Ratings and Reviews
Good enough for me
When traveling I like to have my iPad with me as a backup in case my laptop crashes. I am also much more productive when working with two monitors than one. So being able to use my iPad as a secondary monitor is great! The screen resolution on my iPad is excellent when using it as a secondary monitor. Duet Display is a reliable option but with some caveats when connecting to a Windows 10 computer.
It is not quick to respond as a quality second monitor. Refresh rate/mouse lag ranges from slight to moderate. Mostly it is slight, but tends to get worse over the course of the day. It performs better after a reboot of my iPad and notebook. Once or twice a day Duet suddenly stops working, but the fix is simple. I open Duet on my notebook and hit “Quit app”. I then open Duet again and this fixes it every time.
If I could count on my notebook 100% then carrying a portable monitor would be a better solution. But, having my iPad as a backup gives me peace of mind that I will not be without a working computer if my notebook should fail for any reason. Duet Display is a serviceable option if you need a secondary monitor and prefer that secondary monitor to be an iPad capable of serving as your backup computer.
The app is good and the support team is divine
First time i write a review on App Store because i was amazed by the Duet support team.
The app worked very well with my iPad 4, which is so obsolete right now it can’t run any other app smoothly. The iPhone screen is quite small to be used as 2nd monitor so i passed on that.
So everything is fine as i expected, up until about recently i get stuck at “Launching Duet ...” screen. As a normal human being, i tried FAQs, Google to find answers but there is no working solution. So as a last resort i turned to support, got an automatic reply email and went to bed. The day after that, i found out that they replied literally 5 minutes after that with a few questions and a solution. That didn’t work right away but that just make me wished i asked them sooner. They kept providing me solutions after solutions, we exchanged emails for a week trying everything, they rotate 3 people in to help on my issue. The team is very polite, specifically pointed out every step along the way, never loose patient and always reply within the hour. After all it was a dumb mistake on my part, so everything is working normal again.
I have to say i worked with many support teams about many issues including Apple, Facebook, Google, Microsoft, Steam, and dozens of app and game developers. This is hands down the best experienced i had working with any team. The app maybe not the best but the team is perfect, and they keep improving with each update.
Unsupportive and Inconsistent
I would first like to say I’ve been using Duet in my workflow for over a year now with both an iPad Air 2 and 4. I really enjoy the functionality that Duet offers, however the entire setup process is to say the least inconsistent and buggy. I’m dexterous enough with technology to be able to remedy the problem after resetting connections and resetting computers, but for when there is free or cheaper options that come without these bugs, it’s hard to continue to recommend the app.
Another portion of my dissatisfaction is with the update rollouts. I use duet for PC connections, and finding the choppy and unrefined Windows program while updates for the program come out every few days or weeks is honestly saddening. The app on mobile devices also is unsupported, not having received an update in over 7 months and carrying the same bugs since the last update.
Other than the complaints stated above, I do want to say that the Duet Support Team is one of the best Support Teams out there, and a big reason I’m sharing this review is because I believe that Duet cares about their app and wants to refine it as much as possible. If any Duet Representatives read this, I hope this facilitates some updates and appearance changes for a better app and a better community experience. Thank you for providing this service and for your care to your customers.
(My 1 Star Review is to only get the attention of the Duet Crew)
