Just downloaded this today. The spell factory set to level five still only has 4 as the max choice on the spell drop down menu. Also the training time for balloons, Wizards, healers, hogs and Valkyries are not correct. Balloons and wizards train in 8 mins not 10, healers are 14 mins not 15, hogs train in 2 mins not 5 and Valkyries train in 8 mins not 10. I didnt bother checking spells. Otherwise its nice to have a standalone calculator for troops.
