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

Metro Retro

3.0

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 If you are searching for Metro Retro, the product you want is Spreo; the original Metro Retro brand and domain are no longer maintained.

Simyl Flow

5.4

Measure what ships and sticks

Simyl Flow is an outcomes measurement platform for engineering teams in which the retrospective is one of five linked ceremonies (planning poker, standups, demo prep, retros, coaching). Retro boards are pre-populated with six sprint metrics pulled from Jira, Linear, GitHub and CI, AI generates candidate cards from the data, and unfinished action items carry forward — all feeding a six-dimension team health score tracked sprint over sprint.

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.

Simyl Flow scores 5.4 overall and is best for engineering orgs that already run retros and want them wired into delivery data — teams asking whether last sprint's improvement actually moved cycle time, review latency or change-failure rate, rather than teams shopping for a better sticky-note board. It offers a free tier.

Metro Retro leads on fun factor. Simyl Flow leads on ease of use, retro toolkit, value, AI & insights, integrations, open platform and enterprise-grade.

Across our eight scoring dimensions, Simyl Flow edges ahead with an overall score of 5.4. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

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)

Simyl Flow — pros

  • + Retro boards arrive pre-populated with six sprint metrics (velocity, cycle time, PRs merged, commits, bug rate, unplanned work) pulled from the tools the team already uses — the discussion starts from evidence rather than recall
  • + Unusually broad delivery-data integration set for a tool that runs retros: Jira, Linear, Shortcut, ClickUp, Notion, GitHub/GitLab Issues, plus GitHub, GitLab and Bitbucket repos and their CI pipelines for DORA metrics
  • + Official MCP server with 17 read-only tools, generally available and not tier-gated, so Claude, ChatGPT, Cursor or Windsurf can query sprint metrics, health scores and blocker summaries directly
  • + Action items carry forward across sprints with completion-rate tracking, and the six-dimension health score answers whether last sprint's change actually landed
  • + Flat per-team pricing ($29–49/team/mo) rather than per-seat, so a 24-person org on three teams pays $87/mo regardless of headcount inside each team
  • + Deliberate privacy architecture — scores are team-level not individual, coaching notes are visible only to the developer and their manager, source code is never stored, and AI runs on Amazon Bedrock with no data retention

Simyl Flow — cons

  • Retro toolkit is thin on facilitator staples: no documented timer or timeboxed phases, no anonymous submission, no drag-and-drop grouping, no presentation mode, no recurring or scheduled retros, and only 5 built-in templates against 50+ at retro-native tools
  • Almost no engagement layer — no icebreakers, GIFs, reactions, music or kudos wall; the product is deliberately metrics-serious, which makes it a poor fit for teams whose retro problem is participation rather than measurement
  • The health score is computed from delivery signals, not from the team — there is no survey-based health check, mood tracking, sentiment analysis or ROTI, so how the team <em>feels</em> is never captured
  • Enterprise claims are self-attested: 'SOC 2 aligned, not certified' and 'ISO 27001 aligned, not certified', inheriting AWS's certifications rather than holding its own; SSO/SAML sits behind a quote-only tier, and there is no SCIM or audit log
  • Export is CSV only, and there is no public REST API or webhooks — the MCP server is read-only, so nothing can push data back in programmatically
  • Young vendor (Simyl AI, Inc., founded 2024) that self-describes as 'a small team of engineers', with no published HQ, named founders, third-party reviews or G2/Capterra presence — a real durability question for procurement
  • Free tier is genuinely small (1 team, 10 stakeholders, 2 retros/month, 1 integration, 90-day retention), and Azure DevOps is still 'coming soon' rather than shipped
