Determine what users would actually pay, not what the developer hopes to charge. Anchor WTP to pain intensity, desire strength, competitive pricing, and real monetization signals from market_insights — never to the cost of building. Pricing is the single decision with the highest leverage on unit economics: a $1/mo difference at 1,000 users is $12K/year.

| Field | How it informs pricing |
|---|---|
monetization_evidence | The strongest signal. If competitors are visibly making money (in-app purchases mentioned in reviews, subscription pricing in App Store listings, sponsored content), the market has validated WTP. If monetization_evidence is empty across all platforms, WTP is unproven — discount aspirational price and flag risk. |
| Platform narratives — Reddit | Users discuss pricing directly: "I'd pay for X if...", "Y is overpriced because...", "$Z/mo is too much for just..." These are raw WTP signals. Extract any price mentions. |
| Platform narratives — App Store | Review complaints about pricing reveal the ceiling: "Great app but not worth $X/mo." Review praise about pricing reveals the floor: "Amazing value at $X." |
| Platform narratives — TikTok | Creator recommendations often mention price as part of the hook ("this FREE app...", "worth every penny of $X"). Signals whether freemium or premium positioning resonates with the audience. |
trend_velocity | Rising-fast markets can support premium pricing (early adopters pay more). Declining markets face price pressure (users comparison-shop harder). |
| Model | Best for | Risk | Indie sweet spot |
|---|---|---|---|
| Freemium → subscription | Habit-forming apps with daily use, feature-gated value | Conversion friction; most users stay free forever | $3–$8/mo or $20–$50/yr |
| Subscription only (paywall) | High-value, immediately obvious ROI, professional tools | High churn risk; must prove value fast | $5–$15/mo |
| One-time purchase | Utilities, tools with clear one-time value, privacy-focused apps | No recurring revenue; must rely on new users | $3–$10 |
| Consumables / credits | Variable usage (AI generations, exports, premium content) | Unpredictable revenue; usage may decline | $1–$5 per credit pack |
| Freemium + consumables | Apps where core is free but power usage costs (AI, storage) | Complex to balance free vs. paid tiers | Free tier + $2–$10 packs |
| Lifetime deal | Launch phase only — use for early adopter cash and reviews | Destroys LTV; never use as primary model | $20–$60 (3–5× annual price) |
| Tip jar / patronage | Content-focused, community-driven, or open-source-adjacent | Very low conversion; unreliable revenue | $1–$5 tips, rare |
| If the app... | Recommended model |
|---|---|
| Has daily usage with progressively unlocked value | Freemium → subscription |
| Delivers immediate, obvious ROI in one session | Subscription only or one-time purchase |
| Produces output that varies in volume (AI, exports) | Freemium + consumables |
| Is a simple utility used occasionally | One-time purchase |
| Requires trust before users see value (health, finance) | Extended free trial → subscription |
| Competes with free alternatives that are "good enough" | Freemium (generous free tier) → subscription for power features |
From competitors.json, extract pricing data for all direct competitors:
competitive_min (cheapest) and competitive_max (most expensive).If competitors.json has limited pricing data, supplement with market_insights monetization_evidence and App Store narrative pricing mentions.
The Van Westendorp model uses four price perception thresholds to identify the acceptable price range. Since we can't survey users directly, we estimate each threshold from available data:
| Threshold | Question (conceptual) | How to estimate |
|---|---|---|
| Too cheap (floor) | Below this price, users suspect low quality | Half the cheapest competitor's price. If app is free, this is $0 (no floor). |
| Cheap but acceptable (low) | Feels like a good deal | Competitive minimum price. Discount slightly if the app offers less than the cheapest competitor. |
| Getting expensive (target) | Fair price — users would consider it but think carefully | Competitive modal price, adjusted by desire multiplier (Step 3). |
| Too expensive (ceiling) | Above this, users won't consider it regardless of value | Competitive maximum price × 1.2. Cap at the "pain threshold" — the maximum users pay for similar apps in the category. |
The optimal price point sits between "cheap but acceptable" and "getting expensive" — this is the target WTP.
wtp_low = cheap_but_acceptable
wtp_target = getting_expensive (adjusted by desire multiplier)
wtp_aspirational = midpoint between getting_expensive and too_expensive
Desire strength from desire_scores.json directly affects pricing power. Apps that tap into primal desires command premium pricing; apps that solve mild inconveniences face price resistance.
| Primary desire driver | Premium multiplier | Rationale |
|---|---|---|
| Survival (health, safety, financial security) | 1.3–1.8× | Users pay more when stakes are high. Health and money apps can charge premium. |
| Status (achievement, appearance, signaling) | 1.5–2.0× | Status is inherently scarce — users pay for differentiation. Luxury/prestige positioning works. |
| Belonging (community, connection) | 1.0–1.3× | Users value belonging but expect community features to be free (social norms). Premium only for exclusive communities. |
| Control (mastery, organization, reducing chaos) | 1.2–1.5× | Moderate premium. Users pay for control when the alternative is stressful. |
| Curiosity (learning, discovery, novelty) | 0.8–1.2× | Lowest premium. Curiosity-driven apps compete with free content (YouTube, blogs). Must add structure/accountability to charge. |
Apply the multiplier to the competitive modal price:
desire_adjusted_target = competitive_modal_price × desire_multiplier
If desire_strength_label = "weak", do not apply any multiplier — the app lacks the emotional pull to justify premium pricing.
