Are you one of those who only remembers the obligations when there is no longer the possibility of doing them? Then you can use a program like PesterMe, which works as a reminder, so you are aware of all your pending tasks.
When you run the program, a small window opens with an alarm that will let you know that you have something to do, the alarm being very loud and loud, which will not allow you to ignore it.
When the program is active, a small clock is installed in the taskbar, it is very easy to edit each of the tasks you want to add, being able to repeat the reminder every so often you set.
PesterMe barely consumes system resources, is free and also works without having to install an executable.
You can free download PesterMe 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
