Try writing a sticky note on the bottle saying.... Sally had 1 teaspoon at 4:05pm

When I give my charges any medication (pain reliever, cold medicine) I always right it down or text mb and remind her when i leave for the day. She has no problem with me giving the medicine but she never seems to remember that I texted her what I gave them and at one time. In my one year review last week she mentioned that I need to be sure to tell her what time I last gave meds, as if I have never done that in the last year. My question is does anyone know of maybe an app that is compatable with both iphones and androids. Since she is so tech savvy I thought maybe an app would be good for us, we can both see when we gave meds
