Each brain processes information at a distinct pace, yet every video on the internet is being streamed at default speed. So we’ve built Dynamo, a powerful Safari Extension that lets you control video playback on every website you visit. Now you can sync any online video with the rhythm of your mind. Let’s tweak the flow of content and get rid of commercials you don’t want to see. You’re going to recoup mountains of time!

Could Be Better, and Easily!

I love this app, most sincerely worth every penny. The problem is not with the app, but with the developer. At bout every 10th skip (E) it requires you to rate the app. You can choose to ignore, but it wont skip. What's the point? Apple is not going to register the same user ID giving your app 5 stars over and over again. I gave you five stars and an excellent review, so why persist? Either develop another app and label it pro, or raise your pricing. It's more anoying that you just created another step in clicking skip. Now I click E your rating pop-up appears and wether I rate or close by that time frame the skip button has illuminated.

Needs custom option.

I like what it does. Clean, simple tool for exiting out of ads (for Safari users). But there are two huge problems. On a regular basis this app creates a pop-up asking to rate the app. There should be a way to stop this from appearing after the first time you see it. Also, the app monopolizes the 'F' key which is obviously used by lots of video sites as a full-screen shortcut. We need an option to customize which buttons are used by the app. Until these things are fixed, I can only give it 3 stars.

Great app! Need come customization

Just bought the app and it's working very well in Safari. No glitches or bugs on macOS 18E226 / Safari Version 12.1.

My only complaint is that it overrides the "F" key which is used by many websites to put a video in fullscreen. Can I map it to something else? or can we disable certain hotkeys from Dynamo? Thanks for this app!
