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. Is Whendy for you? • Are you frustrated by time math where you are adding or subtracting times? • Do you like the effectiveness of a to-do list? • Do you like to keep it simple yet well thought-through? Then yes, Whendy is for you! *Whendy Premium*  • import events from your calendar.

Time is the most important resource we have. And yet, it is often our biggest barrier. How many times have we complained about not doing something because we ran out of time in our busy schedules? There are 168 hours in a week. Assuming you sleep for 8 hours a day and work for 8 hours Monday-Friday, plus 2 hours of household chores (such as eating, shopping, cleaning, etc.) a day, you would still be left with 58 hours of free time in a week. That time can be spent doing anything you want, such as spending time with friends and family, exercising, or even simple leisure like TV or video games. So the math says that we have over a full work week to spend doing whatever we want, and yet it always feels like we don't have enough time. So where does this time go? Want to lose weight? Track how many calories you eat. Want to spend less money? Track how much you spend each week. Want to use your time better? Track how you are actually using it. Studies show that just the simple act of tracking a habit can lead to positive change, encouraging people to become more conscientious of the decisions they are making. The answer of where we actually spend our time varies for everyone, but one thing remains true for all of us: it is impossible to really know where our time goes without taking the effort to actually track it. 10MB was created so that people would be able to regain control of their time. The app was built under the premise that most of the things we do in a day can be tracked using ten minute blocks. By tracking how we actually spend every 10 minute block during our day, we can identify the hidden time sinks in our lives and use our time on activities that are actually a priority for us. 10MB makes this process as simple as possible, making it easy to select each block and choose its time category.
