For those who rely on precise timekeeping, an atomic clock app is a must-have on their Android device. Whether for scientific research, astronomy, or simply to ensure punctuality, having the most accurate time is essential. With so many apps to choose from, it can be overwhelming to decide which one to download. In this article, we’ll explore some of the best atomic clock apps for Android that you can use to keep your time synced to global atomic clock standards.

10 Best Atomic Clock App Android
Below is a compiled list of 10 Best Atomic Clock App Android for your consideration, which have undergone rigorous testing and evaluation by our team of experts.
1. Atomic Clock
The most accurate time can be displayed by this clock. The app makes a perfect choice for the new year 2020 countdown, birthdays, New Year’s Eve or for daylight saving time changes. The exact time is shown by this app. The current time can be set automatically in the background with the Atomic Clock app. The control buttons can be hidden or shown by tapping the clock. Accurate time is shown in both landscape- and portrait-mode with an option to show or hide milliseconds and 2h and am/pm-mode. Lower display refreshrate value slower drains the battery. The current time and date can be set automatically, but only for root users. A stable wifi or 3G connection should be used for the most accurate time. The NTP-protocol is used for synchronization and internet access is required. The mobile device is used only as a clock generator, and the actual accurate time is obtained from one of the NTP-servers.
2. Atomic Clock – US NIST Time
The exact actual time from several US NTP servers can be shown on this app, based on atomic clocks. The deviation of the device clock from the exact atomic time is also displayed. A New Year’s Eve Countdown function is available. There are 2 operational modes to choose from: Continuous Clock and Time Snapshot. The app is designed to be used as a clock on top of the screen, with the date and time zone provided. Different background colors and images can also be selected. The app contacts 3 different US NTP time servers operated by NIST via network.
3. Atomic Clock & Watch Accuracy
The app has two main features which include detecting and showing the exact time via NTP protocol, which can be used to sync time on various devices, and allowing users to track the accuracy of their wristwatches. The app is able to connect to NTP time servers and show the exact time. It also allows users to track the accuracy of their wristwatch collection and share accuracy data with their friends on social networks. The basic app functionality is free, while premium functionality is a paid feature. If any bugs are found or improvements are suggested, the developers can be contacted.
4. Atomic Time – NTP Clock Sync
The most accurate time can be obtained using this super precise atomic clock, which is synced with NTP servers to calculate the difference with the device’s time. The accuracy of watches can be checked or the time of devices can be set using this app.
5. Atomic Wall Clock
An accurate atomic digital wall clock can be created from an old android phone/tablet with the largest font to fit the screen. The app will sync with NIST Internet Time Server every 5 minutes for the most accurate time. The difference found between the device clock and atomic time will be shown on the bottom right corner to verify the sync. The Pro version offers more options.
6. AtomicClock: NTP Time
The accurate time from NTP servers, which get the time directly from atomic clocks, can be provided by AtomicClock. The current precise time in the correct time format is available, along with an analog and digital clock, customizable widget with time and date, and different clock faces to choose from. You can switch between local time and UTC, 24-hour and 12-hour clock, and sync your physical watches and clocks. Technical information such as round trip time or stratum, as well as the Greenwich Time Signal, are also available. AtomicClock is considered to be the most accurate time on Android.
7. radio watch sync
A Casio G-Series radio watch was owned, but it could not receive radio waves from the time signal station. An application was created to solve the issue after conducting some research. The application can simulate timing signals and accurately calibrate the time. The usage method is to adjust the phone volume to the maximum, switch the watch/clock to manual wave receiving mode, click the start button, and place the watch/clock near the phone speakers. The synchronization process takes 3-10 minutes. Some matters needing attention are to use the software in a quiet environment to avoid signal interference and adjust the phone volume to the maximum. The software supports simulation of all types of Time Wave Signal such as China BPC, USA WWVB, Japan JJY40/JJY60, Germany DCF77, and British MSF. A unique Beast Mode provides higher frequency simulation signals and faster sync. For any use questions, contact information is provided.
8. Smart GPS Time
The correct time on your Android device can be checked with Smart GPS Time which uses atomic clock from GPS satellites. Time synchronization is also available for rooted devices with BusyBox installed to ensure app security. If the app does not work, the developer should be contacted for improvement rather than just leaving a comment. Users are encouraged to rate the app if they like it.
9. Smart Time Sync
The Smart Time Sync app allows the clock on your Android device to be checked and synced with GPS or Internet (NTP/HTTP). Time zone can also be detected by location and a time signal is available. The app has a very small memory footprint and can automatically switch to HTTP time source if NTP one is unreachable. However, if your device is not rooted, you can only sync in manual mode. The app also allows you to click on the timezone field to follow the guide or install Smart Time Sync TZ data. If the app helps you, please rate it 5 stars only. If it doesn’t work, email the developer instead of leaving a negative comment. The free version’s background sync feature is seven days limited.
10. Time Calibrator
The user is welcomed to Time Calibrator, which has been designed to provide precise time information to people worldwide by automatically connecting to the atomic clock server in Switzerland. The exact local time and date are displayed, and AtomTime i-Atomic watches receive the information via light signals through quantum technology, communicating directly from the NTP server at the speed of light.