If the secondary desire driver is different from the primary and scores ≥ 3, add a +10% bonus. Apps that tap two distinct desires (e.g., survival + control in a health tracker) have stronger pricing power than single-desire apps.
Use these ranges as a sanity check against the Van Westendorp and desire-adjusted estimates:
| App category | Subscription WTP range (monthly) | One-time WTP range | Annual discount sweet spot |
|---|---|---|---|
| Health & fitness | $5–$15/mo | $8–$30 | 40–50% off monthly |
| Nutrition / diet | $5–$12/mo | $8–$25 | 40–50% off monthly |
| Meditation / mental health | $5–$15/mo | $10–$30 | 50–60% off monthly |
| Finance / budgeting | $3–$10/mo | $5–$20 | 30–40% off monthly |
| Productivity / task management | $3–$8/mo | $5–$15 | 30–40% off monthly |
| Habit tracking | $2–$6/mo | $3–$10 | 40–50% off monthly |
| Creative tools (photo/video) | $3–$10/mo | $5–$20 | 30–40% off monthly |
| Education / learning | $5–$15/mo | $10–$30 | 50–60% off monthly |
| Dating / social | $5–$25/mo | N/A (subscription dominates) | 30–40% off monthly |
| Parenting / family | $3–$8/mo | $5–$15 | 40–50% off monthly |
| Utility / scanner / converter | $1–$4/mo | $2–$8 | 50–60% off monthly |
| AI-powered tools | $5–$20/mo | $10–$40 consumable pack | 30–40% off monthly |
If the estimated WTP is more than 2× above the category range, it's likely too optimistic. If it's below the category minimum, the app may struggle to sustain development.
If the recommended model includes a free tier, estimate what percentage of free users will convert to paid:
| Factor | Higher conversion (toward 8–12%) | Lower conversion (toward 1–3%) |
|---|---|---|
| Value gating | Core value is free; premium unlocks power features or removes limits | Core value IS the paid feature — free tier feels empty |
| Free tier generosity | Generous enough that users form habits before hitting the wall | Either too generous (no reason to pay) or too stingy (users leave) |
| Pain of free | Free tier has clear, felt limitations (ads, watermarks, usage caps) | Free tier works fine for most users |
| Social proof | Users see premium features in action (shared content with branding) | No visibility into what premium offers |
| Trial exposure | Time-limited trial of premium (7–14 days) shows value upfront | No trial; users must imagine premium value |
Category benchmarks for freemium conversion:
| Category | Typical conversion rate | Top-quartile rate |
|---|---|---|
| Health & fitness | 2–5% | 8–12% |
| Productivity | 3–6% | 10–15% |
| Creative tools | 3–7% | 10–18% |
| Education | 2–5% | 7–12% |
| Finance | 3–6% | 8–14% |
| Utility | 1–4% | 5–10% |
| Social / dating | 2–8% | 10–20% |
| AI-powered | 4–8% | 12–20% |
Use the typical rate as the base estimate. Adjust toward top-quartile if:
Most indie apps benefit from offering both monthly and annual plans. The annual plan serves as the anchor.
| Discount depth | Effect |
|---|---|
| 20–30% off monthly | Subtle incentive. Users who prefer monthly will stay monthly. Low commitment-capture rate. |
| 40–50% off monthly | Sweet spot for most B2C apps. Enough savings to feel meaningful, not so deep it signals desperation. |
| 50–60% off monthly | Aggressive — use for high-churn categories where locking in annual users dramatically improves LTV. |
| > 60% off monthly | Signals the app isn't worth the monthly price. Avoid unless in launch/promotional phase. |
Recommended annual price = monthly price × 12 × (1 - discount). Present the annual plan as the default/highlighted option.
Some ideas have a viable path to both consumer and business revenue. Evaluate if the app concept could serve both:
| Signal that B2B2C path exists | Example |
|---|---|
| Users would expense the app to their employer | Productivity tools, professional development |
| A business version could serve teams | Shared dashboards, admin controls, team analytics |
| Content or data from the app has business value | Health data for employers, fitness for corporate wellness |
| The consumer app is a wedge into workplace adoption | Personal Slack → company Slack, personal Notion → team Notion |
If B2B2C path exists:

target WTP is the price used by downstream skills (cac-modeler for LTV, tam-sam-som-builder for revenue projections). Getting this wrong cascades errors through the entire scoring system.monetization_evidence from market_insights is empty across all platform files, flag pricing as "unvalidated" in the rationale. This is a key risk — the market may not support paid apps.stale_after date, note that competitive pricing may have shifted and recommend refreshing.
