Unit economics — what does a user actually cost?
Slide the controls below to see the net margin (or loss) on a given user. Defaults match
the three tiers defined in UsageTrackingService.swift. Costs are best-effort
estimates — the goal is break-even intuition, not a P&L. All assumptions are editable
at the bottom of the page.
Tier
Apple's cut
Credit usage mix — how they spend 1000 credits this period
Sliders auto-normalize so percentages always sum to 100.
Revenue (pre-Apple)
$0.00
/ month
Revenue (after Apple)
$0.00
after 30% cut
Total cost to us
$0.00
Gemini + Lambda + Rek
Net margin
$0.00
— of net revenue
