It never worked in landscape mode. I like this app. It's a great starting place, but its claims to be "optimized for tablets" are unfortunately untrue. It only worked in portrait mode on my Samsung Galaxy Note 10.0.
Suckz Doesn't even start on my samsung tablet SUCKS!
Nice This app help me to improve the typing speed.
