As another poster said, purchase the app from another Apple device, then do cloud download to iPad 1. Installed iTunes from Microsoft store on my gaming laptop. Login to iTunes. Downloaded from the website specified by the app. Disconnect and reconnect USB A from laptop if iPad 1 not detected by iTunes. Adjust monitors (iPad was primary after software installation , had to set laptop screen back to primary). Works perfectly displaying discord while I’m gaming on laptop monitor. **Developer response:** Thank you for using our product. If you have any questions while using the product, please contact us through the website. thank you (Inquiry: http://www.easynlight.com/en/contacttwomon) ### 5/5 — Working with iPad 1 in 2021 *2021-10-02, version 1.2.29* Ok, to purchase for iPad 1, purchase from newer iOS device and then access from purchased on iPad 1 App Store. To lower latency, just use 800x600 resolution. Looks more appropriate anyways. Not bad, very little lag. Going to find out if I can use yousician with the lag, perhaps I can just delay the audio to match. Anyways I have my Casio Privia digital piano hooked up to the Mac mini with iPad 1 as my “ultra thin monitor” and am enjoying all my vst instruments through headphones. And access to my DAWS. Mac is zip tied to piano stand, pretty tucked away. Thanks TwoMon. ### 1/5 — It doesn’t work *2021-03-01, version 1.2.29* Plz refund! ### 5/5 — I had a new iPad and now an old one, both work *2020-04-17, version 1.2.29* This is a great app for versatility as well as because it WORKS. I have favorite wifi apps... but only this one works all the time.. you DO need hdmi to set it up... i mean you have to see you of screen ... after that, I am able to use it as my main monitor or as an extension. Love it **Developer response:** Thank you for using our product and giving us a good review. If you have a problem while using, please contact us through a homepage. http://www.easynlight.com/en/contacttwomon/ Thanks! ### 1/5 — Stopped working, terrible service prices *2019-05-01, version 1.2.29* Great while it worked. Can’t connect, and they make you jump through confusing hoops just to contact them for help. ### 1/5 — Not working *2019-03-10, version 1.2.29* Everything is installed including iTunes. Will not connect to tablet and keeps prompting to install iTunes. ### 4/5 — Wonderful *2019-02-10, version 1.2.29* I had purchased the bundle for usb pc but it didn’t work like expected. I then found this app which is what I needed. This app is great! Waiting to hear from the developers if I can get a refund for my previous choice and buy this instead. Great work! ### 4/5 — Nice app, with a few kinks *2019-02-02, version 1.2.29* This app works as described by extended your computer display on a second monitor. I used this to add an additional monitor while traveling using my laptop and iPad Pro 12.9 display. The dimensions of the screen as others have mentioned you may have to adjust, but it works well with added benefit of touch screen from the iPad. Only glitch or kink is when connected I can not print documents. Not a major issue but enough of a hassle that I’ve decided to test out a portable monitor for at home and use this app primarily while traveling. ### 1/5 — Does Not Work *2018-11-14, version 1.2.29* Does not work with Windows 7. ### 5/5 — Nice app! *2018-07-28, version 1.2.23* Have been using TwoMon for a while, with Windows 7 and a 2012 iPad, and currently with an iPap Air 2 and Windows 10. Very happy with it. Works great. Sometimes it can be laggy, but that has been usually a conflict with some other app on the PC side of things. Most annoying thing is having to install iTunes on the PC to connect the iPad (I don’t use iTunes), but there are drivers you can install so the iPad is recognized by Windows without having to install the entire iTunes app (and yes, this is an Apple thing, not MS). Thumbs up TwoMon! ## Frequently asked questions about TwomonUSB ### What does TwomonUSB do? TwomonUSB allows you to use your iPad or iPhone as a secondary monitor for your Windows PC or Mac.
