Chrono is a free, open-source Android alarm and clock app that offers more customization than Google's or Samsung's default Clock apps, including dark mode, Material styling, alarm tagging, and time-of-day icons. It isn't listed on the Google Play Store, so users must sideload it manually to install and update it.
Scientists linked ultra-precise optical atomic clocks located in four different nations and successfully compared their timekeeping with extremely high accuracy. The experiment demonstrated that these clocks, which are far more precise than the cesium clocks defining current international time standards, can be reliably synced across long distances.
A writer reflects on how personal work has evolved over decades, starting with a teenage fast-food job at Roy Rogers and progressing through catering, temp work, teaching, and eventually a career as a creativity strategist. The piece frames Labor Day as an occasion to forecast future goals, backcast past experiences, rest, and dream about what comes next.
OwnTime is a new app that lets users assign daily time budgets to a handful of priorities, running only one countdown at a time so starting one pauses the others. When a budget runs out, the app triggers a real alarm rather than a notification, and everything resets at midnight. It works independently on iPhone or Apple Watch, syncing the two when paired.
Google is rolling out a refreshed Timers tab in its Clock app as part of the September Android Drop. The update flattens the digit style, removes circular backgrounds from the keypad, adds quick presets for 1, 5, 10, and 15 minutes, and moves the start button above the number pad. Multiple active timers now display in a grid instead of a scrollable vertical list.
A photo of juvenile lobsters being reared at the UK National Lobster Hatchery before release into the wild was named a finalist for Ocean Photographer of the Year 2026. The image is part of a broader roundup of standout science photography from the past month, curated by Nature's photo team.
A review piece examines Google's preinstalled Clock app and argues it lags behind specialized alternatives like Alarmy, Chrono and NFC Alarm Clock despite its wide reach on Android phones. The author's top request is adding task-based alarm challenges—math problems, CAPTCHAs, QR or NFC scans, or sliding puzzles—that force users to physically engage before an alarm can be dismissed.
Standards body CGPM will vote in mid-October on ending the leap second, the periodic one-second adjustment used since 1972 to keep atomic clock time aligned with Earth's rotation. The move is being accelerated because the next adjustment could, for the first time, require subtracting rather than adding a second—a scenario computer systems have never had to handle. In its place, officials are proposing a leap hour that would only realign timescales once they drift a full 3,600 seconds apart.
