The app is called ING Retire, and is available for iPhone, iPod Touch, iPad and Android devices.
Depending on their particular retirement plan, participants can view current balances and balance history, balances by asset class and fund, personal rate of return, fund performance and contribution history. Participants may also have balance and transactional capability, which includes the ability to change contribution rates, make a fund transfer, reallocate current balances and change investment elections for future contributions.
