It's called the Homeschool Helper, and it does everything! Literally. You can add all of your children separately and pre-plan the year by entering in lessons for each school subject, checking them off as you complete each one. You organize the subjects however you prefer - it's very intuitive but also allows enough freedom to organize the way that works best for you. You can keep track of attendance AND grades, it's wonderful. I love that it automatically tracks grades for me because ... although I have to teach math, I don't like it much :-) You can also keep track of the time used for schooling if needed.
I absolutely love this app. It created more work for me temporarily because I went back through the school year and entered in all the lessons and grades, but I am all caught up now :-) Homeschool Helper is awesome ... it was developed by a fellow homeschooler and is going to make my life so much easier! Yay for easy! If you are a homeschooling mama and looking for a fantastic way to organize your planning and grading, go check this out on Facebook!
