Needs a UI update
I've been using this app for months to help keep sharp during my engineering class, but the UI sorely needs to be modernized for current iOS parity. Outside of that, app is great for learning Amtrak/NJT signals!

I have tried my best to silence this app. It is quite annoying to hear the announcements on every single flash card, for instance. Visiting preferences has the apparent ability to do this, but it turns mute off just after you turn it on!!
