You have to remember that this is a British app and we're probably not the best at things like asking for seats. As somebody who has been pregnant twice (and in the UK),I still can't really see what improvement this is over the baby on board badges. I don't think it is something I would have paid for - sometimes people just don't notice you certainly, but the chance of somebody having it installed in the same carriage seems pretty remote.
