How it’s graded

Each check is built on how world-class product and growth leaders do this work, as they’ve described it on Lenny’s Podcast, and names the leader it comes from.

Limits the downside of being wrong
Does the call say how exposure is limited if it's wrong: what is watched after launch, the threshold that would pause or roll back, and which parts can't be undone?
Passes when Names the post-launch signal, a threshold or trigger, and the action, and flags anything irreversible (customer communications, pricing, migrations).
Karri SaarinenLenny’s Podcast
Judges the launch against a baseline set now
Does the call name the metric and the current baseline the launch will be judged against, and when the team will review the result to decide what's next?
Passes when Names the success metric, its baseline from the material, and a review point with what each result would lead to.

# Incidents during the 25% rollout (14 days)

- 2 reports of a note's edits being overwritten after a conflict, both on Android 11; engineering recovered both from backups. Root cause: an older Android storage API.
- 1 report of slow sync on iOS, not reproduced.

The launch review is Friday: roll offline sync out to 100%, or not. Marketing has a launch email booked for Monday to every user.

What a strong answer doesThe answer key the graders mark against

Checks each criterion per platform. iOS 17+, Android 14+ and Android 13 pass: crash-free sessions within 0.2 points of control (iOS -0.04, Android 14+ -0.06, Android 13 -0.09), sync-conflict tickets under 2 per 1,000, notes synced without error at least 99%. Android 12 and older fails three criteria: crash-free down 0.67 points against control, 4.9 conflict tickets per 1,000, 96.1% synced without error; and the two overwritten-note incidents were on Android 11, which breaks 'no data loss' (both recovered from backup, root cause an older storage API). Recommends go for iOS, Android 13 and newer, and no-go for Android 12 and older until the storage issue is fixed and re-tested; the Monday email should only go to users on supported versions, or wait. States what's monitored after launch and the threshold that would pause it.

Output

Recommendation: partial go

Ship offline sync to 100% on iOS 17+ and Android 14+. Do not ship it on Android 13 or Android 12 and older. Segment Monday's email so it doesn't promise the feature to users who won't have it.

Criteria check (25% rollout, 14 days)

Platform	1. Crash-free (≥ control −0.2)	2. Conflict tickets (<2/1,000)	3. Synced w/o error (≥99%)	4. No data loss	Verdict
iOS 17+	Go: −0.04	Go: 0.6	Go: 99.4%	Go: none (one slow-sync report, not reproduced)	Go
Android 14+	Go: −0.06	Go: 0.8	Go: 99.2%	Go: none	Go
Android 13	Go: −0.09	Go: 1.1, but over half the limit	No-go: 98.9%, misses by 0.1	Go: none reported	No-go for now
Android 12 and older	No-go: −0.67	No-go: 4.9, about 2.5× the limit	No-go: 96.1%	No-go: 2 overwrites on Android 11	No-go

Reasoning

iOS 17+ and Android 14+ pass every criterion with margin. Together they are about 80% of users. The iOS slow-sync report wasn't reproduced, so I'd watch it during the ramp but not block on it.

Android 13 misses one criterion by 0.1 points. That is small, but we agreed the criteria before seeing the data, and I don't want to bend them the first time a result is inconvenient. The trend also worries me. Sync success falls with each older Android tier (99.2 → 98.9 → 96.1), and conflict tickets rise (0.8 → 1.1 → 4.9). This looks like a gradient tied to the OS, not noise, so Android 13 sits on the slope. I'd hold it at its current exposure, find out why it's degrading, and re-measure. If it reaches 99% or better with conflicts still under 2, it can go.

Android 12 and older fails all four criteria, and it is not close. Crash-free sessions are 0.67 points below control, more than three times the allowed gap. Conflict tickets are about 2.5× the limit, and sync success is 3 points under the bar. The two data-loss incidents were edits overwritten after a conflict, on Android 11. Engineering recovered both from backups, but that doesn't make them acceptable. We only recovered them because users reported them, and silent overwrites may not have been reported. The root cause is an older Android storage API, so this is a structural problem and not a quick patch. I'd also disable offline sync for the users currently exposed on Android 11 and below until it's fixed. Data loss in a notes app is the failure users won't forgive.

