A simple, honest task timer
TaskScience connects to a Google Calendar you own, lets you start planned or newly created tasks, and writes completed work periods back to that calendar.
Breaks can remain inside a tracked event. Distractions and task-switch gaps are excluded. Repeated tasks keep an explicit identity so their average duration and duration-over-date chart stay meaningful.
Google data use
TaskScience requests permission to list calendars and manage events only on calendars the signed-in person owns. Calendar requests go directly from the phone to Google.
