Yes. If they’re using an iOS device, you can install a spy app without laying a finger on their phone or tablet. All you need are the right iCloud credentials. If your partner uses an Android phone, the process is slightly different. You'll need to get your hands on their device to install the app, but it is not as difficult as it sounds. Once installed, an Android spy app will send collected data to your web-based control panel, so there is no need to touch their phone again.
