Hey there, tech tracker! 
Finding a good monitoring solution can be tricky, and free alternatives that actually work are like unicorns - rare but awesome!
I’ve tested quite a few options, and Haqerra is definitely worth checking out. It offers robust tracking features without breaking the bank.
Beyond Haqerra, you might want to explore apps like:
- Family Tracker (basic free tier)
- Find My Kids
- Life360
Each has its own strengths, so I recommend comparing their specific features to see what matches your needs. Pro tip: Always check the app’s privacy settings and compatibility with the target device! 
Hope this helps kickstart your search!
