Show HN: I made a macOS app to let me draw on the screen while on video calls

This is my first macOS app that I launched yesterday. Really excited to share it with you all. The app is called Presentify and it lets you better explain yourself during presentations or while working from home via video calls, etc. Given that most of us are now working from home, I thought this might be helpful to some.<p>Here are the links:<p>* Website: <a href="https:&#x2F;&#x2F;presentify.compzets.com" rel="nofollow">https:&#x2F;&#x2F;presentify.compzets.com</a><p>* Demo: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;CTR1iAbGhjg" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;CTR1iAbGhjg</a><p>* Mac App Store: <a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;presentify&#x2F;id1507246666" rel="nofollow">https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;presentify&#x2F;id1507246666</a><p>Please, feel free to share your feedback. It would mean a lot to me.

This looks great and will come in very useful when presenting visual concepts (keep the audience focused).<p>One suggestion for future improvement would be auto shape snapping. I assume most will use this with a mouse which can result in squiggly, unsightly lines. A number of iOS note taking apps detect a similar shape and snap to straight lines or perfect circles. Hope that helps and thanks for the app.

Just bought it and it looks great! One feature that Slack&#x27;s video call has that would be nice to add is to have the possibility to auto-fade what you&#x27;ve drawn. Lets say if you haven&#x27;t drawn something within 5 sec, what you&#x27;ve drawn slowly fades away.

Great app, I just bought it and I will try it on the next WebEx conference calls :).<p>Some remarks:<p>- the &quot;Highlight cursor at app launch&quot; has a &quot;Start sdf sdfsdf&quot; tooltip<p>- I can not change the keyboard shortcuts (when I click on the button to configure them, nothing happens)<p>- the default keyboard shortcut &quot;Control + Option + A&quot; presented in the menu does not work on French keyboards and requires instead to push &quot;Control + Option + Q&quot;, which looks like a AZERTY &#x2F; QWERTY configuration issue?

Congrats on the launch!<p>Its hard for us with a very mixed tech stack to realise something like this. I&#x27;ve started thinking about using VNC to share Autodesk Sketchbook from my Surface Pro to do presentations and splicing it together with my webcam using OBS for meetings.<p>If anyone has done something similar I&#x27;d love to hear it, main workstation is linux.

Used to use something like this all the time in <i>compiz fusion</i> with a graphics tablet, before spinning the 3D desktop around with a key combination and firing up some completely different workload on the rear face of the cube. Ahh, those were the days. Seriously though, if you like writing on the screen and haven&#x27;t got a graphics tablet yet, get one. It&#x27;s like a revelation if you do most of anything that is mouse intensive, and your future arthritic hands will thank you for it.<p>Also check out <a href="https:&#x2F;&#x2F;github.com&#x2F;bk138&#x2F;gromit-mpx" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bk138&#x2F;gromit-mpx</a>

Wish you had posted this yesterday! I could have used it this morning. I bought a copy so I could use it for a presentation on Friday. Thank you for making it!<p>Suggestion: Make the diameter of the cursor highlight an option I can tweak.

Can I ask you a question regarding the &quot;auto starts on login&quot; feature? I have been working on that feature on an app I have but my app simply doesn&#x27;t want to start on login. I don&#x27;t even know how to troubleshoot it as nothing gets logged to the system.log using the console app. I used this tutorial but not sure why it won&#x27;t work:<p><a href="https:&#x2F;&#x2F;theswiftdev.com&#x2F;how-to-launch-a-macos-app-at-login&#x2F;" rel="nofollow">https:&#x2F;&#x2F;theswiftdev.com&#x2F;how-to-launch-a-macos-app-at-login&#x2F;</a><p>Did you face any issues too? Any thing I can use to troubleshoot?

Nice app, just bought it. One feature request - when using touchpad there should be some key to activate annotation&#x2F;drawing. It&#x27;s hard to draw on touchpad while pressing it.

This is really nice, buying it right now. Would like for an option to take a screenshot from this app itself, as opposed to Mac OS X&#x27;s native screenshot taker.<p>i.e. if I have a power point presentation open up that I&#x27;m &quot;drawing&quot; on top of, would like an option to screenshot&#x2F;record my screen, so I can save whatever annotations I have made.<p>Also would like to be able to add text boxes and type (as an addition).

As someone leading remote colleagues on UI&#x2F;UX work, this was an instant buy for me. Congratulations!

+ 10.12+ + AppKit<p>Suggestions: - screenshots are too small and on 10.14 video preview is missing - touchbar support - as someone suggested, if you demo sidecar + pencil you will get featured if your app is translated to 5-6 languages

I find myself wanting this every morning. How long ago did you start the app? It seems like the perfect time to launch it being that everyone is home.<p>I just bought it and will be using it tomorrow AM. Works great.

Not only is this great software, but the fact that it did not ask for overreaching permissions and did not try to connect to 5 different websites on the first run made it an instant win for me.

Hee hee...so I can draw devil horns and moustaches on my co-workers in boring meetings? Excellent!<p>&quot;helps you give better presentations by letting you annotate any screen, highlight your cursor, and more&quot;<p>Awww...

Nice presentation website. I&#x27;ve also just tried your app. I think it needs an exit button. It&#x27;s not obvious how to exit it (unless you know the shortcut) once you activate it.

Also check out <a href="https:&#x2F;&#x2F;screen.so&#x2F;" rel="nofollow">https:&#x2F;&#x2F;screen.so&#x2F;</a>. It&#x27;s free and works great. Was posted on HN a while ago.

This looks great, congrats.<p>Would love to see this on the iPad as well, know of a few corporate users looking for it. Happy to chat offline.

How does this fare with the Apple Pencil via Sidecar? Would definitely try this out if it works well.

Awesome work! Well worth the price for a nice, simple utility I feel like I will use everyday.

Any comparison notes with the similar app &quot;DemoPro - Screen Annotation&quot;?

What did you write it in, out of curiosity? Obj-C and Carbon?

Does anyone know an app like that for linux?

Thanks for this, well worth $3.61 CDN.

feature request: ability to write text on the screen
