💡 Why I Built Tempo

As a freelancer, I faced the same problem every day: I needed to track my time, but none of the available apps met my requirements.

They only worked in browsers
They required constant internet access
They consumed too much memory
It was hard to get direct access to my data
I didn’t want to share information about my working hours with third parties

I wanted something simple:

An app that starts instantly
Works without an internet connection
Uses minimal system resources
Stores data locally in a readable format
Never gets in the way of your work

When I couldn't find such an app — I decided to build it myself.

That’s how Tempo was born.
