While sharing a screen, circle the point, zoom, and freeze on the picture itself. Step away from the desk and remote from the phone.
Public materials do not yet show how users complete this job today or what they replace.
The product targets friction in this job, but public user evidence does not yet show the cost, frequency, or consequence of leaving it unsolved.
Pointing while you talk has never been solved well in remote work, and heavier tools go unused. The trend is pulling the demo experience out of the meeting app. The entry is live circling in training, pitches, and online teaching. Available as a buyout.
It promises a simpler way to complete this job: While sharing a screen, circle the point, zoom, and freeze on the picture itself. Step away from the desk and remote from the phone. The exact adoption motive and repeat use are not yet verified.

for high-frequency micro-action tools, minimize the trigger cost — live in the menu bar, zero setup, float over what the user is already using, rather than making them migrate to a new interface. Users will not pay to "open another app," but they will pay to "not interrupt what I'm doing." free core + Pro buyout ($19.99/year or $29.99 lifetime) is worth copying — for high-frequency small tools, a lifetime buyout triggers "cheap enough to just try" far more easily than a monthly subscription.

The call and next move come first; the full read retains the evidence and counterevidence.
A live "explainer whiteboard" in the macOS menu bar: draw, zoom, highlight, freeze the frame, and record over whatever screen you are already sharing — plus a companion iPhone remote — without breaking your presentation flow.
Mustafa Cerit, an independent developer. On the App Store the app appears as "Screen Mark: Annotation & Draw," with a companion app, ScreenMark Remote (released 2026-06-09). Team size and company entity: not disclosed.
Read: a solo-maintained utility that takes the "point at something while you talk" high-frequency action and does it thoroughly — not a platform play. The judgment behind it is clear: remote collaboration never solved pointing well, and the problem was that tools were too heavy, not that there were too few features.
Local-first: recordings, screenshots, and annotations are saved to the Mac; nothing uploads, purchases go through the App Store. Multi-monitor and Stage Manager are supported.
"Pointing at the screen while you explain" used to be solved by compromise:
Sharing the screen and moving the mouse cursor — small, jittery, and the audience cannot tell which pixel you mean. Pre-drawing points into slides or screenshots — only covers what you anticipated; nothing for on-the-fly insights. Using the video conference's built-in annotation — one set per platform, minimal, and only works inside that meeting window; switch to an IDE, browser, or terminal and it stops. Or annotating a screenshot after the fact — but "annotate live" and "annotate afterward" are two completely different actions.
ScreenMark replaces the "live, cross-app, no-interruption" slice of those approaches: it floats as a layer above the screen, lets you draw over anything you are sharing, and adds back the physical freedom of walking around with a phone as your remote.
Freemium. Free tier covers the core annotation tools. Pro unlocks recording, live zoom, cursor highlight and flashlight, advanced annotation, custom break mode and shortcuts, and the phone remote. Pricing: $4.99/month, $19.99/year, or $29.99 lifetime, with a 7-day trial.
Read: a $30 buyout utility with restrained pricing, aimed at high-frequency teaching/presenting users rather than the mass market. The ceiling is a niche paying audience inside the Mac ecosystem, but the lifetime-license cash flow is clean and free of renewal pressure.
| Dimension | Call |
|---|---|
| Founder-product fit | A solo developer's single-point tool that fits the teaching/demo scene tightly, as if he uses it daily himself |
| Product insight | Nailed the "point while you talk" action and understood lighter-is-better; the phone remote is the smart differentiator |
| Execution quality | Menu-bar resident, cross-app overlay, recording, multi-monitor — built like a mature product |
| Timing | Remote work and online teaching are the new baseline; the presentation-pain point keeps getting confirmed |
This is the "do a light tool properly" route, not the "build a platform" route.
Everyone has the "point at something while explaining" pain in remote work, and most solutions die from being too heavy: full whiteboard apps require pre-meeting setup, a UI to learn, and content to migrate. ScreenMark's tradeoff is floating over the existing screen, zero preparation, one-action trigger — it does not replace anything you are already sharing, it just adds a transparent, drawable, pointable layer.
The transferable rule: a light tool's moat is habit, not features. Once a teacher gets used to "sketch it right there," they never go back to pre-drawing. The phone remote adds back the physical freedom of "walking the room without touching the keyboard," turning the tool from a desktop app into a teaching instrument.
Two limits: it is macOS-bound and requires macOS 15 / M1 or newer, which shuts out a large share of Intel Mac users (the official site and the App Store listing disagree on requirements — worth verifying on your own machine); and there is no exclusive feature moat — an open-source project or an Apple-native upgrade could cover the same ground. The moat is mostly habit and the remote experience.
① Whether App Store ratings and review count accumulate over three months — for utility apps, reviews are the hard signal ② Whether anyone makes it part of a "teaching/livestreaming default kit" in shared workflows — habit products spread by word of mouth ③ Whether the buyout price adjusts or the platform expands (e.g., an iPad build) — that sets the market ceiling
Product logic: for high-frequency micro-action tools, minimize the trigger cost — live in the menu bar, zero setup, float over what the user is already using, rather than making them migrate to a new interface. Users will not pay to "open another app," but they will pay to "not interrupt what I'm doing."
Pricing structure: free core + Pro buyout ($19.99/year or $29.99 lifetime) is worth copying — for high-frequency small tools, a lifetime buyout triggers "cheap enough to just try" far more easily than a monthly subscription.
Worth watching. A single point done well, restrained pricing, local-first — a good sample of an independent developer building a light tool. But it is macOS-bound with no exclusive moat, so the ceiling is limited. Its value is the "how to turn a high-frequency micro-action into a habit product" thinking, more than the market size.
