One buzzword brought 150k users: the Beginner Adult's Handbook hit #1 on the App Store with zero ads. The valuable part is the playbook

The line "I'm just a Beginner Adult," which went viral on Threads during Chinese New Year 2026, was picked up by an indie developer in Taiwan who makes Notion templates, and he used it as the name of his app. He started posting as soon as the product had one or two pages. The pre-launch post got 423k views and over 20,000 beta sign-ups. It launched on Jul 31, hit #2 on iOS that night, and later reached #1. He spent no money on ads, and revenue is close to zero. This piece covers how he did it, why the two Hong Kong and Macau copycats didn't take off, and what you can actually take from it.

A line a child stumped him with

During 2026 Chinese New Year, someone on Threads posted about a small moment: a child asked a question he couldn't answer, so he said he was just an "ordinary adult" and told the kid to ask a "senior adult" instead. The post went viral. Yahoo News and DailyView both covered it under the headline "resonating with millions". Over the following months, young people in Taiwan used "Beginner Adult" to joke about themselves: not knowing how to file taxes, how to rent a place, or which department to visit at the hospital.

Huang Guanting (Threads @__yasac, whose main business is Notion templates and digital productivity systems) spotted a name nobody had claimed: everyone calls themselves a junior adult, yet no product is called "Junior Adult Handbook." He wrote in his Sep 1 newsletter:

"'Beginner Adult' is probably a buzzword by now. If I don't get it out there fast, I think it'll soon become a LKK, so I put the app out with only a page or two, before even figuring out the features, and went straight to community exposure."

LKK is Taiwanese slang for "old and outdated". He grabbed the name in the few months before the meme died out.

What it actually is

A "grown-up life manual" for young people in Taiwan: taxes, renting, seeing a doctor, religious observances, getting documents, labor rights, and subsidies, each explained in plain language with official sources you can check yourself. It adds two things beyond plain articles:

• Toolbox: red-envelope calculator, how to sort trash, laundry care label guide, life calendar, "life subscriptions" (track recurring monthly charges), disaster-prep SOP, where to keep paper documents.
• Community: Posts need moderation, and users can report and block. The positioning is "no question too dumb": he said on Threads, "even I get lectured by preachy guys," so he opened a safe haven inside the app. For hard questions, an AI assistant called "Carrot-kun" helps find sources.

All the content is public information, and he admits it himself: "Wikipedia, subsidies and the like are all just public information anyway. You can Google it yourself." What he built is turning articles into a tool.

How it took off

Step one: post before you write code. Since June he has been posting development updates and beta recruitment on Threads, nonstop. His read on Threads is clear: the algorithm favors "topics," posts should be "shareable, suspenseful, the more like shitposts the better," but the product has to actually hold up, because "people on Threads have extremely sharp eyes," and any bait-the-user trick gets spotted at a glance.

Step two: ride someone else's hot post. The key one was a reply under someone else's viral "so many creative ideas" post: "I'll share mine too," with a pre-download video attached. It got 423k views. Comments already included people asking for an Android version.

Step three: build up first-day downloads with beta and pre-orders. The beta signup passed 20,000 people, but TestFlight only allows 10,000 installs at a time. He turned on iOS pre-download, having heard that concentrated downloads help climb the charts. Launch was planned for Aug 1, but it went live early on the evening of Jul 31, peaked at #2 that night ("lost to Shopee's seller center"). The traffic maxed out the free database and he paid to upgrade the servers on the spot. He later posted a screenshot of "#1 on the App Store chart" (which chart isn't specified).

Step four: users spread it for him. After launch, Threads, IG and FB saw organic recommendations: "Grown up, now there's a manual" and "3 app built just for adulting newbies, a treasure." The in-app "what level adult are you" quiz became a sharing tool: people posted "I'm a senior adult, 80 points," tacking on "search Adulting Handbook on the App Store." Several meme-riding quiz webpages also popped up online.

