A Thai "auspicious date calendar" got onto the Productivity charts: AMA packs 15 kinds of fortune-telling into one calendar. The pool is small, but the playbook can be copied

A solo Thai developer, August, launched an app called AMA. The shell is a "which days are lucky, which are unlucky" calendar; inside are Thai astrology, BaZi, Korean Saju, Indian Vedic astrology, tarot, and an AI you can "ask grandma." Instead of entering the crowded lifestyle category where fortune-telling apps cluster, it sits in Productivity, and stayed on the Thai Productivity Top Grossing chart for over six weeks. Its scale is still small and growth is slowing. What's worth watching is the playbook: the calendar as the entry point, push notifications to pull users back, subscriptions plus credits to collect money. No one is running this in other markets with a tradition of choosing auspicious days yet.

"Yesterday it suddenly notified me that tomorrow is an unlucky day"

In 2026 Oct 5, a Thai user gave AMA 1 stars with the title "Notifications are terrible": "Yesterday it suddenly popped up a notification saying tomorrow is วันกาลกิณี (an unlucky day). Notifications like this are unconstructive; they only make you anxious, and I don't see the point. Wouldn't it be better to let people open the app themselves?"

A month earlier, Sep 3, another user gave 5 stars: "I've always wanted an app like this, with everything, showing the daily star readings and the auspicious hours each day. After using it for a few days I found it also reminds you of good and bad days. No ads (hope you never add any). The apps I used before charged me almost every time I looked at something, and they were expensive."

The two reviews are about the same feature. A daily push saying "tomorrow is good/avoid" annoys some people and makes others open the app every day. A calendar became a daily habit that way, and that's where AMA's business started.

What it is

On the App Store it's called "AMA : Life Auspicious Calendar"; on Google Play, "AMA อาม่า : ปฏิทิน ฤกษ์มงคล" (Grandma: auspicious calendar). อาม่า is how Thai-Chinese families address a grandmother, and "ask grandma" is the AI Q&A inside the app.

The homepage reads "15+ divination methods packed into one app": Thai astrology, Mahasattha, BaZi, Saju, Vedic astrology, numerology, Western astrology, compatibility readings, Feng Shui Bazhai and Xuankong Flying Stars, palmistry. When you open the app, the first thing you see is a lucky/unlucky calendar, each day color-coded by how favorable it is, so you can read a whole month at a glance; it also marks moon phases, Buddhist holy days, and public holidays, and you can switch between Thai, Chinese, or both. Below that are five daily fortune readings (career, wealth, love, health, side income), a "life curve" plotting ages 15 to 90, plus compatibility readings and "countries that suit you."

The site makes a point of saying: "No AI fortune-telling; the program calculates charts from classical texts. AI only helps in some features by phrasing answers so they're easier to read." The line is aimed at users' suspicion that AI just makes things up.

The developer account is an individual's name, kritsana sucheethong. It has only this one app, listed on iOS in 2026 Aug 18, and on Google Play the next day. On LinkedIn he's a software engineer at a Bangkok company, with past work on top-up and virtual-gift systems for a live-streaming platform, plus server-side work on a game with gacha mechanics. AMA's monetization resembles that background (inference).

Why it's listed under Productivity

This is the main reason it could chart at all.

Nov 6 Thai Productivity Top Grossing: ahead of it are ChatGPT, Claude, Gmail, VPN, and CamScanner. #29 is Num Eiang (ปฏิทินมงคลน่ำเอี๊ยง), a 80-year-old Chinese almanac brand, with only 387 ratings on iOS Thailand. #44 is another lucky-day app, LockDay, with 683 ratings. AMA sits at #48,344. Very few Productivity apps can collect money from local users, and a few hundred ratings plus a bit of in-app spending per day is enough to reach the top 50.

Move it to Lifestyle and the picture changes. On the same day, the fortune-telling app "a ดวง", #43 in Thai Lifestyle Top Grossing, has 7,277 ratings, and "ดวง Live", which connects you to live human fortune-tellers, has 20,561. Both are one to two orders of magnitude above AMA. The same revenue in Lifestyle probably wouldn't reach the top 100 (inference).

