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.

RetroFlow is a free, no-signup retrospective board built by solo developer Prashant Meena, with colourful boards, real-time collaboration, 11 ready-made templates plus a custom board builder, anonymous feedback, unrestricted upvoting, drag-to-move between columns, action items and PDF/Excel export.

The board is desktop-only — any viewport under 768px is blocked outright.
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).
RetroFlow scores 3.4 overall and is best for small or ad-hoc teams on laptops 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 is no timer, no phone support, no integrations, no AI and no enterprise controls. It offers a free tier.
NimbleRetro leads on integrations, open platform and enterprise-grade. RetroFlow leads on ease of use, value and fun factor.
Across our eight scoring dimensions, NimbleRetro edges ahead with an overall score of 3.8. 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
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 in one click and notes sync live
- + Eleven ready-made formats plus a Custom Board builder (2-6 columns, 7 palettes, 48 emoji) with reusable saved layouts
- + <strong>Unrestricted voting</strong> — no vote budget, no phase gate, and you can upvote your own cards; cards also drag between columns
- + PDF and Excel export of the finished board — the only route to getting your data out, and it works
RetroFlow — cons
- − No timer or phase controls — <em>still</em> nothing in the shipped app, and two timer requests raised in July 2026 sit unshipped as <em>Planned</em> on the vendor's own public roadmap
- − <strong>Desktop-only</strong> — every board route hard-blocks viewports under 768px with a 'Whoa, tiny screen detected' overlay, even though the marketing FAQ promises a fully responsive phone experience
- − No grouping of similar cards, no in-column reordering and no carry-over of previous action items; the 'Present' button is still badged SOON
- − No integrations at all — nothing pushes to Jira, Linear, Slack or Teams, and there is no public API, webhooks or AI
- − No health checks, recurring retros, mood tracking or cross-team reporting
- − Solo-developer project with no support team, SLA, SOC 2, SSO or GDPR statement — support routes to a personal WhatsApp number and LinkedIn DMs, and the free-tier backend still shows a ~10s cold start plus a first-load error
