Sync the flow of online video with the rhythm of your brain.


• Video stream controller for Safari
• Allows you to skip video ads
• Lets you customize the hotkeys
• Works on all your favorite websites
• Never collects any personal data


Upon launching the app, a button on the welcome screen will take you to the Extensions preferences pane in Safari. Click the checkbox next to the item called Dynamo and you're all set. A brief controls guide will appear.


While watching video in Safari, press these keys on your keyboard to control the playback:

[S] slows down any given scene
[D] sets the speed back to default
[F] makes the content flow faster
[E] lets you skip the adverts


All keyboard shortcuts are configurable. Click the Dynamo icon in your Safari toolbar and then choose the settings icon to edit the hotkeys.


Safari shows you a notice that says the extension can read personal information and browsing history. It's a general caution which shows up for every extension that changes the behavior of websites' elements. Dynamo does not read nor collect any personal data. We've deliberately designed this app so that we can't even encounter any. All Dynamo's processes run solely on your machine.


You may need to quit Safari in order to update Dynamo via Mac App Store. Closing the browser is not sufficient, quit Safari with command + Q or go to menu bar and choose Safari > Quit Safari.

Improved customization. - I like what it does. Clean, simple tool for exiting out of ads (for Safari users). My only complaint was that the app used to have too many pop-ups asking me to rate it and did not allow me to customize the keys used by the app. The developer has fixed both things. I now fully recommend this tool for exiting ads and speeding up videos.

Oh Hell No - I downloaded this app at the suggestion of another app that I really like by the same developer. Does anyone ever READ the privacy policy? This app gives the developer access to EVERYTHING you type -- passwords, credit card info, and every website you visit. I don't need Big Brother in my life. Dangerous app.
