To-Do First is an algorithmic ranking To-Do list that ranks your tasks based on Importance, Urgency, Profitability, Pleasure using various user selectable algorithms.

Choose from 12 unique rank algorithms to prioritize the To-Do's that you feel like doing right now.

For example, if you feel like an easy day you can set the rank algorithm to “Pleasure Prioritised”, which gives higher rank to To-Do's that are pleasurable.

To-Do's can be sorted to display work tasks, personal tasks, or work and personal tasks combined. Tasks within these lists can be ordered by either priority rank or due date.

To-Do First also features a unique "Auto Urgency Mode" that automatically increases the urgency of a To-Do each day as it approaches the due date.

“Auto Urgency Mode” features three “Auto Urgency Models” to determine the rate a To-Do’s urgency value increases between the start and due date. The three “Auto Urgency Models” are fast rise, average rise and late rise. Alternately, you can choose to set the urgency of a task manually.

Now an algorithmic ranking To-Do list can prioritize what you should do first!

Features summary:
► Rank Algorithm automatically generates a ranking out of 100 for each task.
► 12 unique Rank Algorithms let you choose what to focus on.
► Sort by Work or Personal, Rank or Due Date.
► Automatically set Urgency with ‘Auto Urgency Mode’.

► To-Do First Review by Alexandre R. Labrie, CEO of The International:

I constantly think about what I have to accomplish first. Finish that report? Contact that external vendor? Work on that business strategy in progress? Prioritizing is central to any executive's work and To-Do First makes that a lot easier. It has taken away the time I used to spend wondering what I should do and it has freed my schedule from tasks I have now realized were not as crucial to our goals.

I usually have my setting on 'importance', but in late evenings, I set it to 'pleasure'. This allows me to work on side projects that I find more stimulating but that nonetheless contribute to our progress. Put simply, this app takes the pain away from prioritizing your work and helps you to work smarter. It is a business tool that increases your efficiency.

For People With HUGE To-Do Lists

This app will not be helpful for people with small to-do lists, but for people like me who find it not unusual to have over 200+ items, the ability to prioritize and rank the list is a true god-send as it helps to avoid the paralysis that comes with an overwhelming number of tasks.

This is also the best companion I have found for David Allen's GTD program for personal organization especially if you are disciplined in making sure that you enter ALL of your tasks and goals and to-do's in the application.

Though the app is perfect for what I need to do, if I may dream, it would be nice to have the ability to create other categories other than Personal and Work as I wear many other hats, and to integrate the app with a calendar would make it the ultimate time/life management tool.

Nonetheless, for this particular reviewer, To-Do First is the only app I will ever need for my iPod Touch.

Nice app, but I think there is a lot of work that has to be done! The look and feel isn't very apple like! Especially the edit screen... Why not put all in table cells like apple does it in the calendar app, for example?!

Also, adding a new todo and than hit the back button adds an empty todo, which is kind of useless!

What I really like, ist the auto urgency mode! This seems to be a very great concept!

Now it's great!

This app is one of the few to-do list apps based on an original concept. It was working really well for me previously, and now with the recent update so you can change the rank algorithm its great.
