A normal timer counts down from a number you choose. A reverse countdown starts from a fixed moment (the flight, the appointment, the school bell) and works back to when you need to begin.
Countdowns people build
A regular timer answers “how long from now?” You give it 40 minutes and it spends 40 minutes. That can be useful, but it only knows what you told it.
A reverse countdown works from the other end. You give it the fixed point (boarding at 3:00, the appointment at 2:15, dinner on the table at 6:30) and it counts down to that. The number on the screen is how much time you have left until something real.
Knowing there are three hours and forty-five minutes until your flight does not tell you when to start packing. Three hours can feel like plenty until packing, showering, and the drive eat through it. What helps is knowing when each step should start.
Remembering the deadline is easy. The start times behind it are the ones that usually go unplanned, and those are what decide whether you make it.
You set the moment you need to be ready. You list the steps and roughly how long each one takes. Ready Time subtracts them from the deadline, in order, and gives every step a start time.
Then each step gets an alert that says “time to begin,” not “time is up,” with the countdown to the deadline right there in the notification: Start packing. Flight in 3h 45m.
One deadline, six countdowns. Change the boarding time and every start time above it moves with it. If the drive is really 55 minutes instead of 40, the whole plan shifts earlier without you recalculating anything.
Get a nudge at the right moment, while there's still time to act.
Each step gets its own alert, so you know what's next and how long you have.
“I get so tired of counting backward to when I should start my task. This app is the solution.”App Store review
A timer that counts down to a fixed point in time rather than from a duration you enter. Instead of “40 minutes starting now,” it holds a moment (3:00 PM, tomorrow at 8:15) and shows how much time is left before it arrives. Backward planning apps go one step further and count back through a list of tasks, so each task gets a start time of its own.
Ready Time does, and it counts down to every step before it too. You enter the time you need to be ready, add the steps that have to happen first, and it works out when each one starts. Every step gets an alert at its start time, with the time remaining until the deadline shown alongside it.
Event countdown apps count days until a wedding, a holiday, or a trip. They're for looking forward to something. A reverse countdown timer works at the scale of a single afternoon: the flight is today, the countdown is in minutes, and what you need is a nudge that says start now.
Yes. A plan is a sequence of steps, and each one has a start time and an alert. You don't have to set six timers by hand and hope they line up. You set one deadline, and the steps arrange themselves behind it.
Repeating plans are part of the one-time Premium unlock, so a weekday morning countdown gets built once and shows up every weekday after that. The core of the app (deadlines, steps, backward math, and alerts) is free, and there's no subscription.
If you're flying, like the plan above, the per-airport pages pre-fill it with your airport's numbers. For a visual countdown disk, see the Ready Time vs. Time Timer comparison, or browse all app comparisons.
