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 rebranded twice by its maker, Deqo Software Limited: to Ludi in August 2025, then to Spreo. The metroretro.io domain now 301-redirects all the way through to spreo.io. If you are searching for Metro Retro, the product you want is Ludi/Spreo; the original Metro Retro brand and domain are no longer maintained.

NimbleRetro
3.0Time-boxed retros with 5-Why root cause analysis

Native iOS and Android apps complement the web product, and action items convert directly into Nimble workitems (user stories and cards).

Metro Retro — pros
- + The product you remember still exists — it's now called Spreo (renamed from Ludi on 1 July 2026)
- + Carried its playful templates, timer, GIFs 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 now redirects through to spreo.io)
- − Two brand changes in under a year (Metro Retro → Ludi → Spreo) can leave stranded searchers chasing a moving target
- − No standalone free tier under the new brand — it's a 30-day trial then paid
- − Not a dedicated retro platform — it's a general whiteboard you adapt for retros
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
- + GDPR compliant; sits under NimbleWork's ISO 27001 / SOC umbrella at the platform level
NimbleRetro — cons
- − Only four templates, with stage flexibility limited to column count
- − No SSO/SAML, SCIM, or SOC 2 Type 2 attestation specific to the retro product
- − Vendor now markets 'Generative AI' but no concrete retro AI (clustering, summaries, sentiment) is documented — treat as unverified
- − 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
- − Pricing not transparently published; demo-gated (third parties peg it around $8/user/mo)
