Estimioo
4.1Free planning poker, retrospectives and standups for Scrum teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker, a basic sprint retrospective board and async daily standups into one shared workspace. The product's centre of gravity is estimation; retrospectives are a real but thin module — a single <strong>went well / didn't go well / improve</strong> reflection board with session summaries, not a deep retro toolkit.

Full review →Summary

Retrium scores 5.1 overall and is best for scrum masters and agile coaches who want a focused, retro-only tool with strong facilitation guardrails and a built-in Team Radar. It offers paid plans from $39/mo.
Estimioo leads on value and AI & insights. Retrium leads on ease of use, retro toolkit, fun factor, integrations and enterprise-grade.

Estimioo — pros
- + Genuinely cheap — flat $7/workspace/mo Team plan (not per-seat) and a usable free tier
- + Fast, no-friction planning poker with multiple scales and hidden-until-reveal voting
- + AI story-point suggestions and estimation-accuracy tracking, powered by Claude with zero data retention
- + Guests join without signup via link or QR code — low overhead for distributed teams
- + Three ceremonies (poker, retro, standup) in one shared workspace
Estimioo — cons
- − Retrospectives are a single fixed went-well/didn't/improve board — no template library, dot voting, grouping, anonymity, timer or action items with owners
- − AI is aimed at estimation, not retros — no theme clustering, sentiment or retro summaries
- − No Slack/Teams, Confluence, GitHub, Linear or Azure DevOps integrations; Jira is a paste-URL preview for poker only
- − No SSO, SOC 2, audit logs or published data-residency — not built for enterprise procurement
- − Free sessions expire after 1 hour and cap at 5/month; no recurring retros or persistent retro history
Retrium — pros
- + Battle-tested five-phase guided facilitation flow
- + Anonymous brainstorming and grouping by design
- + Persistent team-room action plan that carries forward between retros
- + Team Radar covers psychological safety and custom health checks
- + Per-team-room pricing with unlimited users on every plan
Retrium — cons
- − No free tier; 30-day trial only
- − Integrations are thin beyond Jira Cloud and a <em>still-beta</em> Slack app
- − <strong>No AI features at all</strong> — no summary, clustering, action-item extraction or insights
- − No native Microsoft Teams, Azure DevOps, GitHub, Linear or Confluence integration
- − Public shipping cadence has slowed — no 2025 changelog or product blog activity visible
- − Retro-only scope; no planning poker, kudos, icebreakers or whiteboard
