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.

Reetro
6.3Fun, easy and AI-powered online retrospectives
Reetro is a lightweight retrospective tool with a genuinely free tier and a shipped app that runs well ahead of its own marketing site. Three board types — standard, phased (Reflect/Group/Vote/Discuss) and RoundUp, an async video, voice or text interview with AI-generated questions — sit alongside health checks, polls, a happiness calendar and an action tracker. AI meeting summaries, sentiment and emotion trends, auto-grouping and AI action items are quota-limited rather than paid-only, so Free gets a taste. SSO, the Scheduler, anonymous retros and data retention start on the $10/team Pro plan; Pro Unlimited is billed at $49/month per organisation. ISO 27001 is claimed at vendor level; SOC 2 is listed as compliant, not certified.
Full review →Summary
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).
Reetro scores 6.3 overall and is best for small to mid-sized agile teams who want a cheap, AI-assisted retro board — SSO, health checks, the Scheduler and anonymous retros at $10/team/mo, or $49/mo flat for the whole org — and who don't need an API or ClickUp/GitHub/Linear. It offers a free tier.
NimbleRetro leads on open platform. Reetro leads on ease of use, retro toolkit, value, fun factor, AI & insights, integrations and enterprise-grade.
Across our eight scoring dimensions, Reetro edges ahead with an overall score of 6.3. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

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 runs annual SOC 2 Type II and ISO/IEC 27001:2022 audits, supports SAMLv2/ADFSv3 SSO, and publishes a separate EU data region
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
Reetro — pros
- + Genuinely free tier, no credit card — 3 teams, 9 members, 6 columns and 50 guests, plus quota-limited AI (1 meeting summary, 3 auto-groupings, 3 AI action items a month)
- + <strong>SSO, data retention, the Scheduler and anonymous retros all start on the $10/team Pro plan</strong>, confirmed by the app's own upgrade copy
- + Pro Unlimited is genuinely org-wide — the app bills it at <em>$49/month per organisation</em>, not per team
- + RoundUp collects async video, voice or text feedback with AI-generated, editable interview questions — a real async mode, not just a board left open
- + AI meeting summaries carry sentiment, emotion trends (joy/trust/fear/sadness) and participation metrics, and roll up into cross-team comparison views
Reetro — cons
- − The marketing site understates the product: PDF and XLSX export, @mentions, link cards and comparative reporting are all live in the app yet tagged <em>coming soon</em> on the pricing page
- − No public API, no webhooks and no MCP server — nothing can drive Reetro programmatically
- − Confluence and Trello are export-only; Reetro hands you a Word or CSV file and links the other vendor's import instructions
- − Icebreakers are still unshipped — the in-app 'Icebreakers & Games' tiles are badged coming soon and link to a subdomain that no longer resolves
- − No published Reetro-level SOC 2 Type 2 audit (the trust portal lists SOC 2 as 'compliant', ISO 27001 as 'certified'), and no SCIM
- − Anonymity is paid-only, and the Pro Unlimited plan card still reads PER TEAM while the FAQ and the app both say per organisation
