The measurement gap
1,100
live ads behind a shrinking install base
1. Two sentences, 662 days, 1,100 ads
Rock Identifier runs 1,100 active Meta ads, 16.9x the Education median of 65, and has barely touched the copy. The top 2 have each run 662 days, rank 3 is at 661, and the median of the top 13 is 624. Only 2 lines exist: instantly identify any rocks, crystals, gems, minerals and more by a snap, on 9 of the 13, and a version that swaps minerals for knowing their value, on 4. Every ad is video and every ad links to the web rather than the App Store. The value variant is the interesting one; it speaks to the person hoping a found stone is worth something. Rock Identifier runs one plain benefit sentence, one hope-based variant, many videos behind each, and a landing page before the store.
2. A 3.99 week over a 29.99 year
Rock Identifier lists 10 in-app purchases at 5 distinct prices. The week costs $3.99, the month $7.99, the year $29.99 or $39.99 (a 1.3x spread), and a $69.99 item sits at the top. The cheapest annual is 31% of 12 monthly payments, so the yearly plan is the intended landing spot and the $3.99 week is the entry. Revenue per download is an estimated $5.98. Reviews show the two kinds of user the ladder serves: one hoping to sell stones to a company and relying on the identification being right, another who cancelled a trial and still saw a charge attempt. 49 of the latest 200 (24.5%) mention price, trial or subscription and 28 are negative. The cheap weekly entry brings people in, and the trial exit decides whether they leave a bad review.
3. Installs fall faster than revenue
Between Dec 19, 2025 and Oct 18, 2026, Rock Identifier's estimated monthly downloads fell from 259K to 101K, a -61.0% change, with a 310K peak on Sep 1. Estimated revenue held up far better, from $690K to $605K (-12.3%) after an $828K peak the same day. Both lines dropped sharply in the latest month, -50.2% for downloads and -25.3% for revenue, while the Meta ad count rose 13.1% to 1.1K. Spending more to get fewer installs while revenue holds suggests the paying base is older cohorts renewing, not new users converting. Meta targeting fits a collector audience: 31.7% of spend to 35-44, 25.4% to 45-54, nearly even by gender, 62.7% in the United States. For a smaller app the lesson is to separate renewal revenue from new-user revenue before reading a chart like this as stable.
4. The measurement gap
Rock Identifier keeps 1,100 ads live on 2 sentences while installs change -61.0% and revenue holds near $604K. Which cohort is paying, the collectors who converted in 2025 and keep renewing at $29.99, or new users arriving from a 662-day-old video? Whether the value-hunting line or the plain identify line brings the payer decides if the spend is maintaining the base or wasting it.

How we built this teardown
- Revenue and downloads are third-party app intelligence estimates as of Oct 16, 2026. Store intelligence estimates for a single app can be off by 30% or more. Treat them as a range, not a figure from the developer. Daily revenue and download series cover 304 days ending Oct 18, 2026.
- Ads come from the public Meta Ad Library. "Days live" counts days since an ad first appeared. Spend and audience breakdowns start from Meta's EU transparency figures; country splits outside the EU are modeled.
- Prices, ratings and ranks come from the App Store (US storefront) on the same date. Prices differ by country and by paywall offer. Review stats use the latest 200 US reviews from Apple's public review feed.
- Category medians are computed across 86 Education apps with active Meta ads in our set of 860 subscription apps.
- Written by Hyunjong Choi. Ads, prices and estimates are refreshed every 30 to 90 days. Updated Oct 19, 2026.
