I just got a 'push' update on my Android phone for Blispay... with this update it will now support Samsung Pay and Android Pay.
It stated there were some other minor improvements and bug fixes as well, and that they are listening to feedback for the app. I realize most app authors/companies say this, but since the audience for Blispay is tiny compared to most big companies, I feel it's likely they really are reading the customer feedback. 
I'm optimistic as well that they're actually taking feedback seriously. I've sent several feedback emails.
At this point my main suggestion would be to permit users to login with a PIN instead of requiring a full email address and password every time (similar to Discover).
Since they are already using two-factor auth. before displaying the account number this seems like a logical next step, but I'm sure they've already thought about this.
I'd like to see finger print log in.

For those with phones that can support it, even better! 
Fingerprint would be nice. I don't use the phone options because I worry too much about security, but that would be nice.

I agree that for those with phones that support it, adding fingerprint recognition would be fantastic!
As for security, they use two-factor authentication so it's about as secure as you can (reasonably) be without being obtrusive. It's actually the most secure banking site/app I currently use.
Even if you were to lose your phone it would be impossible to access your information without your password, and as soon as you report your phone lost even if the thief knows your Blispay password it would be useless.
