Fuck Growth - Plan profitable mobile growth: LTV, CAC, and payback

Why I built it: Most UA forecasts are fragile spreadsheets with no cohorts, no fees, and fuzzy funnels. I wanted a fast, honest calculator that matches how growth really works. What it does - Cohort-based projections: LTV, ROAS, CAC, payback - Full funnel: install→trial→paid + direct subs - Retention editor (Month 0 = first charge), annual renewals - Fees, organic uplift, multiple products - Instant scenario tweaks with shareable links How it works Everything runs locally in your browser – no logins, no backend, no paywalls. Roadmap (tell me what you need most): channel/geo splits, CPI-vs-spend curves, SKAN/MMP lag presets, sensitivity bands, CSV import/export. Would love feedback from UA/growth folks: what would make this your daily driver?
