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, a 41-template sprint retrospective board and async daily standups into one shared workspace. The centre of gravity is still estimation, but the retro module is now a real one: one-click templates, a 2–25 minute session timer, per-card thumbs-up voting, synced icebreakers, ambient audio, and a Claude-powered summary that returns team mood, key themes and ranked action items. What it is not is a facilitation suite — retro cards are attributed rather than anonymous, and there is no grouping, no dot-vote budget and no action-item owners or carry-over between sprints.

Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs structured, time-bound retros through Icebreaker, Ideation, Grouping, Voting, and Root Cause Analysis stages, with anonymous input, action item tracking, and a 5-Why root cause workflow. Native iOS and Android apps complement the web product, and action items convert directly into Nimble workitems (user stories and cards).
Full review →Estimioo scores 4.6 overall and is best for small, distributed agile teams who want fast AI-assisted planning poker and async standups at near-zero cost, plus a genuinely usable 41-template retro board — and who don't need anonymity, grouping, or action-item follow-through across sprints. It offers a free tier.
NimbleRetro scores 3.6 overall and is best for small agile teams that want a no-frills retro with built-in root cause analysis and a mobile companion app, especially teams already using the wider NimbleWork (SwiftKanban / Nimble) suite.

Estimioo leads on ease of use, retro toolkit, value, fun factor, AI & insights and integrations. NimbleRetro leads on open platform and enterprise-grade.
