See the truth
Over time, your random samples build a statistically perfect map of your life.
The Poisson Process
TagTime uses a Poisson process to schedule pings. This means pings occur randomly with no predictable pattern - you can't anticipate when the next ping will come.
Why does this matter? It guarantees that your data is unbiased. Unlike scheduled check-ins which you can anticipate (and subconsciously change your behavior for), random pings capture your true self.

"I thought I worked 60 hours a week. TagTime showed me it was barely 30. It changed how I value my time."
"The only time tracker I've stuck with for more than a month. The randomness makes it a game, not a chore."
"Finally, I can prove to myself that I actually spend way too much time on email. Sobering but necessary."
