I'm an indie developer focussed on just fun apps for now, but even if I get serious with productivity apps, they will be gamified :). So far I have built (1) an addictive platformer called "Munu Jump" which follows a day in the life of Munu a typical happy go lucky jumpy little girl. (2) Fire Swipe a one of a kind action-arcade game with sparks, colors and particle explosions. (3) Cube8 a 3D puzzle game. and (4) Vock which brings worlds most popular puzzle game tetris to Apple Watch.
