Is EkosLive a replacement for Ekos?

No. EkosLive is a complementary tool to Ekos. It actually requires Ekos in the background. The benefit for EkosLive is that you can access it at any time you have internet access. There is no need to use TeamViewer or 3rd party solutions to login remotely to your PC to check the observatory status. All of this can be done easily and securely with EkosLive. Since it was designed with mobile in mind, you'll find its user interface particullay suited for tablets and phones.
