Duo App Reviews

The "mobile" view does not send correct dimensions and therefore it does not receive mobile-optimized variant via media queries. Basically 2 iframes. LAME and not helpful at all!

It’s better to do one thing well than to do many things not so well.

Just checking this out recently... Not too revolutionary really is it? I dig the idea and see real value with showing concepts and development to clients. The clean look of the browser itself is really nice. I WILL be using it in an upcoming meeting. For a dev tool, I totally can imagine this as a Chrome Extension or similar - with more options. This baby should be on GITHUB for more dev as a browser or html/css/js tool. I am laying down a 3. If there was a 3+ available, that would be my score. As an MVP it is nice. As a real dev tool, it is lacking for me atm.

The app is good and I really like being able to see both views at the same time. Sometimes it runs a bit slow and requires I refresh several times until the page loads properly. The other issue I have with it is that I can’t change the user agent of the panes. Overall good stuff and definitely looking for updates to get more functionality and faster syncing

Some project I work on include websites that do not display the mobile version unless it recognizes the user agent as a mobile device/browser. With Safari already implementing a User Agent option in their development panel, I would like to see the same thing for this app.

I thought this would be a great piece of software to have as a web developer. I enter three different sites that I know have desktop and mobile versions. All three of them displayed the same desktop version in both broswer panes. Don’t waste your time (or your money) downloading.

I specifically wanted to use this for a wordpress blog that I am working on. As with many sites on the internet, once a mobile device is detected it will present an alternative stylesheet or a different theme for the website. The “mobile” webview doesn’t actually spoof the site into thinking it’s a mobile site. It just simply resizes the web view into a smaller view that is closer to what a mobile looks like. The mobile view can’t be stretched or put into well known screen sizes. On top of that, the app just crashed on me while writing this and the address bar doesn’t have simple things like history or a forward button. I’m going to hope that the core basic of actually allowing the mobile view to actually pretend to be a mobile device happens.

Awesome tool for working on responsive design. Facilitates being able to design for both mobile and desktop concurrently. Only thing bringing it down is the tendency for it not to want to quit and its lack of a way to resize left pane to try out different mobile screen sizes.

I was so intrigued by this, as a potentially useful tool to add to my responsive design workflow, that I bought it on impulse. I dont necessarily regret it, but there are some features Id love to see added to make it live up to my hopes. In its current form, I wonder if having two viewports glued together, with little else, competes with two different browser windows open side by side and loaded with various 3rd party extensions. - It would be great if there were preset sizes that could be quickly and easily set for each of the two viewports. For example, there are a number of "Resize Browser" extensions on the market that let you select from a drop down of preset sizes (and set custom sizes as well), and it will change the browser window to those dimensions. So, if there were presets like iPad portrait, iPad landscape, Nexus 7 portait etc. iPhone portrait seems to be the default for the mobile size, would be great to get other portrait presets and maybe even landscape too. - A bandwidth simulator for each viewport would be pretty cool as well, allowing you to preview the mobile side at 3G speed compared to desktop side at Broadband and such - Being able to export the current side-by-side screen views to a Bitmap (PNG) might also be a handy shortcut to having to screen grab manually Anyhow, I look forward to possible updates in the future, thanks for your consideration.

Read what the software does, and then if you choose to purchase it - don’t complain about what it doesn’t do. As a responsive site designer/developer this works wonderfully. It is very bare bones, but does exactly what it says without any issues. I can’t wait to see what this continues to develop into, but as for now I am very please.

I’ve been hesitant on using Duo for a month or two, but finally dove in. I can already see it creeping into my work flow and I’ve had it for about 10 minutes. It’s not the end all be all, but for designing with a mobile first strategy it will be a wonderful tool to help in my build process. Thanks Electric Pulp!

If you’re tired of “browserbating” while building websites then this is for you. Two different viewports in one app and synchronized clicking to boot. It’s pretty darn handy and I use it nearly every single day. Recommend. A++. Would buy again.

The first version was great, but the latest updates have cemented it as a key app in my workflow. The ability to quickly see what your site looks like at different sizes had made development more efficient by an order of magnitude. I used to dread making a site responsive, but now it’s a pleasure.

I love the simple user interface. And this really helps when previewing fully responsive sites; but if also let you set the user agent … that would make it complete, to me.

Just purchased and tried, here is what I found wrong: 1. The mobile view gives you a “frame” of your website, and not the “real view” of it on a real mobile device. In other words, on my mobile phone I can see my complete website page, reduced in size of course, fitting the full screen, whereas on this program I can see just a portion of the screen without size reduction which is not the real view you get on a mobile device. 2. There is no way to access any settings to target specific screen devices. I really expected that! For me, this app is useless and deceptive. To test my website for repsonsive design, I am going to use a real device.

Love the fact this has live reload support now. Duo has become a super handy tool to quickly test how things will look on multiple screensizes. It has a built in inspector, like Safari’s dev tools (which are prettier than Chrome’s IMO, but not as extendable… but I love how Safari can display minified CSS as expanded). Just a suggestion or wishlist item: I wish I could add it to my Alfred Workflow, not sure what would need to happen to add Duo to the "Open URL with” option. Maybe it is already doable and I am not accessing it correctly?

I build and do QA on a lot of web sites and I love this thing. It’s not a replacement for a real testing tool like BrowserStack or Sauce Labs, but it’s a great screening tool for use during development before you run tests on real testing tools like that. I was a little nervous when I bought it that it hasn’t been updated in a while, but it works fine in El Capitan. Supports full-screen mode. I agree with another reviewer that it would be even better if you could manually set the user agent string. With a list of common pre-sets. That would make it five stars. It’s still useful without that. There is a “resize pane” button with a drop-down selector that you can add with “customize toolbar”. That really should be included in the toolbar by default.
