I am looking for reliable Android apps for tracking devices. Has anyone used them? Do they work for both parents and employee monitoring? If you used one, how was the result and its functioning?
Well, it depends on what purpose you want to use a monitoring app. Several tools do the job based on what you need.
Like I have been using Xnspy, and now I don’t need to install any other app because it has everything I was looking for. The app works in stealth mode, has a clean and organized dashboard, and is super easy to set up.
Other than that, I use it for Social media monitoring, GPS location, and SIM logs, and it does the job pretty well. So if you are looking for an all-rounder, I’d suggest going for Xnspy.
Pro Tip: Always check your device compatibility with the compatibility checker present on the Xnspy website before installing the app.
Look, man, if you are asking for monitoring apps just because you want to get basic location details, then you can opt for Life360. The app is designed to provide location updates, but the free version doesn’t offer many features, so you may need to upgrade to the premium version to use the app to its full potential.
I have used plenty of monitoring apps, and let me tell you one thing: do your research first. Dont be a naive person who spends money, and in the end, the tool was not even worth it. After dealing with all this trouble, I finally switched to Xnspy.
I am just stating my experience; do what you need to do with this information. 
Just a suggestion, before going for monitoring apps, why don’t you try the Android built-in features? As far as I know, Android devices come with pretty good supervision tools that you can incorporate without spending money on outside sources.
Google Family Link is mostly used in Android devices to manage and supervise device use transparently. It allows you to approve or block app downloads, set daily screen-time limits, schedule locks, and view app usage activity.
Family Link also includes content filters for Google Play, Chrome, and YouTube, plus real-time location sharing. All controls are managed remotely from the phone and are tied to the Google account, making it a free, privacy-compliant option for a basic but effective supervision tool.
I agree with you, @AndroidLab. But the problem with these built-in tools is that they don’t provide real-time monitoring. They are free, but can only be used for surface-level monitoring. That’s why I rely on Xnspy, which provides all the ins and outs of the target device. At least you are getting all the features if you are paying for something. Xnspy adds that extra layer of monitoring that most of the other tools fail to do. 
We tried a few paid apps and honestly went back to Family Link + Find My Device. Less drama, fewer glitches, and no subscription anxiety.
Best setup for most people:
• Family Link for controls
• Find My Device for location
• Conversations for everything else
