Reetro vs Simyl Flow

A side-by-side look at scores, pricing, features and integrations to help you pick the right retrospective tool.

Reetro

6.1

Fun, 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 and anonymous retros start on the $10/team Pro plan; data retention needs Pro Unlimited, billed at $49/month per organisation. ISO 27001 is claimed at vendor level; SOC 2 is listed as compliant, not certified.

Simyl Flow

5.5

Measure what ships and sticks

Simyl Flow is an outcomes measurement platform for engineering teams in which the retrospective is one of several linked ceremonies, alongside planning poker, demo prep and coaching. Retro boards are pre-populated with six sprint metrics pulled from Jira, Linear, GitHub and CI, AI generates candidate cards from the data, and unfinished action items carry forward — all feeding a six-dimension team health score tracked sprint over sprint.

Summary

Reetro scores 6.1 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.

Simyl Flow scores 5.5 overall and is best for engineering orgs that already run retros and want them wired into delivery data — teams asking whether last sprint's improvement actually moved cycle time, review latency or change-failure rate, rather than teams shopping for a better sticky-note board. It offers a free tier.

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

Across our eight scoring dimensions, Reetro edges ahead with an overall score of 6.1. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

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, 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
  • − Slack and Teams notifications are sold, but the shipped app has no way to connect either; Confluence and Trello are export-only, a Word or CSV file plus a link to the other vendor's import instructions
  • − No playable icebreakers: the in-app 'Icebreakers &amp; Games' tiles link to four game subdomains, none of which resolves any more
  • − 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

Simyl Flow — pros

  • + Retro boards arrive pre-populated with six sprint metrics (velocity, cycle time, PRs merged, commits, bug rate, unplanned work) pulled from the tools the team already uses, and unfinished actions carry forward with completion-rate tracking — the discussion starts from evidence, and the six-dimension health score answers whether last sprint's change actually landed
  • + Unusually broad delivery-data integration set for a tool that runs retros: Jira, Linear, Shortcut, ClickUp, Notion, GitHub/GitLab Issues, plus GitHub, GitLab and Bitbucket repos and their CI pipelines for DORA metrics
  • + Official remote MCP server, generally available and not tier-gated — <em>its endpoint and OAuth 2.1 discovery answer live</em>, with dynamic client registration and 17 read-only tools across 8 data domains (including retros, metrics, actions, poker, effectiveness and coaching), so Claude, ChatGPT, Cursor or Windsurf can query sprint data directly
  • + Flat per-team pricing ($29–49/team/mo) rather than per-seat, so a 24-person org on three teams pays $87/mo regardless of headcount inside each team
  • + Deliberate privacy architecture — individual effectiveness profiles and AI coaching notes are private to the developer (and optionally their manager), there are no leaderboards, source code is never stored, and AI runs on Claude via Amazon Bedrock with no data retention

Simyl Flow — cons

  • − <strong>You can't sign up yet.</strong> As of October 2026 every CTA leads to 'Join Waitlist', the sign-in page accepts existing accounts only, and the parent company lists Flow as 'Private Preview' — while the pricing page still sells three plans and a 30-day trial. The vendor (Simyl AI, Inc., founded 2024, Toronto) is an unnamed 'small team of engineers' with no G2/Capterra listing, third-party reviews or press coverage
  • − Retro toolkit is thin on facilitator staples: no anonymous submission or private brainstorm, no drag-and-drop grouping, no presentation mode, no recurring or scheduled retros, no retro-board timer, and only four built-in formats plus a custom template against 50+ at retro-native tools — and almost no engagement layer (no icebreakers, GIFs, reactions, music or kudos wall), which makes it a poor fit for teams whose retro problem is participation rather than measurement
  • − The health score is computed from delivery signals, not from the team — the vendor is explicit that there are <em>"no surveys, just outcomes"</em>, so there is no survey-based health check, no sentiment analysis and no ROTI; there is no mood capture on the retro board either
  • − Enterprise claims are self-attested: 'SOC 2 aligned, not certified' and 'ISO 27001 aligned, not certified', inheriting AWS's certifications rather than holding its own; SSO/SAML sits behind a quote-only tier, there is no SCIM, and audit logs appear only as a sales-page offer rather than a plan feature
  • − Export is CSV plus PDF reports, and the PDF report download is Growth-tier only; there is no public REST API and no webhooks, and the MCP server is read-only, so nothing can push data back in programmatically
