When do you actually focus best? I built Peak Hours to find out

Hey makers, a question about how you plan deep work.

Most advice says "do your hardest work in the morning." I wanted my own data instead of a rule of thumb, so I built Peak Hours into the Daily Activity Logger in Algenius (Pro).

How it works:

1. Work like you always do. The logger records your day in the background.

2. Open Focus & Productivity Insights. You get a focus score, your Peak Hours, your longest session, your top tools, and a flag when context switches pile up.

3. Guard that window tomorrow: fewer meetings there, notifications off, the hard task saved for it.

On the real screen in the poster, the peak window is 10:00 PM to 11:19 PM, tagged as a Deep Work Session.

Free stays $0 forever with unlimited screenshots and an advanced premium editor that's fully free. Pro is $15.99/mo with a 14-day trial. Windows and Linux.

I'd love your feedback: when are you sharpest, and what would you want an insights screen to tell you that it doesn't today?
