FIRE: Retirement Calculator app iconFIRE

Everything unlocked, once

The FIRE number and countdown are free forever. Pro adds the deeper planning tools — as a single one-time purchase, not a subscription.

Free is genuinely useful on its own

Most FIRE apps put the answer behind a paywall. This one never does. Finding your FIRE number, watching the countdown to your financial-independence date, and pinning that countdown to your home screen are all free, with no account and no ads. Pro is for the planning you do after you know your number.

Try it all first. Everything is unlocked free for your first 14 days, so you can explore every Pro tool on your own numbers before deciding.

Pro questions, answered

Is Pro a subscription?

No. Pro is a single one-time purchase you own — there is no subscription and nothing renews. New features that ship later are included.

What is free without Pro?

The core is always free: your FIRE number, the live countdown, the home-screen and lock-screen countdown widgets, full input editing and recompute, a one-tap net-worth update, the growth chart, milestone reminders, a manual target-date override, the real (after-inflation) return toggle, and the “How this is calculated” breakdown. You never hit a wall to see your number.

Can I try Pro before buying?

Yes. Everything is unlocked free for your first 14 days after setup. When the trial ends the app settles to the free tier — your data stays, and you can unlock Pro any time.

Does my plan sync across devices?

Yes, privately. Your plan syncs through your own iCloud account (Apple’s private database). There is no account to create and no server of ours — the App Store privacy label is “Data Not Collected.”

Do Family Sharing and restore work?

The one-time unlock supports Family Sharing, and “Restore Purchases” re-applies it on a new device or after a reinstall, at no additional cost.
