Rx Assistant™ Lite
This inexpensive, handy, but critically important iPhone application will track all of the prescriptions, over-the-counter medications and vitamins that you take regularly and at infrequent intervals as well.
Recording much more than the name, the Rx Assistant™ will record dosages and even comments and doctors orders.
The built in medicinal history will record when and what you took and make it available by day and with time of administration also recorded.
