A retrospective tool for teams that want to get better
Capture thoughts throughout the sprint. Reflect together. Turn insights into action.
01 During the sprint
A thought takes ten seconds to write on Tuesday and is gone by Friday. Muni keeps a quiet place open all sprint — on your phone, between tasks. If the signal drops, it waits and sends when you’re back, and tells you plainly when a thought has reached the sprint.
02 Sealed
Not the facilitator, not your manager. Until collection closes, the only thoughts you can see are your own — and you can still change them.
03 Opening the sprint
Everything is revealed at once, shuffled. Shared screens never show who wrote a thought, or anything that ties one person’s thoughts together.
04 Discover
The facilitator gathers them into themes by hand. The original words are never replaced. Votes are private until the round closes.
05 The retro
The shared screen puts what people wrote at the centre — not a summary of it. Voices are invited one at a time, and the room moves at the pace of the conversation.

PR review turnaround
What would make a first review arrive within a day without making reviews shallower?
PRs sat waiting for review for two or three days. I stopped opening small PRs because it wasn’t worth the wait.
Reviews: I actually liked that reviews were slower this sprint — the comments were more thoughtful than the usual rubber stamp.
The retro experiment (daily review window) helped: my two PRs were reviewed the same day.
The daily review window didn’t change much for me — reviews still waited until someone had slack.
Try a ‘review buddy’ pairing for the sprint so every PR has a named first reviewer.
Invitations follow who is present and ready — never who wrote what. Passing is one tap, and it’s immediate.
Follow the stage, vote privately, add context to a topic, step out of the rotation, or say “I’ll own this” to an experiment.
Opposing views sit side by side in their own words. Nothing is averaged into a paragraph.
06 Decide
One to three concrete changes, each with an owner who says yes, a sign that it helped, and a date to revisit.
TakeawayReviews wait because nobody owns the first look.
Experiment
For the next sprint, reserve a 15-minute daily review window right after standup.
07 Next sprint
Reserve a 15-minute daily review window right after standup.
“Most PRs got a same-day first pass. Bigger PRs still waited.”
Write the sprint goal as one sentence at the end of planning and pin it.
“We wrote it, but planning overran and nobody looked at it again.”
Honest outcomes, including the ones that didn’t work. That’s the difference between a team that meets and a team that learns.
Privacy
Muni uses your account information and contributions to provide and protect the service. We don’t sell your personal data, use your contributions for advertising, or use them to train AI models.
Until the facilitator closes collection, nobody on your team can read what you wrote — the facilitator included. Then the sprint sees every thought at once, in random order, without names.
New sprints are encrypted in the browser before anything reaches Muni’s servers, and the servers don’t hold the keys to read them. Muni still knows who wrote each thought and when, sprints from before encryption aren’t covered, and your wording can still give you away.
You sign in with a passkey — your fingerprint, face or screen lock. It’s the only way in: there’s no password or email to steal.
The app has no analytics, ad trackers or session recording, and no thought is sent to an AI service.
Open source
Muni’s source code is public under the Apache 2.0 license. Read how a thought is sealed on your device, check what the server keeps, or run your own copy on Cloudflare.
The whole encryption design is written down, so anyone can check it. If you spot a problem, tell us privately.
