It’s strange that a company (agency) asks for funding, since it’s a commercial business. I’m sure they were paid by Athom and the brand to build and maintain the app, otherwise they wouldn’t have even built it in the first place, so it’s strange to ask for more money from the app users as well.
And like I said earlier: if they wanted to add support for all devices but don’t have the money to buy them, then they could have just kept the app open source and let other devs add support for them.
