Estimioo
4.8AI-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.

NimbleRetro
3.8Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs a time-boxed retro through Icebreaker, Ideate, Group, Vote, Discuss and Feedback stages, ending in a 5-Why root cause drill-down on whatever the team voted up. Action items created in the Discuss stage convert directly into Nimble work items (user stories, cards) in the project the retro was created from. There is no separate purchase — Retrospectives ship to every Public SaaS Nimble account by default.
Full review →Summary
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.
NimbleRetro scores 3.8 overall and is best for small agile teams already inside the Nimble suite that want a structured, time-boxed retro ending in a real root cause analysis, with the follow-up landing in the same backlog they already work from. It offers paid plans from $15/mo (up to 20 users).
Estimioo leads on ease of use, retro toolkit, value, fun factor, AI & insights and integrations. NimbleRetro leads on open platform and enterprise-grade.
Across our eight scoring dimensions, Estimioo edges ahead with an overall score of 4.8. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

Estimioo — pros
- + Genuinely cheap — flat <strong>$7/workspace/mo</strong> with unlimited participants, plus a usable free tier; guests join by link or QR with no signup, in five UI languages
- + A real facilitation flow: optional Writing → Voting → Discuss phases with a done-writing signal, host-led card grouping, a 3–10 vote budget and owners on action items
- + Anonymous sessions (or a single anonymous card on a named board), and open actions from earlier retros resurface as a banner when the host starts the next one
- + Unusually fun for the price: 340+ synced icebreakers, twelve ambient and music tracks, emoji reactions on cards and an in-session chat with GIFs
- + One-click Claude retro summary returns team mood, key themes and ranked action items with <em>Add all to board</em>
Estimioo — cons
- − No blind brainstorm — cards appear to everyone as they're written, so the retro page's <em>write first, discuss second</em> pitch rests on the facilitator, not the tool
- − Follow-through belongs to the host, not the team: carry-over runs through a personal action tracker, nothing recurs or can be scheduled, and Team Radar scores don't trend across retros
- − Thin integrations: Slack and Teams are copy-to-clipboard buttons, Jira is planning-poker only, Linear is still "on the way", and a retro exports nothing but a pasted recap — no API, webhooks or MCP
- − No SOC 2, ISO 27001, DPA or data-residency option, and while Enterprise lists SSO, the shipped sign-in offers only Google and email
- − Social proof is entirely unattributed — <em>450+ teams</em>, a <em>4.8</em> rating and a logo wall naming Accenture, Deloitte, Thoughtworks and Xero, with no G2, Capterra or Product Hunt listing to corroborate any of it
NimbleRetro — pros
- + 5-Why root cause analysis is a <em>built-in retro stage</em>, not an afterthought — almost no other retro tool ships one
- + Anonymous voting plus a facilitator-set timer on every stage keeps a 60-minute retro on the rails
- + Action items convert directly into Nimble work items, so follow-up lands in the same backlog the team already works from
- + Included by default in every Public SaaS Nimble account — no separate purchase, no tier upgrade, available to all user roles
- + NimbleWork, Inc. holds its own SOC 2 Type II, ISO/IEC 27001:2022 and ISO/IEC 42001:2023 attestations, with reports on request through its trust center, and supports SAMLv2/ADFSv3 SSO
NimbleRetro — cons
- − The dedicated NimbleRetro iOS and Android apps have been delisted from both the App Store and Google Play, while the product pages still advertise them
- − No health checks, no recurring retros, no async mode, and no documented export of a retro board in any format
- − The platform surface — REST API, outgoing webhooks and the new Nimble MCP server — reaches Nimble cards only; none of it touches a retro, and no AI runs on retro data despite the Retrium comparison page ticking <em>Generative AI</em>
- − Participants are limited to members of the Nimble project the retro was created from, and the module is unavailable outside Public SaaS
- − No rate card: the only NimbleRetro-specific price NimbleWork publishes ($15/mo for up to 20 users) sits on a blog post, and the retro 'pricing' page is a product page with a demo form
