flat.social vs Kaizen

flat.social is a browser-based virtual meeting and events space where people move around shared rooms and talk with nearby participants. Audio volume and video connection respond to proximity. A flat can combine Open Spatial rooms for mingling, Conference rooms for presentations, and Chat rooms for text. Participants can draw, write and add images to shared whiteboards and sticky notes; built-in activities include football, chess, surfing, dice and arcade cabinets. Conference rooms support screen sharing and speaker or gallery layouts. Guests can join from a link, and the service runs in Chrome, Edge, Firefox and Safari. The Free plan costs nothing and allows up to five people at once with unlimited session length. A Day Pass costs $2, paid once, billed at $2 per seat for 24 hours, requires at least 10 seats and supports up to 100 people. Monthly costs $6 a month, billed at $6 per seat per month, with 10 to 100 seats, attendance insights, branding removal, roles and advanced access control, and priority support. Larger capacity can be discussed with the company. Slack users can start a flat with /flat and schedule recurring weekly events.

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. Premium costs €3.99 a month or €39.99 a year; both include unlimited tasks, habits and app blocking, room creation, the full music and background library, and all-time statistics.
