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 If you are searching for Metro Retro, the product you want is Spreo; the original Metro Retro brand and domain are no longer maintained.

Simyl Flow
5.5Measure what ships and sticks
Simyl Flow is an outcomes measurement platform for engineering teams in which the retrospective is one of several linked ceremonies, alongside planning poker, demo prep and 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.
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.
Simyl Flow scores 5.5 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 5.5. 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
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, and unfinished actions carry forward with completion-rate tracking — the discussion starts from evidence, and the six-dimension health score answers whether last sprint's change actually landed
- + 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 remote MCP server, generally available and not tier-gated — <em>its endpoint and OAuth 2.1 discovery answer live</em>, with dynamic client registration and 17 read-only tools across 8 data domains (including retros, metrics, actions, poker, effectiveness and coaching), so Claude, ChatGPT, Cursor or Windsurf can query sprint data directly
- + 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 — individual effectiveness profiles and AI coaching notes are private to the developer (and optionally their manager), there are no leaderboards, source code is never stored, and AI runs on Claude via Amazon Bedrock with no data retention
Simyl Flow — cons
- − <strong>You can't sign up yet.</strong> As of October 2026 every CTA leads to 'Join Waitlist', the sign-in page accepts existing accounts only, and the parent company lists Flow as 'Private Preview' — while the pricing page still sells three plans and a 30-day trial. The vendor (Simyl AI, Inc., founded 2024, Toronto) is an unnamed 'small team of engineers' with no G2/Capterra listing, third-party reviews or press coverage
- − Retro toolkit is thin on facilitator staples: no anonymous submission or private brainstorm, no drag-and-drop grouping, no presentation mode, no recurring or scheduled retros, no retro-board timer, and only four built-in formats plus a custom template against 50+ at retro-native tools — and almost no engagement layer (no icebreakers, GIFs, reactions, music or kudos wall), 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 — the vendor is explicit that there are <em>"no surveys, just outcomes"</em>, so there is no survey-based health check, no sentiment analysis and no ROTI; there is no mood capture on the retro board either
- − 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, there is no SCIM, and audit logs appear only as a sales-page offer rather than a plan feature
- − Export is CSV plus PDF reports, and the PDF report download is Growth-tier only; there is no public REST API and no webhooks, and the MCP server is read-only, so nothing can push data back in programmatically
