Does anyone know who is running or owning the CoinCap app for iOS on the Apple AppStore?

I found a bug which let the app crashes and I want to inform the dev about it. The AppStore says it is ShapeShift AG. I contacted ShapeShift here on BTCT without any response. The AG appendix usually means that it is a German, Swiss or Austrian company similar to British Limited. Thus, I am not sure if shapeshift.io has really something to do with this app.
