Plant your tree
Open the app. No sign-up. Four fields:
- Your name, so the app knows what to call you.
- Target passive income (£/year): what you'd want to live on.
- Monthly contribution (£): what you'd put in each month.
- Starting amount (£): this becomes your cash to invest.
Your FIRE number updates as you type: target income ÷ 4%. £24,000 a year needs £600,000. Tap Plant my tree. You can change all four later in Profile.
