ALTime™ Time

Read full description

If you’ve ever been late to watch, missed a wake-up alarm, got bit by DST or dealt with confusion around ship time changes, ALTime™ is the solution. No Data Required ALTime™ does not require cellular service, data, Wi-Fi, or GPS to function. It is a professional tool you can rely on underway or in domestic and foreign ports. Set It & Forget It Time Changes Your phone can be used without data/internet, but you still have to remember to manually change time after the ship does.  ALTime™ allows you to schedule time changes within the app so they occur exactly when the ship changes time, keeping your phone in sync with the ship. Customizable Time Changes Whether the ship changes time by one hour or 20-minute increments per watch, ALTime™ allows you to schedule time changes using any increment, reliably and repeatedly. Alarms You Can Rely On Alarms set in ALTime™ are tied to the ship's time within the app — not your phone's time — so they remain correct through time changes and eliminate the need for complicated alarm setting math. ALTime™ Features: • No cellular, data, Wi-Fi, or GPS required • Keeps alarms synchronized with ship time • Supports scheduled time changes in any increment • Eliminates daily manual time changes • Unaffected by Daylight Saving Time (DST) • Allows your phone’s system time and date settings to remain unchanged, so you don't lose track of the ship's time when you have service again.
