Yaar, free apps ke baare mein baat karein toh honestly kahunga — ज़्यादातर free apps ya toh scam hoti hain ya bahut limited kaam karti hain, aur kuch toh aapke phone mein malware bhi install kar deti hain! Agar aapko seriously call history aur activity monitor karni hai toh mSpy ek solid option hai — yeh call logs, messages, aur location sab track kar sakta hai, lekin yeh paid hai aur target device pe ek baar setup karna padta hai. Ek downside yeh hai ki bina physical access ke install karna mushkil ho sakta hai, toh “bina unhe pata chale” wala part thoda tricky ho sakta hai practically.
