App Market Opportunity Research

App market opportunity research

Assess a defined app niche using competing products, observed distribution signals, release activity, and customer evidence. Separate an opportunity hypothesis from demonstrated demand, market size, or a revenue forecast.

Setup

Set CRAWLORA_API_KEY to your key from crawlora.net. Run the bundled scripts/crawlora.sh from this skill directory or by absolute path. It sends x-api-key to https://api.crawlora.net/api/v1; keep the key in the environment. Read reference/endpoints.md for selected dataset, store, review, and Trends calls.

Map the niche and test the signals

1. Define the user problem, storefront/country, device, language, and comparison period. Discover candidates with /datasets/apps/search and relevant live App Store/Google Play searches and similar-app results. Validate actual product capabilities; search rank and category membership alone do not prove rivalry.
2. Resolve store identities: iOS numeric track ID versus bundle ID, and Android package name. Verify publisher/official site before merging cross-store apps. Preserve country/device variants. The apps dataset uses repeatable platforms filters; chart history uses singular platform for iOS only. Missing platform classifications mean unknown coverage, not incompatibility.
3. For /datasets/apps-charts/search, hold store, country, chart type, category, and device constant. chart_type is top_free, top_paid, top_grossing, or new; underlying store collection names differ. An ordinary request resolves the latest available snapshot_date, which may lag today. For app history, pass exact app_id with sort=date_desc and omit date.
4. Compare ranks only within the same chart definition and dates. Deduplicate chart × snapshot × app observations. Missing dates or absent chart entries mean unobserved/unranked within coverage, not rank zero or zero downloads. Do not infer download/revenue volumes from ordinal ranks or cross-store ranks.
5. Refresh a bounded shortlist with /appstore/app and /googleplay/app. Dataset price_cents is in cents; do not compare it directly with live-store prices in major currency units. Compare currency, subscriptions/in-app purchases, rating counts, positioning, and updates. A free install is not free ongoing use. iOS has no install count here; Android install figures are not current monthly active users. Use /appstore/version-history/{id} for numeric iOS IDs; Google Play's latest update field alone is not a full release history.
6. Read a comparable review sample from each product. App Store reviews use country, sort=mostRecent, and pages; Google Play uses country, lang, sort=newest, num, and returned pagination tokens. Count unique eligible reviews by theme (n/N), keep dates/version/source, and link short excerpts. A complaint frequency in a selected sample is not population prevalence.
7. Use Google Trends only when it adds evidence about the underlying problem. Discover values through /google/trends/enums, /locations, and /categories under the same prefix. POST flat JSON to /google/trends/explore/interest-over-time with 1–5 keywords, geo, time_range, and type=web. Compare terms in one request; scores are relative, not app installs or absolute demand.

Synthesize an opportunity brief

Return the user problem, competitor matrix, matched chart trajectories, release evidence, review themes, and gaps. For each opportunity hypothesis, show supporting and conflicting evidence plus a concrete next validation step. Keep data freshness, sampling bounds, unknowns, and assumptions visible.

• Do not turn a small indexed category count into a total market size, or a review/rank spike into proof that a particular release caused growth.
• Store labels and category IDs differ; use returned values and included discovery calls rather than transferring Apple's numeric IDs to Google Play.
• Keep Trends normalization and missing-data flags; separate independently scaled requests. See Google's data FAQ.
• Dataset pages max at 100 with a 10,000-result window. Stop on repeated pages or tokens. Back off on 429, retry transient 5xx once, stop on 401/403, and check application code. Report unavailable sources without inventing results.
