In our daily activities we often do some important tasks or achievements.
If we want to keep track of important things we have to note it down in a safe place.
I mostly track my achievements like completing any book or completing any course.
I use the Trello App to note down my important achievements.
Before using Trello I note down important things in my diary but in my diary I note down other things as well. So keeping a notebook is also a problem because in some cases you can forget where you place the dairy.
If you change your room or house then there are chances that you lose your dairy.
So it is better to note down your important things in an app.
