As answered by people managing Intercom and ScreenMark.
ScreenMark's answer:
Two things.
First, the iPhone remote. ScreenMark ships a free companion app that turns your phone into a physical remote for the Mac overlay — cursor highlight, flashlight, drawing, zoom, and slide navigation through Keynote, PowerPoint and Preview. It pairs peer-to-peer over your local network with a four-digit confirmation, no account and no cables. Every other screen annotation tool on the Mac assumes you are sitting at the keyboard. This one follows you when you walk to the screen.
Second, it covers the whole session rather than one slice of it. Annotation, live zoom, freeze frame, snip, whiteboard and blackboard, a full-screen break timer, and MP4 recording with system audio and microphone all live behind a single menu bar icon. Competing tools each own one of those jobs, so people end up stacking three utilities to run one presentation.
It is also local-first by design: no account, no servers, no analytics, nothing uploaded, fully sandboxed.
ScreenMark's answer:
The direct alternatives on macOS are Presentify, Scribbble, Presenter Pointer, Annotate, DemoPro and IPEVO Annotator; on Windows, Epic Pen and ZoomIt.
Against all of them ScreenMark adds two capabilities none of them have: control from your iPhone, and built-in screen recording with system audio and microphone mixed live, annotations included. If you present remotely or record training material, that removes a second app from your workflow.
It is also the only one in the category localised into 20 languages. The people who buy annotation tools — teachers, lecturers and trainers — are overwhelmingly outside the English-speaking world, and every significant competitor ships English-only.
On price: Pro is $29.99 once, or $19.99 a year. The category leader is $14.99 one-time for a smaller feature set, and the tools that do offer recording are typically subscription-only at a much higher tier. There is a genuinely usable free tier, and a 7-day trial on the subscriptions.
ScreenMark's answer:
Teachers, lecturers and corporate trainers first — anyone who explains something on a screen to a room or a call, repeatedly, as part of their job. They are the group that needs zoom, whiteboard, break timer and recording in one place, and they are the reason the app is localised into 20 languages.
Second are software people running demos: sales engineers, product managers and developers walking a client or a team through an interface. For them the draw-and-zoom-over-any-app behaviour matters more than the teaching features.
Third are content creators recording tutorials, who use the annotation and recording together.
Across all three the common thread is that the work happens live, in front of other people, and switching apps mid-explanation breaks the room. That constraint shaped the whole product — one menu bar icon, keyboard shortcuts for everything, and a phone remote for when you are not at the desk.
ScreenMark's answer:
The thing that kept me building was realising the problem was not "I need a pen tool." Presenting on a Mac, I kept doing the same thing: talking about something on screen while waving the cursor at it and hoping people were looking in the right place. Plenty of tools solve the drawing. None of them solved the fact that the person presenting is not sitting still.
That is why the iPhone remote exists, and it is the feature I now use most. Once you can trigger highlight, zoom and drawing from your hand, you can walk to the screen and still drive it.
The rest followed from the same observation. Freeze frame, whiteboard, break timer and recording are not separate utilities — they are the parts of running a session. So they all went behind one menu bar icon.
The macOS app shipped in April 2026, the iPhone companion in June, and it has been localised into 20 languages since.
ScreenMark's answer:
Built entirely with native Apple frameworks and Swift — no third-party SDKs or dependencies anywhere in the project.
The macOS app is SwiftUI and AppKit, using ScreenCaptureKit for everything that touches the screen: live zoom, freeze frame, snip and recording. Purchases run through StoreKit. The iPhone companion is SwiftUI, and the two apps connect directly to each other over the local network — peer-to-peer, with no server in between, so nothing leaves the two devices.
Universal binary for Apple Silicon and Intel, fully sandboxed, distributed through the Mac App Store.
