Great idea but missing a few things

I love the ability to practice dual n-back on the road, so thanks for making this app.

I have a few suggestions for making it more practical to use. Firstly, dual n-back is by its nature taxing on the brain. Currently the app displays a brief splash screen and then throws you directly into the next level without any warning. It would be great to have a "start" button so users will be able to actively choose when to start another round. Secondly, please add pause functionality. When youre on the go with your mobile device, things come up - please let us pause our round and resume or restart.

All in all this is a decent way to practice dual n-back tests and when these additions are implemented, it will be great!
