Think you were focused? Really?

Traditional Timer Limitations

The timer keeps running even when you look away. Checking your phone or zoning out still counts as "focus time".

The Remote Work Dilemma

It's hard to prove how much you actually worked. Even you don't know exactly how focused you were.

The Self-Deception Trap

There's often a big gap between "feeling productive" and actual productivity.
