A side-by-side look at scores, pricing, features and integrations to help you pick the right retrospective tool.

Rebranded twice — Metro Retro became Ludi, now Spreo; the playful retro whiteboard lives on
Metro Retro was a fun, freeform online whiteboard built for sprint retrospectives, known for its playful templates, timer and engagement features. The product has since been renamed twice by its maker, Deqo Software Limited: to Ludi on 4 August 2025, then to Spreo on 1 July 2026 after a trademark cease-and-desist. The metroretro.io domain now 301-redirects straight to spreo.io. If you are searching for Metro Retro, the product you want is Spreo; the original Metro Retro brand and domain are no longer maintained.

Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs a time-boxed retro through Icebreaker, Ideate, Group, Vote, Discuss and Feedback stages, ending in a 5-Why root cause drill-down on whatever the team voted up. Action items created in the Discuss stage convert directly into Nimble work items (user stories, cards) in the project the retro was created from. There is no separate purchase — Retrospectives ship to every Public SaaS Nimble account by default.
Full review →Metro Retro scores 3.0 overall and is best for searchers who remember Metro Retro and need to know where it went — the product now ships as <strong>Spreo</strong>. Go there, or to a dedicated retro platform, instead. It offers custom pricing.
NimbleRetro scores 3.8 overall and is best for small agile teams already inside the Nimble suite that want a structured, time-boxed retro ending in a real root cause analysis, with the follow-up landing in the same backlog they already work from. It offers paid plans from $15/mo (up to 20 users).
Metro Retro leads on fun factor. NimbleRetro leads on ease of use, value, open platform and enterprise-grade.
Across our eight scoring dimensions, NimbleRetro edges ahead with an overall score of 3.8. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.
