CovertLunch vs LookBusy: Chrome Extension vs iOS App (2026)
LookBusy is a $0.99 iOS app for manual fake events. CovertLunch is a Chrome extension with randomization and anti-pattern logic. Side-by-side comparison.
Short answer: LookBusy and CovertLunch are the only two products on the market doing calendar camouflage. LookBusy is iOS-only with manual event creation. CovertLunch is a Chrome extension and cloud service with a randomization engine, anti-pattern logic, and Microsoft 365 support.
If you only need a one-off fake meeting on your phone, LookBusy at $0.99 is fine. If you need consistent lunch protection that survives long-term pattern recognition, the workflow is meaningfully different.

What LookBusy Does
LookBusy is an iOS app priced at $0.99. You manually create a fake meeting on your phone, give it a title, and it appears on your iOS calendar. The app is local-only and does not transmit data.
It works as a single-event tool for the moment when you need to be unavailable. It is not designed for daily lunch protection.
Where CovertLunch Differs
Automation. CovertLunch writes one to three events into your lunch window each morning automatically. You configure your lunch window once. The extension handles the rest.
Randomization. The Chrome extension draws titles from a curated pool of realistic meeting names (Vendor Sync, Pipeline Review, 1:1 — Product Brief, etc.), varies durations between 25 and 60 minutes, and shifts start times within your configured window.
Anti-pattern logic. The engine tracks which titles, durations, and times have been used recently and avoids repeating them in detectable patterns. No two consecutive days have the same set.
Microsoft 365. LookBusy is iOS-only and works with iOS Calendar, which often syncs with iCloud or Microsoft Exchange but does not directly write to a Microsoft 365 calendar API. CovertLunch's cloud version supports Microsoft 365 natively.
Platform. LookBusy is for iOS users who interact with their calendar primarily on their phone. CovertLunch is for desktop users on Chrome (the extension) or any user who wants the cloud service via calendar feed or direct API.
Where LookBusy Wins
Lowest price. $0.99 is hard to beat.
Mobile-first. If you primarily check and edit your calendar on iOS, LookBusy fits that workflow better than a Chrome extension.
Single-purpose simplicity. If you only need one fake meeting occasionally and not a daily protection system, LookBusy is exactly enough.
When to Use Each
- LookBusy: One-off availability blocks on iOS. Occasional use.
- CovertLunch: Daily lunch protection on a desktop-driven workflow. Microsoft 365 users. Anyone who wants the camouflage to be automatic.
Can You Use Both?
Sure. LookBusy on your phone for in-the-moment availability blocking, CovertLunch on your desktop for systematic lunch protection. They do not conflict.
The Math: Why Daily Randomization Matters at Scale
The case for randomization gets stronger as company size grows.
At a 10-person company, your three closest collaborators see your calendar every week. They notice the Lunch block. They respect it because they like you. Manual single-event tools like LookBusy are perfectly adequate.
At a 200-person company, dozens of people scan your calendar weekly. Half of them are scheduling assistants doing it on behalf of someone else. The pattern "Lunch every weekday 12-1" gets cached. Within two weeks the schedulers know exactly which days you tend to be flexible on (Mondays, because of the Friday catch-up), and that is when the override happens.
A varied schedule defeats this. If the block on Monday is a 35-minute Vendor Sync at 11:45, and Tuesday is a 50-minute 1:1 — Product Brief at 12:15, and Wednesday is a 30-minute Pipeline Review at 12:30, there is no pattern to cache. The schedulers default to assuming you are unavailable in that window and route around it the way they would around any other meeting block.
LookBusy does not vary titles, durations, or start times. That is fine at 10 people. It stops being fine at 200.
What About iOS Users Who Want CovertLunch?
The CovertLunch Chrome extension is Chrome-only. iOS users have three paths today.
Option A: Chrome on iOS. Chrome on iOS does not support extensions (this is an iOS sandbox restriction, not a Chrome limitation). Wait for the CovertLunch cloud version + companion app, currently on the 2026 roadmap.
Option B: Cloud service via the web dashboard. The CovertLunch cloud service (/service) runs server-side and writes to your calendar via OAuth. Configure it once from any browser, including mobile Safari. The events then appear on your iOS Calendar via the standard Google or Microsoft sync.
Option C: LookBusy for one-off blocks, CovertLunch cloud for recurring. As described above — they cover different needs.
iOS Shortcuts as a Third Option (Free)
If LookBusy's $0.99 is not the bottleneck, the cheaper option is to build the same thing yourself with iOS Shortcuts.
The recipe:
- Open the Shortcuts app on iOS.
- Create a new shortcut with the Add New Event action.
- Configure title, start time, end time, and calendar.
- Schedule the shortcut to run daily at 7:00 AM via a Personal Automation.
This gives you a free daily fake event, but without randomization. You will write one title that runs every day forever, which has the same pattern-recognition problem as a "Lunch" block. Worth knowing exists; not actually a better solution.

Frequently Asked Questions
Is LookBusy still being updated?
LookBusy has been on the iOS App Store with light update activity. As of 2026 it remains the only iOS-native option for this category.
Why doesn't LookBusy randomize titles?
LookBusy was designed as a single-event tool, not a daily protection system. Randomization is a feature of the recurring-protection use case.
Does CovertLunch have a mobile app?
Not yet. The roadmap includes a mobile companion app for cloud subscribers. The Chrome extension works on any browser that runs Chrome extensions (Chrome, Edge, Brave, Arc, Opera).
Can CovertLunch generate one-off fake meetings like LookBusy?
The Chrome extension popup includes a "Generate Now" button for ad-hoc generation. The cloud version supports custom dates.
Is the CovertLunch engine open?
The randomization logic in the Chrome extension is auditable from the Chrome Web Store package. The title pool is also editable from the extension popup.
Does LookBusy work on iPad?
Yes, the iOS app runs on iPad. The interaction model is the same: manual single-event creation.
Will CovertLunch ship an iOS app?
A companion iOS app for cloud subscribers is on the 2026 roadmap. It is a thin client that mirrors the web dashboard; the randomization engine stays server-side. No date yet — the priority order is Microsoft 365 GA, then mobile.
Does either tool transmit my calendar data anywhere?
LookBusy stores events on-device in your iOS Calendar; no transmission described in their privacy policy. The CovertLunch Chrome extension is similarly local-only — write-only OAuth, no server. The CovertLunch cloud version transmits the events it writes (necessary to write them) but uses a write-only scope and stores nothing about meetings it did not create itself.
