itch.io

RPG Maker MV and MZ do allow mobile exports though the game would need a lot of edits to work on mobile especially since phones tend to have smaller screens (a large screen tablet or Chromebook would be no issue) than computers. Another issue is that Lawmage Academy runs at 1280x720 which works perfectly for most Windows laptops and 16:9 monitors (although some computers, such as Macs, use different aspect ratios), but phones often have wider screens like 19:9, Android tablets are typically 16:10, and the iPad is 4:3. RPG Maker MV can work on a device's different resolution but the game will be letterboxed or pillarboxed. It can be more complicated for games that rely on files or plugins that are intended for a specific resolution where they may not work well if the project is edited to use a different resolution.

I believe Apple and Google do require some hoops similar to Steam, although iOS would require a Mac while Android development can work on Mac, Windows, and Android. There is a thread about this, Exporting to Android (MV Android Client). On a similar note, it's possible to upload Android games through itch.io which can be ran on any Android device, but the device will need to allow non-Google Play apps. In theory, they could also work on an Android emulator, a Chromebook, or Windows 11 if support arrives.

I assume on a modern Apple or good name brand device (Google, Samsung, and OnePlus), the games could work well but I can't guarantee how it'll perform for older or low-spec devices especially cheap no-name devices from Amazon as their specs tend to be poor for an Android 10 device.
