Overtime Tracker vs standard approaches (notes / pen and paper).

Pen and paper are the oldest way to manage your work.
You can write down anything:

Time tracking
To-do lists
Short notes during the work process

You simply take a pen and write things down, cross them out, sometimes sketch something.

From a psychological perspective, this is one of the most effective ways to organize your thoughts. This habit is formed at school: as soon as a pen or pencil is in your hand, your brain switches into work mode.

Pros of this approach:

Focus (you automatically concentrate on making a list once you’ve picked up a pen)
Simplicity (if you can write, you’re already halfway there)
Complete freedom (only your imagination limits what you can do)

Cons:

Lack of structure (without a long-standing habit of note-taking, creating a clear plan can be difficult)
Hard to make changes (you can use a pencil, erase, rewrite… but it takes time and isn’t very convenient)
Difficult to track time
Not always convenient (pen and paper aren’t always nearby)
Easy to lose (and it’s also easy to get confused in your notes)

Overall, the habit of keeping paper notes will never truly compete with any system or service.
However, digital tools can be a great complement, making planning much more convenient.

For example, the Overtime Tracker service already provides a system where you, step by step:

Create a task list
Plan time and execution order
Track all processes in one place, including working time, time per task, and overtime
Analyze the results of the workday after it ends

You can always stick with the planning method you’re used to.
But we recommend trying to move detailed planning into a service where it’s easy to make changes when things don’t go as planned and get a clear report on the work you’ve done — to improve your work habits and processes.
