evridired - so I spent a lot of time looking for the best solution and decided to use refog keylogger for android. Refog is the cheapest and most effective surveillance app on the market. In terms of its functionality, it is not inferior to some other programs and has advanced functions such as keylogging. Also effective is the refog sms tracking app https://www.refog.com/sms-spy.html. The applications are simple and clear. You can install and use it very quickly.
