An aspect I'm looking for in certain Mac tools is an option to run automatically. For example, I use the login elements in System Preferences> Users and Groups to launch a variety of apps and tools when my Mac starts. That way email is collected, Dropbox is connected and backup is done automatically. Scheduled tasks that run automatically can save time and not be subject to a memorable memory.
A properly designed and free Mac tool I've recently used is Oliver Matuschin's Task To Dawn. I'm thinking of it as an automatic boot, but it's more of a task planner that denying Mac users will appreciate, but it's okay for the rest of us to use. Task To Dawn can run different scripts, launch programs and tools, even back up a Mac on a schedule.
Open task for dawn. The app will ask to set it to run at boot-up (not a bad idea) and ask to check updates and it's ready to go. Click to create a new task. Give it a name and a description, then set the action, and then set the schedule.
The actions are numerous and varied but I find it especially useful to start AppleScript script at a certain time. Use Task for Dawn to create as many task actions as you need.
Not bad for free, huh?
The only warning I have with the tool is that it is written in Java, which will require an additional download to work with your Mac. Java also means Task Till Dawn also works on Windows PCs (with Java installed).
Java is still popular in enterprise and education, but for Mac and average users, not so much.
