A meditation app that only times you when your eyes are closed, and the top spot is a monk: Thailand's nak collected 1,000 ratings in three months, powered by the founder's own TikTok

nak is a timer built by a small Bangkok studio. The front camera checks whether you're really closing your eyes and stops the clock when you open them. Wrapped around it is an otter that evolves into a Naga king, plus cards, streaks and a leaderboard. It launched in August with only Thai and English, and three months later it ranked in the top three meditation apps on the Thai App Store by rating count, behind only Calm and Headspace. Anyone can copy the mechanic, and others built it first without it taking off. nak worked half because of the product and half because of the founder's 120K-follower philosophy and Buddhism account. Anyone who wants to follow can borrow the mechanic and the localization approach, but first they need to work out where their traffic comes from.

"Someone sat for 1,086 minutes, and when you click in, it's a master"

In October, a Thai user on X reposted a screenshot: "Someone made a meditation app, and it sat at number one for 11 days with 1,086 minutes of sitting time. Everyone got curious and clicked into the account. It's a master. Hahaha, who can compete with that." The screenshot came from Palapol Chobisara, founder of nak. (Oct 25)

1,086 minutes is about 18 hours, or an average of an hour and a half a day with eyes closed. The meme was quickly picked up by Thai gaming and tech media: Sheapgamer's Instagram post got 9,235 likes, Extreme IT posted on Facebook, and on Oct 28 MGR Online posted a video to its TikTok account with 3.28M followers, getting 92K views and 7,030 likes (TikTok, 11-06).

In the days that followed, nak's cumulative installs on Google Play jumped twice: 10-31 gained 655,11-03 and 1,799. On the Thailand App Store, its ratings 11-03 brought in 17 new ones in a single day, versus the usual one to eight.

The joke wasn't planned. It grew out of the mechanic itself. Only "eyes closed counts" makes meditation time rankable, and once it's rankable people get curious who's on top.

What it is

The first line of the store page reads: "Sit on a floating island with a little otter." Open it and you get a timer running from 1 minutes to 1 hours. Prop up your phone and the front camera checks on-device whether your eyes are closed, and the clock only runs when they are. The store description is blunt: "No more guessing whether you really sat for ten minutes."

The timer is wrapped in a game layer:

• In Thai, "นาก" (otter) and "นาค" (naga) sound the same, so your otter evolves all the way into a Naga king. There are 31 nak forms and 234 cards, and you draw one each time you finish 5 minutes of sitting.
• There are daily streaks and tasks, and seasonal ranking tiers named after Buddhist cosmology ("human realm 24 hours → heaven realm 70 hours → emptiness 200 hours").
• You can claim territory on a world map.
• Sign in with LINE, Apple or Google in one tap. There's also a web version.

The app is free with no ads. The paid tier is nak pass, 99 baht for 30 days in the Thai store (about $3). It gives double points, unlimited mode, and 40 messages a day with the AI nak. The website says 15% of revenue goes to a stray dog foundation.

Thai App Store reviews show who it's hitting. One user wrote in Oct 27: "I've tried meditating for years and never stuck with it. This app made me happy. The otter is so cute, I want to open it every day." They even dedicated the merit to the dev team at the end. Another in Oct 18: "I only ever scroll my feed, but with this I can sit still longer." The complaints are mostly about battery drain. A three-star review in Nov 2 said "the phone gets so hot I'm scared the battery will blow up," and someone in Oct 11 said the battery drops fast. The camera stays on the whole time. That's the cost of how the mechanic works.

Metric

Comparing Thai App Store rating counts side by side (11-06): Forest 17,438, Calm 4,383, Headspace 2,002, Insight Timer 1,463, nak 1,021, Finch 369. Insight Timer built its count over more than a decade in Thailand; nak reached seventy percent of it in three months.

There's another side too: on both stores its chart position has dropped from the teens to the seventies, and the October surge is fading. It's not in the top 40 of the Thai Health top-grossing chart, so revenue is probably small (inference).

