Tablo App on Different Devices

I was curious why the Legacy app looks different on each platform I am using a Roku Ultra and I have a Tivo 4 Stream and a Fire stick 4 K and the app is different on each platform. One would think it would be the same on all the platforms. For me the app works better on the Android devices than the Roku and has more features.

The developers are using the native tools of each platform, so they don’t all work the same way.

The fourth gen apps appear to be more consistent, but there are still differences.

Thanks. It just seems like Tablo would keep it the same for all the platforms but what would the world be like without change

I have the Tablo HDMI. The Roku is the oddball interface. The native, Fire TV, and Google TV apps are more or less identical.
