Do someone know how to make squre apps on the No.1 D5?

Another thing, i like very much the interface(features, design, quick settings) of the Zeblaze Blitz.

Do you think we can copy apps from there to make the No.1 D5 similar?

The best way I’ve seen to use any app on a round watch is using the Xposed One-Hand Mode module. If you search this community, there are posts about how to set it up. You have to pay for the premium app so you can blacklist certain apps (some apps work well without it, of course).
