The brightness of my display fades in and out. It moves from bright to less bright. Is this normal?

There is at least one pattern of color reproduction where you can see that behavior. I believe there are seven different states that you can place the Nixie clock into for the display of the time. One would be static or just one color, another would be rainbow, etc. You can refer to the manual that came with the clock, or connect to the clock directly using Bluetooth and browsing to the clocks IP address and you're able to make adjustments there, if you're able to read Chinese. 🙂 (Google translate helped me there.)

The manual says that it can connect with a phone. Is there a phone app?

Hello customer, You can connect the wifi clocteck. The phone will automatically pop up the clock control page. Best Regards, ClocTeck
