Metro Retro
3.0Rebranded 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 If you are searching for Metro Retro, the product you want is Spreo; the original Metro Retro brand and domain are no longer maintained.

NimbleRetro
3.6Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs structured, time-bound retros through Icebreaker, Ideation, Grouping, Voting, and Root Cause Analysis stages, with anonymous input, action item tracking, and a 5-Why root cause workflow. Native iOS and Android apps complement the web product, and action items convert directly into Nimble workitems (user stories and cards).
Full review →Summary
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 3.6 overall and is best for small agile teams that want a no-frills retro with built-in root cause analysis and a mobile companion app, especially teams already using the wider NimbleWork (SwiftKanban / Nimble) suite. It offers paid plans from $10/user/mo (Nimble Team tier, USD; standalone NimbleRetro is quote-only).
Metro Retro leads on fun factor. NimbleRetro leads on ease of use, value, open platform and enterprise-grade.

Metro Retro — pros
- + The product you remember still exists — it now ships as Spreo (Metro Retro → Ludi, 4 Aug 2025 → Spreo, 1 Jul 2026)
- + The vendor says accounts, boards, data and workflows carried through both renames, and old links redirect
- + Carried its playful templates, session timer and icebreakers into the rebrand
- + Freeform whiteboard canvas that's friendly for engagement-first retros
Metro Retro — cons
- − The Metro Retro brand and metroretro.io domain are retired — the domain 301-redirects straight to spreo.io
- − Two name changes in under a year (Metro Retro → Ludi → Spreo) leave stranded searchers chasing a moving target; bookmarks, runbooks and SSO configs all need updating
- − No standalone free tier under the new brand — a 30-day trial, then paid
- − The old domain isn't a clean redirect everywhere: metroretro.io/pricing returns a stale Spreo <em>Non-prod environment</em> stub instead of forwarding (checked 3 Aug 2026)
NimbleRetro — pros
- + Structured 5-Why root cause workflow built into the retro flow
- + Anonymous input and time-bound stages keep retros focused
- + Native iOS and Android apps for mobile participation
- + NimbleWork runs an annual SOC 2 Type II audit and an ISO/IEC 27001:2022 audit, with SAMLv2/ADFSv3 SSO at the platform level
- + Action items convert directly into Nimble work items, so follow-up lands in the same backlog the team already works from
NimbleRetro — cons
- − Only four templates, and custom templates cap out at four columns
- − No SCIM provisioning or audit logs documented; SSO and the SOC 2 / ISO 27001 attestations sit at the NimbleWork platform level, not the retro module
- − Comparison pages tick 'Generative AI' for NimbleRetro, but no retro AI (clustering, summaries, sentiment) is documented — NimbleWork's AI Agents are a separately licensed add-on aimed at Nimble cards and analytics
- − No documented export of a retro board in any format
- − Thin direct-integration story for the agile stack — no documented Jira, GitHub, Linear, or Azure DevOps hooks for the retro module
- − Participants are limited to members of the Nimble project the retro is created from
- − NimbleRetro's own pricing page is demo-gated; the only published rate card is the Nimble suite's ($10/user/mo Team, $26/user/mo Business)
