Fastoche does not endorse any specific hardware product. We don’t typically recommend cheaper store-brand devices, as you normally get what you pay for. Generally, any tablet/device with a browser will work. We do recommend using a modern browser such as Google Chrome or Mozilla Firefox.
You can have a mix of devices. If the device is for a toddler room for example a larger screen may be useful, as they will be using the device for journaling. However a smaller device for a school-age program might be sufficient.
As our system is completely web-based, local storage isn't something you need to worry about. We do not store anything on the devices themselves.
