I noticed their apps are high in size compared to other apps, like for example their keyboard app size is 129 MB, which is a giant size compared to other android keyboards.
Grayjay also seems to be kind of giant, compared to bravenewpipe that supports a lot of services while still very low in size.
The only app in my opinion that has kind of reasonable size is their voice recognition, while it looks kind of ugly compared to Transcribro.
Is there is a reason for all of this?
So it's less than 100mb difference. You could go through both apps and see what files are taking up the extra space.
