How much does NFP cost?
NFP for Palm OS is freeware. I have committed to maintaining the software as freeware. I wrote the software primarily for my own use, but I thought others would benefit from its availability. Low cost is one of the inherent benefits of the NFP method. Outside of the small one-time cost of a thermometer, there are no additional weekly or monthly costs associated with the NFP method. Additional information on learning the techniques associated with the method can be obtained for free from your local library. See Links and Reviews for more information. However, there is a cost to developing the software, from compilers to testing the software on various devices. While one should feel no obligation to pay anything because I want the program distributed as freeware, I am accepting donations via PayPal below. All donations will be put toward the cost of development and testing this NFP program.
