Actually, as long as the game is made in Ren'py you can port it yourself using Joiplay and the Ren'py extension. Both are downloadable on Play Store and i think they are also on Apple Store. But i recommend searching for the latest patchs of those apps on Joiplay's Patreon, there are posts with the download links which are 100% free with no need of login or registration and the apps themselves are very easy to use.
