    Full-screen countdown with a three-ring hours/minutes/seconds display, background presets, system clock overlay and audio alerts.
  • iPhone Remote Control
    A free companion iPhone app turns your phone into a remote for the Mac overlay: cursor highlight, flashlight, drawing, zoom and slide navigation for Keynote, PowerPoint and Preview. Pairs over local Wi-Fi with a four-digit code — no account, no cables.

  • Developer-Friendly Hosting
    Opalstack is designed with developers in mind, offering SSH access, Git integration, and support for multiple programming languages and frameworks including Python, Node.js, Ruby, and PHP, giving developers granular control over their hosting environment.
  • Affordable Pricing
    Opalstack offers competitive pricing for shared and managed hosting plans, making it an accessible option for small businesses, freelancers, and individual developers who need robust features without enterprise-level costs.
  • Modern Control Panel
    Opalstack provides a clean, modern, and intuitive web-based dashboard for managing sites, applications, databases, and email accounts, which is a significant improvement over older-style hosting control panels like cPanel.
  • Strong Support for Multiple Applications
    The platform supports a wide variety of application types including WordPress, Django, Flask, Express, static sites, and more, allowing users to host diverse projects on a single account with easy deployment.
  • Reliable Infrastructure and Support
    Opalstack is built by former WebFaction team members, bringing experienced hosting expertise. They offer responsive customer support and a reputation for stable, well-managed server infrastructure with good uptime.

Possible disadvantages

  • Smaller Community and Ecosystem
    Compared to major hosting providers like DigitalOcean, AWS, or even shared hosts like SiteGround, Opalstack has a smaller user base, which means fewer community tutorials, third-party guides, and forum discussions available for troubleshooting.
  • Limited Scalability Options
    Opalstack is primarily a shared hosting provider, which means it may not be the best choice for high-traffic applications or projects that require rapid, on-demand scaling of resources like CPU, RAM, or storage.
  • Not Ideal for Beginners
    While developer-friendly, Opalstack's approach can be intimidating for non-technical users. Setting up applications often requires familiarity with the command line and server configuration, which may not suit those looking for simple one-click solutions.
  • Limited Data Center Locations
    Opalstack offers a relatively small number of data center locations compared to major cloud providers, which may result in higher latency for users targeting audiences in regions not well-served by the available server locations.
  • Fewer Managed Services and Add-ons
    Unlike larger hosting platforms, Opalstack lacks a wide range of managed add-on services such as built-in CDN integration, managed backups with granular restore options, or one-click SSL management that more mainstream providers offer out of the box.

Questions & Answers

As answered by people managing ScreenMark and Opalstack.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.
