RADIO TIME CODES, SPELLED OUT A clock sold as "atomic" is really a radio, listening to a distant station that spells out the time one second at a time. TrueOffset now plays those codes, timed to the true second, and shows each one being read as it arrives: WWVB, DCF77, MSF, JJY (40 and 60 kHz), and BPC, plus the codes of WWV, WWVH, CHU, and Australia's VNG. That makes fourteen signals in all, each built from its station's published sound and timing. None of them is a recording. - Set a Radio-Controlled Watch (beta): lay a watch on the speaker and let it listen. It has set a Citizen Eco-Drive in Australia, far out of WWVB's reach. If you try it, tell us how it went. - DCF77 weather: switch it on, and your local forecast rides in the code's weather seconds, the way Germany's station once sent its own. TrueOffset asks for your approximate location only when you turn this on. - The Lincolnshire Poacher: a shortwave mystery, not a time signal. It plays only when you ask for it. ALSO NEW - Help in the app: what an offset is, why clocks drift, what each screen shows, and what TrueOffset asks for and why - On Wi-Fi, a note says how much of the offset can be network delay - A new default reference, ntp.trueoffset.app, a Safran SecureSync 1200 with its own rubidium atomic clock - The Quality ranking names the steadiest of three or more servers - Clearer, higher-contrast text throughout - Public servers now get one request per poll, as their operators ask - TrueOffset is now on the Mac, too, free in the same App Store listing

TRUEOFFSET MASTER CLOCK A tribute to the U.S. Naval Observatory's telephone time service. A tick sounds every second while a voice reads the time: "At the tone, Pacific Daylight Time, 14 hours, 32 minutes, 15 seconds." Five seconds later it does the same for Universal Time. Each beep lands on the true second, timed against your NTP reference rather than your device clock. - Turn it on in Settings > Sound > Time Signal - Announces your local time and Universal Time every 15 seconds - Switch Voice Announcements off to keep just the ticks and beeps - Speaks English with your device's voice; Enhanced and Premium voices sound more natural TrueOffset is not affiliated with the U.S. Naval Observatory. NEW IN 1.2, IN CASE YOU MISSED IT - Time signals: Six Pips (Greenwich Time Signal), WWV, WWVH, CHU, Jihō, and Moscow Six Pips, synthesized to each service's published pitch and timing - Measure with Microphone: finds the delay your Bluetooth or AirPlay speaker adds and starts each pip that much earlier - Initial support for iPhone Duo

TIME SIGNALS TrueOffset can now sound the time. Turn on Settings > Sound > Time Signal and the start of each pip marks the true second, timed against your NTP reference rather than your device clock. - Six signals, synthesized to each service's published pitch and timing: Six Pips (Greenwich Time Signal), WWV, WWVH, CHU, Jihō, and Moscow Six Pips - Hourly signals can sound on the hour, every 15 minutes, or every minute - Plays while TrueOffset is open, even in silent mode, and mixes with your music MEASURE YOUR SPEAKER'S DELAY Bluetooth and AirPlay speakers add their own lag. Tap Measure with Microphone and TrueOffset plays a few test tones, listens for how late they arrive, and starts each pip that much earlier on that output. The audio is analyzed on your device and never recorded or sent anywhere. ALSO IN THIS VERSION - Initial support for iPhone Duo - Quality dashboard cards no longer wrap their labels on narrow screens - The About screen shows the installed version