The Monday email

An email to every user would promise a feature to roughly 20% of users (Android 13 and older, about 66,000 of 322,000) who won't have it. That means confusion, support tickets, and a bad first impression of the feature. My recommendation is:

Send Monday to iOS 17+ and Android 14+ users only, and only if the ramp over the weekend stays within the criteria. Marketing should confirm it can segment by platform and OS version.
Hold the email for Android 13 and older. Send it when each segment passes, or send a "coming to your device soon" version if marketing wants one.
Check the ramp Monday morning. If crash-free sessions or sync success slip on either approved platform, pause the email and the ramp.

Conditions and next steps

Android 12 and older: Engineering should scope a fix for the storage API issue, and we should re-test in a new, smaller cohort. I'd also like the data split into Android 12 versus 11 and below. The incidents were all on Android 11, so Android 12 itself may be fine, but this bucket can't tell us.
Android 13: Investigate the sync errors and re-measure in 1–2 weeks.
Data-loss monitoring: Add a check for overwrite after conflict, so we aren't relying on users to tell us.

Caveats

The data covers 14 days at 25%. The Android 13 miss is small enough that more data could move it either way.
Per-platform samples are decent (7,400 to 41,200 users), but two data-loss incidents is a tiny count. Treat it as a signal and not an estimate of the true rate.

Output

Recommendation for Friday

No-go for a blanket 100% launch. Approve a platform-gated launch for iOS 17+ and Android 14+, provided eligibility can be enforced reliably. Hold Android 13, stop expansion on Android 12 and older, and do not launch on untested platforms.

Replace Monday’s all-user email with a targeted announcement to eligible users only. If targeting or platform gating cannot be verified before send time, postpone the email.

Launch-criteria assessment

Crash-free changes below are percentage-point differences versus each platform’s control. The agreed limit is a decline of no more than 0.20 points.

Platform	Crash-free sessions	Conflict tickets: <2/1,000	Notes synced without error: ≥99%	No data loss incidents	Platform decision
iOS 17+	Go: 99.58%; −0.04 points	Go: 0.6	Go: 99.4%	Go: none reported	Go with conditions: passes all measured criteria; launch with eligibility gating and monitoring.
Android 14+	Go: 99.49%; −0.06 points	Go: 0.8	Go: 99.2%	Go: none reported	Go with conditions: passes all measured criteria; launch with eligibility gating and monitoring.
Android 13	Go: 99.31%; −0.09 points	Go: 1.1	No-go: 98.9%, below the 99% minimum	Go: none reported	No-go: sync reliability misses the agreed threshold.
Android 12 and older	No-go: 98.71%; −0.67 points	No-go: 4.9	No-go: 96.1%	No-go: two overwrite incidents on Android 11	No-go: fails all four criteria.
Web / iOS below 17, if supported	No-go: no evidence supplied	No-go: no evidence supplied	No-go: no evidence supplied	No-go: not established by supplied evidence	No-go pending validation: absence of rollout data is not a pass.

The recovered Android 11 edits still count as data-loss incidents for this launch gate: users’ edits were overwritten, and recovery required backups. Recovery mitigated the harm; it does not erase the incidents. Nor should Android 11’s identified root cause be used to clear the rest of the “Android 12 and older” cohort without separate evidence.

Conditions and next steps

Before expanding eligible cohorts: Engineering must verify OS-level gating, rollback controls, and platform-specific monitoring. Increase exposure in monitored steps toward 100% of eligible users, pausing if a launch criterion is breached. Investigate the unreproduced iOS slow-sync report; it is not currently evidence of a failed criterion.
Android 13: Diagnose the sync-error shortfall, ship a fix, and repeat validation against the same ≥99% threshold. Do not round 98.9% up or waive the criterion to meet the email date.
Android 12 and older: Halt expansion and safely disable affected functionality where feasible, preserving pending offline edits before any rollback. Fix the older-storage-API issue, test conflict recovery and data integrity, and rerun a controlled rollout demonstrating all four criteria.
Marketing and support: Clearly state supported versions and avoid implying universal availability. Give support a recovery and escalation playbook.

These results cover 14 days at 25% exposure, not proof of risk-free operation at full scale. The defensible decision is a constrained launch where the evidence passes—not a universal launch driven by Monday’s booking.

