My Financial Freedom Tracker is built by a developer on his own FIRE journey, and the calculators run on the same engines as the app. Keeping them free, with no sign-up, is the best demo of what the full app can do — if a tool helps you, you might stick around for budgeting, net worth tracking, and the complete FIRE planner.
