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you are searching for Metro Retro, the product you want is Ludi/Spreo; the original Metro Retro brand and domain are no longer maintained.
