I bought the app , becouse it's really well done ... unfortunately there are some question mark ? ¿ like this and mismatched formula here and there. Fix this problem and the app deserve a 5 star out of 5.
The app shell is listed as free but EACH module will cost money. $1.50 for ONE module is a bit much for someone who wants to use all of them. Uninstalled and not recommended to my college classmates.
Keep up the good work!!!
Should be more upfront About the cost Not a free app
Great and usefull!! Keep up the good work!!!
