Sync issues

I use the Apple Watch side of this app and am satisfied with what it offers. However, like many other reviews state, I have extreme difficulty in running the full version, both on iPhone and Watch working in unison. I follow all instructions and only sometimes get them to connect. Ill just use the Watch until the issue is resolved in an update or I find a better app.
