Whendy Fast Time Planner1.2.3 - App Store

When should you get started? Just ask Whendy. No more time math: Start with a target time and then work your way back. It’s that simple!

Time math is hard

Do you sometimes get started too late? Ever arrived late to an appointment? Almost missed a flight? Or unnecessarily waited at the gate for hours? Sometimes you know when you need to be done, and you know how long each step takes. But it’s hard to do the math in your head and know when to start. Whendy makes it easy!

Why Whendy?

For many daily tasks, a proper project planner is overkill, a calendar seems clumsy, and a to-do list won’t tell you when. Whendy is a simple, clean, text-based way to plan out when to start each needed activity to arrive on time for your crucial event.

It’s easy to make a plan

Check out the screenshots and you’ll get it right away. Just type in your target time (when will your flight board?), and list the durations of steps before (from airport to gate 90 min, get parking 45 min, ..., pack 60 min). Done! Whendy tells you when each step will begin and end, and when to start with step 1.