Ads: zero spent. "After launch many people asked how much I spent on ads. The truth is, nothing at all... I just caught a big wave of traffic bonus."

Current numbers

150k against 245 ratings, a high ratio; 150k probably counts downloads or signups, not active users (inferred). The first Android reviews said "Been waiting since Apple launched, Android finally here today" and "waited so long": people were waiting, but the buzz had passed, and Play gets only a hundred or two installs a day. Daily installs jumped to several hundred around Oct 29, overlapping with the public vote period of the Taiwan indie dev competition "Golden Source Award" (10/20–10/30). Whether that was the cause can't be confirmed.

He said himself in September: "Retention is lower than I expected," a side effect of a burst of downloads. The most active part was actually the LINE group originally opened to collect bug reports: members write their own rules and organize their own offline meetups.

Where the money comes from: basically nowhere

He hates third-party ads ("they wreck my carefully designed interface, so absolutely not") and doesn't dare charge ("I'm one person! I'm sure I'd make mistakes! Who'd pay for wrong information!"). The app has only a tip jar ("抖内") of about NT$150. His other plan is group buys and vendor sponsorships via a bulletin board on the homepage; the official site already lists a partnership email.

His own words in September: the workload "has completely become a full-time job, even exceeding one (but no income XD)."

For him, the app's return is reputation: traffic into his newsletter subscriptions, Threads following, Notion templates and consulting work. He's also wondering whether "the app could become the next battlefield for influencers."

Who's following

The pattern is clear: the ones that copied the template are one to two orders of magnitude smaller. The Hong Kong one did best, 8,000 users, which is still only a twentieth of the original's self-reported count. The cause isn't the product: Hong Kong and Macau never had their own viral moment for this meme; "adulting" is a borrowed word there.

If it were you

C: worth learning from, not worth copying. What's valuable is his playbook, not the product. "Adulting" is already claimed by him in Taiwan, and it's cooling off; other Chinese-speaking regions already have copycats, all tiny; and the product itself barely earns anything.

Who it suits: indie devs who want a personal brand, people who already earn from newsletters, templates or courses and need a shareable piece to funnel traffic to their main business; people who understand the topic algorithms of a particular social platform.

Who it doesn't suit: people who want to make money from the app itself (the content is public information, users won't pay, and the author himself doesn't dare charge); people who want to move the "adulting handbook" to Malaysia, Singapore or mainland China (there's no such meme there, and Hong Kong and Macau have shown that transplanting drops you one or two orders of magnitude); people without the time to maintain content and run a community year-round (he's one person and already has a full-time job).

How to do it: treat it as a method, not a category. Watch self-deprecating trends just emerging on Threads, Xiaohongshu and Douyin, pick one that "everyone is saying but nothing is named after yet," and use the meme as the product name. The product can be a very thin layer: plain-language summaries of public information, a few calculators and checklists, a quiz. But the interface should look good and every piece of information should cite its source. Launch on iOS and Android together; don't do what he did and let Android lag by 5 weeks and miss the first wave.

How to get users: start posting once the product has one or two solid pages. Posts should read like casual shitposts, and replies under hot posts on the same topic borrow traffic. Collect a beta waitlist and open pre-downloads to concentrate first-day downloads and push the local category chart. Build a quiz with a shareable score so users naturally mention the app's name when they share it. No ad spend at any point.

When to move: before the meme's peak has passed, within the first two or three months. "Adulting" went viral around Lunar New Year, and he launched in late July, half a year later. Even so, he was already late; his own view was that without fast exposure it becomes a LKK (a has-been).

Signs the call was wrong: ① if it starts earning real revenue from group buys or sponsorships before year-end, meaning these meme products can be monetized, it deserves a higher grade than C. ② If the Hong Kong one or another non-Taiwan version reaches 50k+ users, it means a "life manual" can take off on its own without the meme, and then localizing by region is worth doing. ③ Conversely, if you pick a new meme using this method and your pre-order post gets under 100k views, then this round's windfall came from his personal feel for Threads, not from the method itself.