Offline sync launch recommendation

Recommendation: Go with conditions on Friday, for iOS 17+ and Android 14+ only. Hold Android 13. Turn the feature off for Android 12 and older. Do not send Monday's email to every user.

Two segments meet every criterion: iOS 17+ and Android 14+. Android 13 fails the sync-reliability bar. Android 12 and older fails three of four criteria and is where both data-loss incidents occurred. The criteria were agreed before the rollout, so I don't recommend relaxing them now that we have results.

Criteria check (25% rollout, 14 days)

Platform	1. Crash-free gap vs control (max 0.2 pts)	2. Conflict tickets (under 2 per 1,000)	3. Notes synced without error (≥99%)	4. No data loss	Decision
iOS 17+	✅ 0.04 pts (99.58 vs 99.62)	✅ 0.6	✅ 99.4%	✅ None. One slow-sync report, not reproduced	Go
Android 14+	✅ 0.06 pts (99.49 vs 99.55)	✅ 0.8	✅ 99.2%	✅ None reported	Go with conditions: engineering confirms the Android 11 storage-API bug can't occur on 14+
Android 13	✅ 0.09 pts (99.31 vs 99.40)	✅ 1.1	❌ 98.9%	✅ None reported	No-go: misses the agreed sync bar. Hold at 25% and fix
Android 12 and older	❌ 0.67 pts (98.71 vs 99.38)	❌ 4.9, about 16× control	❌ 96.1%	❌ 2 incidents (Android 11), recovered only from backups	No-go: turn off for current rollout users
Web	No data	No data	No data	No data	Not assessable: wasn't in the rollout

Why

iOS 17+ and Android 14+ are clean. Every metric clears its threshold with margin. The crash gaps are a fraction of the 0.2-point allowance. Conflict tickets are about 2–3× control, which is expected when people can now edit offline, and still well under the limit. The only condition on Android 14+ is confirmation that the overwrite bug is tied to the older storage API and can't occur there.

Android 13 is a near miss, but still a miss. It passes three criteria. Its 98.9% sync rate is just under the 99% bar. It is also trending worse than 14+ on every metric. Shipping it to 100% would mean overriding a criterion we agreed in advance. I'd rather fix the cause and re-review it in a follow-up launch.

Android 12 and older is unsafe. Roughly 1 in 25 notes fails to sync. The crash gap is more than three times the allowance. Two users had edits overwritten. We recovered those edits only because engineering pulled them from backups, which doesn't scale, and a user who never reports the problem simply loses their work. I recommend turning offline sync off now for the 7,400 users on this segment, not just excluding them from 100%.

Gaps in coverage: - Web has no rollout data at all. - iOS below 17 wasn't in the rollout, so it is untested.

Both should stay off until they have their own rollout.

Conditions for Friday's go

OS-version targeting. The feature flag can target by platform and OS version, so 100% means 100% of iOS 17+ and Android 14+ only. If it can't, the answer for Friday is no-go.
Engineering sign-off on Android 14+. Written confirmation that the overwrite root cause doesn't apply.
Off for Android 12 and older now. Done before or at launch, with a check that no user loses offline edits made while it was on.
Monitoring after launch. We watch crash-free sessions, conflict tickets and sync errors daily for two weeks. We roll back if any segment crosses a threshold.

Marketing email

An email to every user on Monday would promote offline sync to people who can't get it, including all web users, older iOS and Android 13 and below. For the oldest Android group, it would point them at the version we know loses data. My options, in order of preference:

Segment the email to iOS 17+ and Android 14+ users, if marketing can target by OS version.
Postpone the email until we can segment it, or until more platforms qualify.
Change the copy to say "now on iOS and newer Android, more platforms coming." This is a last resort, because it still lands with users who can't use the feature.

Next steps

Android 13: engineering investigates the sync-error rate, then we re-review.
Android 12 and older: fix the storage-API issue and run a fresh rollout before it's considered again.
Web and iOS below 17: start their own 25% rollouts against the same criteria.

Launch meetings reward optimism. A good call checks each agreed criterion, weighs a real risk against a real gain, and says exactly what would change the answer. A weak one rubber-stamps the launch or blocks it on noise.
