Free retrospective timer for agile sprint retrospectives. Time each retro phase (gather, generate, decide, close) to keep team reflection efficient.
Scrum Guide recommends a maximum of 3 hours for a 4-week sprint, 90 minutes for a 2-week sprint, and 45–60 minutes for a 1-week sprint. In practice, 60 minutes is typical for 2-week sprints. A timed retrospective produces crisper insights than open-ended sessions.
Classic 4-L's retro (60 min): Check-in 5 min, Liked (10 min), Learned (10 min), Lacked (10 min), Longed For (10 min), Action planning (15 min). Set the timer for each phase independently. The time pressure prevents the group from dwelling on any single item.
Use dot voting (each person gets 5 votes, marks their top concerns) during the "generate" phase to surface the top 3 items before discussion starts. This prevents the loudest voice from dominating and ensures the timer is spent on the most valued topics.
Use Miro or Mural (virtual sticky note boards) with timed phases. "Quiet writing time" (5 minutes, timer visible) prevents anchoring — everyone writes before sharing. Then rotate through sticky notes. The timer ensures equal attention to all contributions before discussion.
1–3 action items maximum, each with a named owner and a deadline. More than 3 rarely get implemented. Use the last 15 minutes of the retrospective timer to agree on actions — not to generate more discussion. Quality of follow-through matters more than quantity of ideas.
