Hello, it's not the number of options, but the philosophy behind them, is that both options have to pass through the servers of their respective companies.
Besides, I have found them to be very intrusive software.
I have tried them in several devices and they have only worked in one samsung. Most of my clients have obsolete devices, android v4 and even those programs do not work, or they have not worked for me.
I would like to use something independent, a VNC server, for example, independent of the control of any company.
