I really like this clock mainly for the color options, the accuracy and the precise digit increments. One of the best overall clocks on the Play Store.

app was great now the time is way too inconsistent. I used this app everyday to mark up for work and then it just stopped being a trustworthy clock. time is never correct always off by -120ms and worse it won't connect to servers half the time

I am pretty confused. The offset shown is the difference between your system clock and the NTP time. It's not an indication of the NTP time is accurate or not. And the app can do nothing about if the NTP servers aren't responding to the apps requests. you can always pick another server in the app settings. Unfair review...

Loving the App & Premium features. Please add the option to get Time from GNSS Satellites. The feature is so interesting & very few Apps are having that. Don't change the App name.
