One Question On 13 Ads For 264 Days, An Annual Above Monthly
memoryOS: Memory Games is an Education app from Encoder Inc. that teaches memorization techniques through video lessons from a memory champion and a 3D mind palace game. As of Oct 2026 it makes an estimated $203K a month on 41K downloads, 2.0x the Education median revenue of $101K on 0.9x the median downloads. All 13 of its longest-running Meta ads carry the same three-word question, How good is your memory???, and 9 of them have run exactly 264 days.
Key takeaways
- 116 active Meta ads, 1.8x the Education median of 65, out of 583 found, plus 181 Apple Search Ads creatives. 12 of the 13 top ads are video and all 13 link to the App Store.
- A single copy line across the top 13, How good is your memory???. Nine ads have run 264 days, the rest 200 to 246, so the set launched together and has barely been touched.
- The app lists 10 in-app purchases at 8 prices: $6.99 weekly, $5.99, $16.99 and $29.99 monthly, and $89.99, $148.99, $149.99 and $174.99 annual across Essential, Expert and Student plans. The cheapest annual is 125% of 12 cheapest monthly payments.
- Over 84 days estimated downloads moved from 39K to 41K, a 4.6% change, after a 53K peak on Oct 1, 2026, and estimated revenue from $195K to $204K, also 4.6%. Live Meta ads changed -17.0% in 30 days, from 182 to 151.
- Meta Ad Library spend estimates put lifetime spend at $15K reaching 1.1M people, 67.7% on men, 31.1% on the 25 to 34 group and 61.1% in the United States, with Germany at 16.0%.

The measurement gap
13 of 13
top ads share one question, 8 prices behind it
1. Three words, 264 days, 13 ads
Every one of memoryOS's 13 longest-running Meta ads asks the same thing: How good is your memory??? Nine have run 264 days, one 246, one 239 and two 200, so the top of the account is a single batch that has not needed replacing. Twelve are video, all 13 link to the App Store, and none mentions free or a price. The question works as a self-test hook: a viewer answers it in their head and the video shows the technique. Around that fixed top layer sit 116 live ads, 1.8x the Education median of 65, 583 found over time, and 181 Apple Search Ads creatives, so the volume is footage rotating under one line. MemoryOS poses the question the product answers, short enough to read in a thumbnail, and leaves it alone while it works.
2. The year costs more than the months
memoryOS lists 10 in-app purchases at 8 distinct prices. A $6.99 week and $5.99, $16.99 and $29.99 months sit below four annual plans at $89.99, $148.99, $149.99 and $174.99, split across Essential, Expert and Student tiers. The cheapest annual is 125% of 12 of the cheapest monthly payments, so the year is sold as a bigger course rather than a discount, and the annual prices sit 1.9x apart. Revenue per download is $4.95 on 41K monthly installs, 2.0x the category median revenue on 0.9x the downloads. Reviews are kinder than most in this set, with 29 of 200 (14.5%) mentioning price and 20 negative, one arguing a fixed set of lectures should not be priced like a streaming service. MemoryOS's tiering invites that exact objection whenever content does not refresh.
3. Germany as the second market
Meta Ad Library spend estimates cover $15K of lifetime Meta spend and 1.1M people reached. The United States takes 61.1% of spend but 40.5% of reach, while Germany takes 16.0% of spend for 20.9% of reach, France 7.19% and Denmark 6.68%. Men receive 67.7% of spend, and ages spread across 25 to 34 at 31.1%, 35 to 44 at 29.5% and 45 to 54 at 20.7%. Category ranks are faint, #54 in Norway and #92 in Australia, so the audience is bought rather than found in charts. A 4.9 rating across 16.7K reviews and a 4.16 average in the latest 200 say the product holds up. MemoryOS keeps the US as its core market and runs the same English-language creative in northern Europe.
4. The measurement gap
memoryOS has run one question across 13 Meta ads for up to 264 days, backed by 116 live creatives and 181 Apple Search Ads, into a store page with 8 prices from a $6.99 week to a $174.99 year. The question is which clip under that fixed line, and which country, produces the learner who buys an Expert annual plan rather than one of 41K monthly installs who tries a week.

I really tried. But the music and the images were so juvenile. The videos were awkward. I guess I need this sort of thing in a different format. Or maybe there …
Extremely interesting subject but the price structure, which is similar to Netflix for example, which offers continuous new content, makes no sense. The lecture…
How to measure a playbook like memoryOS's
memoryOS has asked How good is your memory on 13 ads for 264 days and runs 181 Apple Search Ads creatives beside them, so the question is which clip and which channel produce a subscriber at $89.99 or more.
- 01
Connect Meta and see cost next to results
Spend, installs and in-app events land in one report by campaign, so channels get compared on the same numbers.
- 02
Send trial and purchase events back to Meta
Core sends mobile postbacks to Meta and three other channels, so the algorithm can optimize for payers instead of cheap installs. Growth adds more channels.
- 03
Connect RevenueCat for revenue by campaign
Subscription revenue joins the install data, so each campaign shows return on ad spend, not only cost per install.

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 84 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 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.
