. This usually takes a couple of minutes, depending on how quickly the message is opened.
There are a few other tools built into the platform as well. Scannero offers reverse phone lookup, which helps you figure out who’s behind unknown calls or messages. There’s also a reverse username lookup that can pull up linked online accounts, including social media and dating profiles.
If you’ve lost your phone, Scannero lets you send a custom message to your number, asking whoever finds it to return it. There’s also an email and phone leak checker, which scans databases to see if your details have been involved in a data breach.
Features:
- Phone number location tracking – Send a location request by SMS and receive the phone’s location once the link is opened.
- Request-based tracking system – Locate devices without installing software or needing physical access to the phone.
- Reverse phone lookup – Identify unknown callers and see who’s behind unfamiliar numbers.
- Reverse username search – Find linked online accounts, including social media and dating profiles.
- Privacy and safety tools – Check for email or phone data leaks and send anonymous voice messages when needed.
Best Spy Apps Compared
What Is a Spy App and How Does It Work?
Using a spy app, you can track someone’s phone. The best spy apps on the market let you see the target device’s social media activity, internet history, calls, texts, photographs, and more. Some even allow you to track a phone’s location and alert you if the device enters or leaves a particular location.
Most spy apps must be installed on the phone of the person you want to track. Some apps, however, don’t need installation, and all information is tracked on the cloud. Installation takes less than five minutes and requires you to grant specific permissions on the target’s phone. Once everything is set up, the best apps allow smooth and uninterrupted tracking.
There are several free Android spy apps cheating spouse available for tracking, but they aren’t entirely effective, and there is always a risk of data leaks with free apps. That is why it is important to choose a paid and reliable app for effective tracking.
Why Do People Use Tracker Apps?
Tracker apps have several use cases. They give people peace of mind by helping them keep track of their loved ones. Additionally, they are beneficial for business owners and creators to stay ahead in the game. Below are some of the main reasons people use spying apps:
1. Tracking a cheating spouse
Tracking apps are one of the best methods to spy on Android and iPhone when you suspect that your spouse is cheating on you, but have no way to confirm your suspicions. These apps can track your partner’s phone and see who they call, message, talk to frequently, what messages they send, and their entire social media activity.
2. Parental control
No one is exempt from the dangers of social media. Children are especially vulnerable to social media as there is all sorts of content available on the internet, some of which can be detrimental to their mental health and physical safety. Spy apps for iPhone and Android allow parents to monitor and limit their children’s social media usage by offering several beneficial features.
3. Tracking elderly parents
If you have older parents at home, tracking applications are an excellent way to know where they are when they go out. These apps allow you to track your parents’ phones and give you their location and whereabouts at all times.
4. Businesses and content creators

A Guide to Find the Best Spying Applications
Choosing the right spying application for your needs is crucial. If you want to track your spouse, but you choose an app that only tracks location, that won’t be of much use to you. Or, if you want to track an iPhone but choose an app that only supports Android, you’ll be wasting time and money. Below is a detailed guide on how you can find the best spy app for your specific needs:
Device Support
The first thing to check is if the phone monitoring software supports the OS of the device you want to track. Thankfully, the leading spying applications mentioned in this guide support both iOS and Android versions, so you can start tracking without worrying about compatibility.
Feature Scope
Choose an app that has the features you need. If you only want to track someone’s location, there is no point in paying extra money for other features. You’ll only need a location tracker like Scannero for your purposes. Similarly, if you only need to track someone’s Instagram profile, you’ll be wasting money on extra features like keylogging and GPS tracking.
Stealth Behaviour
Ensure the app you’re choosing offers stealth mode so the tracking app works quietly in the background without letting the user know that they are being tracked. Additionally, the monitoring software should work optimally and not drain the user’s battery.
Check for reviews of the spying app on platforms like Reddit, Quora, and TrustPilot to know how the app performs in terms of battery, space, and overall stealth.
Pricing Model
Pricing is an important factor to consider when choosing a spying application. Free spy apps on the market are unreliable and do not offer advanced tracking tools. The paid ones, on the other hand, protect personal information and offer various price ranges to suit different customers.
The leading apps offer daily, monthly, and weekly pricing to cater to users who need short-term access as well as long-term monitoring.
