Web site on mobile device is different

When logging on to my web site on a mobile device, the entry point is actually a list of posts within the web site, not the home page itself. I use Colorway Theme, and I’m happy to switch to a more mobile friendly theme if this current one is not flexible. Alternatively, I’d be happy to know if the Colorway Theme can be made mobile friendly.
My site is alkpurusha.net.
