Kaizen vs StudyStream

Kaizen is a focus and study app built around a Pomodoro timer, task and habit tracking, and camera-free Focus Rooms. The timer has presets, custom sessions from 5 to 180 minutes, and stopwatch mode. Rooms hold 2 to 50 people; users can join public rooms or private rooms with a code. There is no video or microphone, and members see one another’s status and focus tag. Tasks include an Inbox, subtasks, priorities, due dates, estimates and automatic time tracking. The free plan allows up to 7 active tasks, 5 habits, blocking for 3 apps, and statistics covering the last 30 days. App blocking is available on iOS and Android, not web or Windows. Kaizen runs on web, iOS, Android and Windows, with account data syncing across platforms. The free plan is free.
