Whenr Whenr vs ShareTimers

Doing math with dates and times is hard. Whenr Whenr makes it easy, with a simple calculator-style interface for dates, times, durations, and unit conversions. There are no awkward forms, no modes to switch between, and no workflows to learn. Just type in your values, select the function you want to apply, and get your answer. With Whenr Whenr you can: - Answer time questions quick and easy. For example, calculate “how long is it from now until 7:42?” or “what time will it be in 4 hours and 47 minutes?”? - Count days between dates, add weeks to a date, or work across months without manually counting. - Make schedules easier to reason about. Figure out equal turns, manipulate durations, split time fairly, and keep plans running smoothly. - Make weird durations readable. Convert amounts like 400 hours into weeks, 5,000 minutes into days, or 10,000 seconds into hours, so you can actually think about them. And it does all this in a familiar calculator-style interface - not a maze of tabs and dropdowns. There's no mode switching, no confusing forms, and no translating your question into an app's weird logic. You just enter dates and times using the keypad and get the right answer fast.

Every timer app counts down for one person. ShareTimers counts down for everyone. Set a timer, tap share, and send the link to anyone. They see the exact same countdown, ticking live on their screen, in the app or right in their browser. No account, no sign-up, no invite to accept. SHARED, LIVE, AND EDITABLE A ShareTimers link isn't a screenshot of a timer. It's the timer. Anyone holding the link can add a minute, pause it, resume it, or rename it — and everyone watching sees the change instantly. When the roast needs another ten minutes, whoever's at the oven adds them, and the whole table knows. SHARED STOPWATCHES TOO Counting up works the same way. Publish a running stopwatch, share the link, and everyone follows the same elapsed time and the same laps — useful for races, drills, practice runs, and anything you'd otherwise be calling out splits for. NO ACCOUNTS. EVER. There's no login, no profile, and no friend list. Holding the link is the whole permission model. That means you can send a timer to someone who's never heard of this app and they're watching it two seconds later. WORKS EVERYWHERE iPhone, iPad and any web browser. People without the app just tap the link and watch the countdown on the web — nothing to install. Links in Messages unfurl with a live preview, and tapping one opens straight to the timer if you have the app. NOTIFICATIONS THAT KEEP UP Get notified when your timer ends, even if the app is closed. If someone extends or pauses the timer, your notification reschedules itself automatically — you're alerted at the real end time, not the old one. BUILT TO FEEL NATIVE Clean, familiar design that matches the system clock you already know. Timers and stopwatch in one place, recent timers a tap away, and nothing you have to learn. GOOD FOR • Cooking together, one timer, everyone in the kitchen • Laundry, dishwashers, and anything that's "done" for the household • Workouts, rest intervals, and circuit training with a partner • Study sessions, Pomodoro blocks, and focus sprints with a group • Meetings, talks, and speaking slots where someone needs to see the clock • Games, debates, and turn timers everyone can watch • Kids and chores, without handing over your phone • Races and drills, with shared laps on a shared stopwatch Set it once. Share it everywhere. Everyone stays on the same clock!
