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

AI-powered planning poker, retrospectives and standups for agile teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker and a 42-format sprint retrospective board into one shared workspace. Estimation is still the centre of gravity, but the retro board caught up in September 2026: optional Writing → Voting → Discuss phases with a shared timer, anonymous sessions or single anonymous cards, host-led card grouping, a 3–10 vote budget, action-item owners, and a carry-over banner fed by the host's personal action tracker. A Claude-powered summary returns team mood, key themes and ranked action items. What it still lacks is blind brainstorming, recurring retros, health-check trends and any retro export beyond a clipboard recap.

Measure what ships and sticks
Simyl Flow is an outcomes measurement platform for engineering teams in which the retrospective is one of several linked ceremonies, alongside planning poker, demo prep and coaching. Retro boards are pre-populated with six sprint metrics pulled from Jira, Linear, GitHub and CI, AI generates candidate cards from the data, and unfinished action items carry forward — all feeding a six-dimension team health score tracked sprint over sprint.
Full review →Estimioo scores 4.8 overall and is best for small, distributed agile teams who want AI-assisted planning poker and a capable 42-format retro board in one workspace for a flat $7 a month — and who can live without blind brainstorming, recurring retros, health-check trends or real Slack, Teams and retro-side Jira integrations. It offers a free tier.
Simyl Flow scores 5.5 overall and is best for engineering orgs that already run retros and want them wired into delivery data — teams asking whether last sprint's improvement actually moved cycle time, review latency or change-failure rate, rather than teams shopping for a better sticky-note board. It offers a free tier.
Estimioo leads on ease of use, retro toolkit, value and fun factor. Simyl Flow leads on AI & insights, integrations, open platform and enterprise-grade.
Across our eight scoring dimensions, Simyl Flow edges ahead with an overall score of 5.5. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.
