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.

Estimioo scores 4.1 overall and is best for small, distributed Scrum teams who mainly want fast, AI-assisted planning poker and async standups, and are happy with a simple reflection board for retros rather than a dedicated retro suite. It offers a free tier.
RetroFlow scores 3.7 overall and is best for small or ad-hoc teams who want a genuinely free, zero-friction retro board they can share with one link — no signup, no payment and no setup, accepting that there are no integrations, AI or enterprise controls. It offers a free tier.

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
RetroFlow — pros
- + Genuinely free with no paid tiers, no paywalled features and no account required to join a board
- + Anonymous feedback — participants contribute with no signup, email or PII collected
- + Three-step setup — pick a template, share the link, run the retro; participants join with one click
- + Seven ready-made retrospective formats covering the common reflection patterns
- + Real-time collaboration with live notes, dot voting and shared action items
- + Light personalisation — custom column names, 2-6 columns, 7 colour palettes and 48 emojis
RetroFlow — cons
- − No integrations at all — nothing pushes to Jira, Linear, Slack, Teams or any agile-stack tool
- − No AI features (clustering, summary, action extraction or sentiment)
- − No health checks, recurring retros, mood tracking or cross-team reporting
- − No enterprise security or compliance — no SOC 2, SSO, SCIM or audit logs; the privacy policy confirms only HTTPS and Vercel hosting with Google Analytics/PostHog analytics
- − Built and run by a solo developer (Prashant Meena) with no support team or SLA — fine for ad-hoc use, but unsuitable for enterprise procurement
- − Boards are private only by unguessable URL — there are no accounts, so no real access control, invite management or board history
