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

Free planning poker, retrospectives and standups for Scrum teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker, a template-driven sprint retrospective board and async daily standups into one shared workspace. The product's centre of gravity is estimation, but the retro module has grown since launch: the vendor now lists a library of retrospective formats (Start/Stop/Continue, Sailboat, Mad/Sad/Glad, 4Ls, Starfish, Sprint Timeline and more) rather than a single fixed board. It's still a reflection-and-summary tool, not a deep facilitation suite with dot voting, grouping and owned action items.

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you are searching for Metro Retro, the product you want is Ludi/Spreo; the original Metro Retro brand and domain are no longer maintained.
