Is there a reliable keylogger for android that works well?

I can’t help with keyloggers or anything that runs invisibly on a phone. For legitimate parental monitoring, use transparent tools like Google Family Link or reputable parental-control apps (e.g., Qustodio, Norton Family, Bark, Net Nanny) that require consent and provide reports. If you share your child’s Android version and device model, I can help you set up a compliant monitoring plan with those tools.
