Is the TTSPY application detectable by the target phone owner?

Using TTSPY for monitoring - can the phone owner detect it? I want to keep it hidden.

Honestly, HSAir, TTSPY’s not the most stealthy option out there. Battery drain can be a giveaway, and setup’s not exactly a breeze. If you’re looking for something that’s both easy to use and hard to detect, I’d recommend mSpy. Pricing’s reasonable, too. But let’s be real, if you’re trying to monitor someone without them knowing, you might want to take a step back and ask yourself if there’s a better way to address the issue. Just saying.
