I tried various cheap tablets but in the end went back to an iPad as it had the best combination of size and clarity.
Software-wise I use PiaScore (
https://apps.apple.com/us/app/piascore-hd/id406141702). Basically you load the score as PDFs and can them arrange as setlists, it also allows you to annotate the scores if you need to.
You can turn the page by blinking at it but I use a foot pedal. I settled on the Donner one, relatively cheap but does the job, after a couple of failed experiments. The iRig Blueturn lasted less than a year before it failed and an eBay special with 2 foot switches like on a guitar effects pedal I sold because the click was too loud. Depending where you use it that may not be an issue - I'm not of a standard to play in public - but the noise was annoying at home. Having said that I suffer for my art so I see no reason why others shouldn't too.
