How to Use TheOneSpy on Android?

You can deploy many of the features above to spy on Android phones without any complex technical requirements. The app works on non-jailbroken Android phones, though jailbreaking enables many other features of the app.

Here’re the simple steps involved in deploying the TheOneSpy app to monitor an Android phone:

Step 1: Register an Account and Pick a Suitable Package.

Head over to TheOneSpy’s official website and sign up for your account, and then choose a suitable subscription package. After completing the transaction, you’ll be sent a confirmation email with all the details of the transaction, your user credentials, as well as the installation steps.

Step 2: Install TheOneSpy on the Target Android Phone.

This step requires you to handle the target phone physically, but for no more than just a few minutes. 

  • Open a browser on the target phone (preferably Chrome, Firefox, or Opera), and then copy/paste the installation URL you were given in your confirmation email. 
  • When you open this link, it‘ll automatically initiate the download of the TOS download.apk file. 
  • Run the downloaded file and then enter the unique “activation key” in your confirmation email. 
  • That’s it. The app will then disappear into the phone’s background and begin sending out copies of the phone’s data to your user dashboard.

How to Use TheOneSpy on iPhone?

You can also deploy many of the key features of the TheOneSpy app on an iPhone without jailbreaking the phone. It’s even easier to use TheOneSpy on iPhone compared to Androids because you’ll probably not need physical access to the target phone – except if you need to get their iCloud credentials or disable two-factor authentication. You can monitor your target’s phone activities by merely gaining access to the phone data synced to their iCloud account. For this, you need their iCloud credentials, and you also need to ensure that two-factor authentication doesn’t prevent you from logging into the user’s iCloud account without raising suspicion.

Hence, if you wish to monitor an iPhone using TheOneSpy, follow the steps below.

Step 1: Download and Install TheOneSpy on Your Phone.

As with deploying TheOneSpy on Android, you need to sign up for an account and purchase a subscription package on the app’s official website. You’ll then be able to set up the app on your phone with the instructions in your confirmation email.

Step 2: Enter the Target Phone’s iCloud Credentials.

When you run the app, you’ll find a “Sync iCloud” button on the home page, which will take you to a page where you can key in your target’s iCloud credentials. As stated earlier, you need to ensure that iCloud syncing is enabled on the target phone and two-factor authentication disabled.

Step 3: Start Monitoring Your Target iPhone

Once you enter the target’s correct iCloud credentials, you can sit back and begin monitoring your target’s phone activities conveniently anywhere, anytime.

The Neat, Crisp Dashboard of TheOneSpy

How to Use TheOneSpy

All the phone data you need from a target phone are available on your user dashboard. The dashboard is neat, crisp, and highly intuitive, allowing you easily find any particular data point whenever you need to. Each phone data category is clearing labeled to allow you to identify and access any particular data point quickly.

Is TheOneSpy Undetectable?

Your target will never suspect that there is a spy app lurking under the hood of their phone, constantly siphoning every data their phone generates. The app’s inconspicuous operations do not generate graphics or any form of data that might be picked up by the target phone’s display – app icons on the home page, app menu, or app manager in the phone’s settings. Neither does it use up any significant amount of phone data – from battery charge to processing power, memory, and data.


TheOneSpy is a top-notch spy app that’s right at your fingertips. It is designed to help anyone carry out ethical spying campaigns regardless of their technical expertise. You can set up the app and start monitoring your target without ever breaking a sweat or raising the slightest suspicion.
