Yes this is a scam. If you read through the whole website, twitterfeed, bitcointalk thread and join their slack (which I am sure you did not) you can only conclude that this is a scam, because there is no app yet available in the app store.

Better invest in Tokencard or Monaco. They got some really nice fancy graphic mockups of their final product and some great partnership pictures where they are popping champagne bottles.

Thanks for giving such great arguments for your suspicion!
