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.

I’m self employed and it keeps me organised through all work and home things I need to juggle. Highly recommend it! ### 5/5 — Exactly what i needed, but…. *2024-04-14* I love this, but would love it more if I could save multiple of these “mini-timelines” for reuse. One instance where i would re-use a list is any time I’m catching a flight somewhere and depending on which airport I’m departing from, the list looks different. It helps me to stay on track and have checkpoints to know I’m at the right place at the right time. Such as leaving the house, car parked, on the shuttle, in the terminal, bags checked, at the gate etc. Checking back again. I’m still here and would still love this feature to be added 4/13/2024 **Developer response:** Good news at last - check out 1.2.0, you can now have multiple plans in Whendy! ### 5/5 — Exactly what i needed, but…. *2024-02-22* I love this, but would love it more if I could save multiple of these “mini-timelines” for reuse. One instance where i would re-use a list is any time I’m catching a flight somewhere and depending on which airport I’m departing from, the list looks different.

Such as leaving the house, car parked, on the shuttle, in the terminal, bags checked, at the gate etc. ### 5/5 — Calendar integration takes this app to another level *2023-03-07* Whendy is super specialized in that it acts like a day time calculator. For those looking for time blocking solution, Whendy makes it as easy as jotting down your plans for the day and sending them to your calendar. This is honestly incredible. I wish other apps would take this concept and feature to build a more complete task and event management solution. But I’m very content with Whendy as a solution for this, as the ability to bulk export tasks/plans as events, choose which calendar they apply to, and set alarms without ever leaving the app is some of the most clever functionality I’ve seen in a while. I’m not sure what direction the developer is going to take the app, but there’s a lot of potential growth options, including reminders integration to preset tasks. Though, that’s not at all necessary. Anyway, thank your building such a great app! ### 4/5 — Great app, but... *2023-03-07* Would love to be able to save multiple "sequences" to drop an event on to, or even just shortcut/url scheme functionality to open the app with a provided set of text **Developer response:** Thanks for the interesting suggestions! Please consider sending me an email through the in-app settings/contact button and let me know your intended use cases. ### 4/5 — Great functionality *2023-02-10* This is such a simple and useful app. I’ve been looking for something like this a long time. It’s super simple to make a plan, meeting agenda or see how long a set of activities might take. Plus the ability to set an anchor to plan forward o backward from is helpful. However, the is very limited because it’s designed for single use. You can’t plan more than 1 sequence on the main screen and you can’t save a plan to use later. My work around is to copy the text to a journal app so that I can reuse a plan. Another enhancement that would be great is the ability to copy the plan without the duration at the end (to just copy the time and activity). That would make copying the results into more professional communications easer to do with minimal editing. **Developer response:** Thanks for your detailed feedback and interesting suggestions. Please consider sending me an email through the in-app settings/contact button so we can talk more! ### 5/5 — Fantastic App With Simple Functionality *2023-01-18, version 1.0.5* Whendy is something I didn’t realize I needed. I don’t use it every day, but when I do — it’s great. I can schedule my day from start to finish while considering how long each task/event will take. There are a few clever features slipped in, such as the calendar event integration. Overall, it’s a great app! ### 5/5 — Simple and does the trick! *2022-12-11* I love it! So simple. This is exactly what I was looking for! ## Frequently asked questions about Whendy Fast Time Planner ### How does Whendy help me plan my time?
