TOPIC: A question about OBDII onboard display devices

I could use ideas and recommendations about which Scan gauge-type products to use. I'd like to get one of those accessory pod type displays that hooks into the OBDII port. I DON"T have a smart phone, please take pity on the very last person on the Planet who does not have this. I know, I'm weird.

While I was in hibernation in Rip Van Winkle's old bed, maybe it was the musty smell that made me have a halllucinegetic dream about watching certain OBDII data streams as I drive.

does anybody have any comments/ recommendations?
