IF you own a computer with an older version of iTunes already on it, try using that version as an old 2010, iPad 1 does not need the latest iTunes version. If you need apps for that iPad, if you have a computer with an older version of iTunes (version 12.6.4 or earlier ), you can try downloading the recent app/s, by accessing the iOS App Store, through iTunes, and then, download the recent version of the app/s you like to use on your iPad, to iTunes on your computer, FIRST. Tap the OK button just below the prompt to start the downloading of the older app version to your iPad. Would you like to download this version now.
Then, back on your iPad, you can try to download the latest app from the iOS App Store and if the developer/s has/have left an older, compatible version of their app/s on Apple's app servers, then you will receive a small window pop-up prompt that states that there is an older version of the app that is compatible with your device. If you have a newer iDevice, install the newer version of the app to your newer iDevice first. It was underpowered with only 256 MBs of RAM and NO cameras for image/video shooting or FaceTime calling. The 1st generation iPad was, more or less, an early adopter model iPad. IOS 5.1.1 is the highest iOS the 2010, 1st generation iPad can go.
