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.

Trune.io
4.1Structured online retrospectives with team radar
Trune (formerly Fraankly) is an EU-built retrospective and team-feedback tool that runs a fixed four-phase session — silent writing, presenting, voting, actions — with 14 pre-built templates plus custom ones, anonymous cards, drag-to-group clustering, dot voting, action items with reminder emails, and team radars including the Spotify Squad Health Check. Hosted in Frankfurt with EU-only application data, available in five UI languages, and exports results to Excel, CSV or an emailed PDF.
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).
Trune.io scores 4.1 overall and is best for small EU-based agile teams that want a simple, <strong>GDPR-aligned</strong> retro tool with templates, grouping, voting, and team radars — and can live with a vendor whose app has not shipped an update since September 2025. It offers a free tier.
NimbleRetro leads on open platform and enterprise-grade. Trune.io leads on ease of use, retro toolkit, value and integrations.
Across our eight scoring dimensions, Trune.io edges ahead with an overall score of 4.1. 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, 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
Trune.io — pros
- + EU/Frankfurt data residency and a GDPR-first posture — the FAQ states no application data is stored outside Europe
- + Per-team (not per-seat) pricing: $19/mo covers unlimited members, and the free tier gives 5 sessions
- + Native two-way Azure DevOps sync on the Enterprise plan — action items out as work items, Done status back in
- + Team radars include the Spotify Squad Health Check plus fully custom radars
- + Ships in five UI languages (English, German, Dutch, French, Italian) and exports to Excel, CSV or an emailed PDF
Trune.io — cons
- − <strong>The product has stood still</strong>: the web app was last deployed in September 2025, the blog stopped in July 2024, there is no changelog, and the Android app is gone from Google Play
- − No SCIM, SOC 2 or audit logs, and SSO only as a bespoke per-customer SAML setup — not enterprise-ready
- − No AI: the code carries a truneGPT chat window, but nothing in the interface opens it
- − Azure DevOps is the only native connector and is Enterprise-only (quote-based); everything else is a single one-way Zapier trigger
