1. A cheap year, a family lifetime
Six in-app purchases, six prices. Monthly plans cost $6.99 and $9.99, annual plans $19.99 and $29.99, and lifetime plans $99.99 and $149, with Family Plan and Family Lifetime options in the names. The cheapest year costs 24% of 12 monthly payments, so the month mostly exists to make the year look cheap. Family plans fit the product: parents who worry about their own screen time often worry about their children's too. Revenue per download is an estimated $2.0. For one sec, the family tier lets one worried parent pay for the whole household, which may lift revenue per buyer without new installs.
2. The founder tells the story
I used to spend so much time on Instagram and TikTok, so I created this app. That founder voice opens the top ad, live 1058 days, and the second, at 1057 days, says the founder built one sec for personal use and was surprised by the results. The third, at 1054 days, uses Tim Cook's concern about screen time and three hashtags. Other lines call it the most annoying app you will ever have, and one is in German. The top 13 hold 9 lines, all video, all to the web. A personal story ages well because it never claims a feature that can go stale. For one sec, the founder story has outlasted every other line, so the maker's voice is the asset to keep.
3. Young men, US and Germany
Meta Ad Library spend estimates put lifetime spend at $47K for a reach of 2.8M. The United States takes a modeled 70.3% of spend and Germany 24.5%, a market where the founder story also runs in German. Men take 64.1% of spend and women 22.9%, and the two youngest age bands, 25 to 34 and 18 to 24, take 37.8% and 34.3%. That is the audience most hooked on short video apps. Germany is also the app's best chart, at #85. For one sec, Germany is the second market in spend, copy and charts at once, which makes it the clearest place to measure the founder ad outside English.
4. The measurement gap
one sec sends all of its top ads to the web and has run the same founder stories for close to three years. The question is whether those old ads still bring buyers of the $19.99 year or a lifetime plan, and whether the US or the German audience pays more per install.
How much does one sec cost?

- 02
Compare markets, not only campaigns

- 03
An annual buyer and a monthly buyer look the same at install. Retention by channel shows which source keeps paying.

How we built this teardown
- Revenue and downloads are third-party estimates from AppKittie, snapshot 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 296 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 AppKittie models.
- 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 53 Productivity 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.
