To get the most accurate time, it's best to use the app in a stable Wi-Fi or good 3G/LTE reception. In areas with poor reception, the time may be slightly inaccurate.

Technical information:

The time is synchronized via NTP servers and therefore requires the internet. The app uses your mobile phone only as a reference clock; the accurate time comes from the NTP server.
