Multiple sources are available to track historical times for individual swimmers.
SUNN's website - SUNN maintains a database of OnDeck Parent, an app available for iPhone, iPod, or iPad (and coming soon for Android). Use your SUNN account's login and password to connect.
Swim Connection - Swim Connection is a business independent of Pacific Swimming and USA Swimming. The company makes personalized meet results reports and extensive historical times data for Pacific meets available to their members, who pay a small fee for these services. The site benchmarks swimmers' performances to the Pacific Swimming time standards (PC-B, PC-A, JO, FRW, and PRT).
USA Swimming DECK PASS - The official source for historical times data for individual swimmers is the SWIMS database maintained by USA Swimming. There is no charge for accessing this database. Swimmers can create a Deck Pass account on the USA Swimming webiste. Deck pass allows USA Swimming members to track their times, earn digital patches for competing-automatically or awarded by coaches, check IMX scores, best time, recent meets and rankings; and connect with friends! Note that age group times on the USA Swimming web site are not benchmarked to Pacific Swimming time standards but to USA Swimming's National Age Group Motivational time standard which are slightly different. Also, the SWIMS database does not include times for 25-yard events for 8/under swimmers.
