FOCUS ROOMS
Study with me, together, online. Find a study buddy or join a virtual study room:

• See each member's focus tag
• Live timer sync across all members
• Create your own public or private rooms (2-50 members)
• Invite friends with a simple 8-character room code
• Share your active task for accountability

Focus Rooms use body doubling - especially effective as an ADHD focus tool - for accountability without the pressure of video calls.

• Remote workers, freelancers, and work-from-home professionals
• Writers, creators, and developers seeking flow state
• Anyone with ADHD or focus challenges
• Anyone building habits and daily routines

Whether you need a study app for exam prep or a distraction-free timer to beat procrastination, Kaizen adapts to your workflow. No ads. No distractions. Works on phone, computer & web.

More than a simple timer. Kaizen is a complete focus and productivity system.
