2. Napkin economics

Price

$2.99 one-time or $1.99/mo subscription

Competitors in App Store are mostly free, but 7 are paid. Pricing data is limited, so this is a hypothesis based on utility app standards.

Does it add up

Negative LTV/CAC ratio (-0.73) with current assumptions. Requires higher conversion or lower CPC to be viable.

Customer acquisition cost

$8.20 (Assuming 10% conversion rate from click to install at $0.82 CPC).

Paid search: CPC $0.82 · bids $0.15–$0.67 · competition: Low

Revenue per customer

$5.98 (Assuming $2.99 price and 2.0 lifetime multiplier).

Assumptions to validate:

  • 10% conversion rate from click to install.
  • 2.0 lifetime multiplier for free users.
  • CPC remains stable at $0.82.
  • Price point of $2.99 is acceptable.
