A Money Suite
Practice, Learn, Manage
The apps are built to be used in that order — rehearse with virtual money, learn how the mechanics work, then track the real thing.
Practice
Rehearse banking and investing with virtual money. Nothing connects to a real institution, so there is nothing to lose.
Learn
Free guides, quizzes and calculators — no sign-up, no email, nothing to install to read them.
Manage
Track what you actually have and what you actually spend, entirely on your own device.
