Fast 50 was designed to keep track of how recently you have contacted your most important contacts. It has a simple color-coded layout to easily display which contacts you should contact in the near future. A customizable maximum time between the current date and the last contacted time can be set to your desired length. The idea behind this app was the system my dad uses to manage his top contacts. This strategy, used by many successful business people, is intended to help your most important contacts remember you as well as to make them feel remembered and important. Although designed for business people, this app may also be used for people who wish to keep in contact with friends and family from an old school, camp or job while away or somewhere like college.

Now add multiple lists with individual target times for each list. Individual contacts can now also have separate target times within various lists.

The only difference between the free and paid versions are the iAds in the free version (in the future features may be disabled in the free version or new features may not be added).
