Dashboard connecting App Store, Google Play, and RevenueCat to AI inference costs, showing indie app publishers their margin per subscriber to optimize paywall and credit limits. · Mobile Analytics SaaS

DEAD SLOW · CAUTIOUS

5.4 ShipScore / 10

Automated SaaS helps time; RevenueCat dependence and unproven indie willingness-to-pay weaken it.

Condition: Twenty indie AI app publishers must commit to paying about $29/mo before RevenueCat or Costr-style tools cover mobile.

Part I — The Verdict what the instruments read

01 — The ShipScore breakdown

Control

C5: relies on RevenueCat and store APIs; RevenueCat could add this.

Entry barriers

E4: weekend-cloneable, but no strengthening incumbent tracked in mobile niche.

Need

N5: tracked corpus (coldcaller, Calendesk, Glamour) irrelevant; only X margin complaints.

Time-freedom

T8: data pipes and dashboards run without operator time once built.

Scale

S5: global but limited to indie AI-powered subscription apps.

What the five commandments measure

C — Control	Do you own the customer, or does a gatekeeper stand between you and revenue?
E — Entry	How hard is this to copy once it works? A rival's existence isn't the question — the durability of their advantage is.
N — Need	Is demand proven with money rather than vibes?
T — Time	Can income detach from your hours, or did you buy yourself a job?
S — Scale	How far does it reach without linear cost?

Scored on the evidence below, against CENTS as we've adapted it plus a Buffett-style moat reading of every rival — the same referee for every idea, including the ones we generate ourselves. The verdict follows the arithmetic: we never relabel a score to make it read better, and the weakest commandment is always named. The exact rubric stays in-house so the scale can't be written for.

02 — The pace test — $1M/yr

At $29/mo (assumed category price), you need 2,874 subscribers for a $1M/yr pace.

Nearest tracked rivals on that curve:

coldcaller.pro

$4k 5%

↑ moat widening · +23%/mo

Calendesk

$21k 26%

Glamour

$11k 13%

A rival's moat trend is its verified-revenue trajectory, not its rating — a 4.9★ incumbent with eroding revenue is a different opponent than a widening one. How it's computed →

Part II — The Evidence the receipts, good and bad

03 — Rival scan — corpus tracks 3 similar

coldcaller.pro	verified MRR $4k · CENTS 6.6 · revenue trend: widening (+23%/mo) (trustmrr)	↑ moat widening · +23%/mo
Calendesk	verified MRR $21k (trustmrr)
Glamour	verified MRR $11k (trustmrr)

Costr — Already ships per-customer AI cost tracking for SaaS margins and could extend to mobile.
AI Observly — In-build cost and margin visibility tool targeting the same pain.
Helicone/Langfuse — Established LLM observability tools already capture per-user inference cost data.

04 — Demand evidence

X complaints: flat subscriptions bleed margins when power users burn tokens.
X chatter cites AI gross margins of 30-60% vs 80%+ for traditional SaaS.
Thin evidence: no Reddit signals, no funded companies, and no relevant verified-MRR rivals tracked.

05 — Risks

RevenueCat ships native AI-cost and margin charts, which would erase the product.
Indie publishers are price-sensitive and may settle for spreadsheets.
Mapping inference cost to a specific subscriber needs SDK instrumentation, which adds onboarding friction.
Launches in this space show low engagement so far.

06 — Kill switches — what kills this with one decision

RevenueCat roadmap — A built-in cost-per-subscriber chart would make a standalone dashboard redundant for most users.
RevenueCat/App Store API access — Restricting or pricing third-party data access would cut off the subscriber revenue side.

Part III — The Plan if you insist on proceeding

07 — What this scan can't tell you

No verified revenue for any mobile-specific AI-margin tool, so the willingness-to-pay ceiling is unknown.
Cannot tell how many indie apps have inference costs large enough to care about.
Cannot see whether RevenueCat is already building this.

Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-10-14.

08 — The wedge & the next step

One-line SDK that tags LLM calls with the RevenueCat user ID and shows margin per subscriber and per paywall tier.

Cheapest next step: DM 30 indie AI app founders on X who complain about token costs and pre-sell a $29/mo beta.

Not quite it? Spin the model
