It probably would be good for kids. I downloaded this app using the QR code on the model solar system walk in Westcliffe, Colorado. According to the signs, this app was supposed to guide me through the virtual solar system model they have laid out along Westcliffe's main street. Very disappointing that this app requires an in-app purchase in order to use it. I wish the Westcliffe solar system model folks would have directed us to a free app that did not require an in-app purchase to use. Even a link to a simple PDF file describing our solar system would've been superior. Everything is monetized these days, even public education material, ugh! ### 1/5 — Not working *2023-03-08* I press play and nothing happens I don’t get any audio I can’t even scar the QR code. ## Frequently asked questions about X ### What is the learning methodology of X-Trails Pro?