Where the traffic comes from

Mostly the founder's own account. Palapol's TikTok @tententch has 120K followers and 5.89M likes. He normally posts about philosophy, Buddhism and AI, and also jokes. In April he even posted a video of himself ordaining at a forest monastery. His followers already care about meditation and Buddhism, and the app link sits in his profile.

The day before launch he posted a video of himself chanting scriptures, 290k views. On Aug 22 a clip titled "Am I breathing right?" hit 3.03M views and 210k likes, and that same day he added a "link in bio" post. On Aug 29 Thai outlet Spacebar ran a feature saying nak quickly charted in the Thai store's Health & Fitness top list after launch.

He then turned the product-building process itself into content: Aug 25 "4 days +500", 110k views; Aug 26 "Can also cheat", followed three days later by "We now have AI catching cheaters"; 9 and October nearly one post a day covering new versions, adding background music, adding voiceover, "Only one otter has its eyes open in the app". Most get one to ten thousand views. In between are pure philosophy posts: one in Oct 14 at 300k, and a quote compilation in Nov 1 at 537k (TikTok, 11-06).

Second, the joke grew out of the mechanic itself: the monk at the top of the leaderboard, which media picked up.

Third, small-account seeding. On TikTok there are small-account reviews with a few hundred to over a thousand views, and posts on Instagram and Lemon8. They all make the same point: "the camera checks whether you really closed your eyes" and "made by Thais, free, and cute."

No sign of paid acquisition. The install curve rises and falls with content spikes, unlike sustained paid buying.

Who it's competing with

The "camera verifies eyes closed" idea wasn't invented by nak; Sit came first. The difference is that nak turned the mechanic into a game, wrapped it in Thai culture, and had people distributing it. Sit shows that a mechanic alone means nobody knows about it. I haven't seen any copycats, and almost no one in the English world discusses it (90 posts on X in the last 0 days).

If it were you

One-line verdict: the mechanic is worth copying, but you have to change the country or the habit, and bring your own traffic. Copying a plain eyes-closed timer will most likely just make you the next Sit.

Who it suits: people who have a content account in a religious or practice community, or small teams that can recruit creators like that; people who know a market big players haven't localized, such as Indonesia, Malaysia (chanting, prayer), Myanmar, Sri Lanka, Cambodia (Theravada Buddhism), or Vietnam.

Who it doesn't suit: people with no content channel who plan to rely on organic store traffic or pure paid ads. The meditation market is held by Calm, Headspace and Insight Timer, and nobody searches for a new timer. Anyone hoping for big money should also be realistic: nak hasn't entered the Thai top-grossing chart in three months, and subscriptions cost only 99 baht a month. This looks more like a small, well-liked business with modest revenue (inference).

How to do it: two routes. One is to change the market: keep the "eyes-closed timing + animal evolution + leaderboard" formula and swap in local cultural motifs, for example chanting timers and prayer streaks for Indonesia, and Theravada practice terms for Sri Lanka and Myanmar, while plugging into local national apps for login. The other is to change the behavior: find a self-discipline habit where people can't tell if they really did it, and use the camera or a sensor to turn it into a comparable number, such as planks, waking early, vocabulary review, or standing meditation. Bring battery drain down first, since the most common complaints in nak's reviews are the phone overheating and draining fast.

How to get users: copy nak's playbook and post on the founder's or a partner creator's account as you build. Share "4 days, 500 more people", share cheaters and how you catch them, share who's on top. Each iteration becomes one video, and "the timer stops when you open your eyes" can be explained in a single frame. Launch the leaderboard early, because the story of who's at the top is the best free material you have.

When to move: nak is currently only in Thai and English and hasn't gone global. Aim to establish yourself in another country before the first half of 2027; once nak or a big player makes "eyes-closed verification" standard, a reskin won't be enough.

Signs you've misread it: ① nak's chart position keeps falling out of the top 150 on the Thai free Health chart and its ratings stop adding more than a handful a day, meaning it was just a spike and the mechanic didn't keep people; ② nak launches its own Indonesian or Vietnamese version and enters the local Health chart, so the market-change route has already been taken by it; ③ Calm, Headspace or Insight Timer adds "eyes-closed verification."