Filing it under Productivity also has a benefit. The English store description is all about "turning goals into plans" and "seeing the days ahead"; divination gets a single line about "cultural belief systems" and "personalized perspectives." Apple reviews new astrology and fortune apps strictly and often rejects them as "duplicative." Framing it as a planning tool probably also helps it get approved (inference).

AMA's category and its lucky-day calendar positioning are largely copied from Num Eiang. The difference is that Num Eiang only covers Chinese date selection and lucky colors, while AMA includes five systems (Thai, Chinese, Korean, Indian, Western), so both Thai-Chinese and ordinary Thai users have a reason to open it.

The numbers: small, and slowing down

• Chart: From Oct 28 to Nov 6 it stayed on the Thai Productivity Top Grossing chart, bouncing between #26 and #78. On Nov 3 it peaked at #26 on Top Grossing and was #50 on Top Free that day. On Nov 6 it was back to #48 Grossing and #129 Free. Thailand only. The third-party chart tracker AppInsider recorded it at #25 on Productivity Top Grossing already on Sep 50, and it held that spot for about six weeks. The reason for the spike on November 2 and 3 is unclear.
• Ratings: Nov 6, Thailand: 344 ratings, average 4.86. It collected 28 ratings in the 71 days from launch to Oct 328, averaging 4.6 per day; in the 9 days after that it added only 16, under 2 a day.
• Android: Google Play 1,000+ installs, 4.8 stars (11-06). On Play, Num Eiang has 328k installs.

The only thing that can be confirmed is that people in Thailand will pay a monthly fee for this kind of app. It's too early to say it has "taken off."

Where users come from

• Content on X, @amaapp8. The account was created in April 2026, four months before the app launched. By early November it had about 800 posts and fewer than 1,000 followers. The posts are list-style threads and memes that Thai X's fortune-telling crowd (สายมู) loves to repost, such as "Western rising signs most likely to get dumped" and "Want a 'golden retriever' boyfriend? First check your 7th house 9 baseline, then see 'Pattaya 4.'" Each post links to a specific feature in the app, like the question "Where will my true love come from?" in the "Ask Grandma" feature. Thai X is the main home for fortune content, and this channel costs almost nothing.
• App Store search. In Oct 19 the Thai App Store name changed from "AMA ปฏิทินชีวิต" (life calendar) to the current English name, and the screenshots and description were changed with it (AppInsider). The Android name includes search terms like "ปฏิทิน" (calendar) and "ฤกษ์มงคล" (auspicious time).
• Push retention. This is the feature the two opening reviews mention: daily lucky and unlucky day alerts.
• Other channels are nearly empty. Instagram @amaapp8 has only 12 followers and 5 posts; the Facebook page has single-digit followers; searching its name on TikTok turns up no relevant videos. No evidence of paid ads was found, but not finding it doesn't mean it wasn't run.

Where the money comes from

Two tracks (App Store Thailand prices):

The website also has a page for topping up credits, which avoids Apple's commission.

Both tracks running side by side does get people paying, and it draws complaints too. In Sep 4, a 4-star review: "I thought Pro unlocked everything; turns out you still have to buy credits separately." In Oct 3, a 1-star review: "ChatGPT is more accurate for free, and you still have to pay, and tarot costs credits too." In Sep 5, a 4-star review said the readings sounded "very AI," with too much jargon: "If you're paying, you should get more than an explanation of where the stars are."

Actual revenue can't be confirmed. Thai Productivity Top Grossing ranks #26 to #78 correspond to modest daily revenue. My estimate is tens to a hundred or two dollars a day in in-app purchases (rough guess, low confidence).

Who it's competing with

No copycats copying AMA were found. There is no press coverage and no public revenue figures.

If it were you

Verdict: Worth trying. What's worth copying is the playbook, not the product itself. Use a daily calendar as the free entry point, push alerts to bring people back, wrap it in a "planning tool" shell to get into a low-barrier category, then collect money through subscriptions and credits. Thailand alone is a small pool, and AMA itself is slowing down. But other markets with date-selection and almanac traditions don't yet have this "all-in-one divination plus calendar" product.

Good fit for: developers who understand a local divination tradition (or can find partners who do), who can build iOS in-app purchases and subscriptions, and who can write memes in the local language.

Bad fit for: anyone who only wants to build an English astrology app, since Western astrology is already crowded; anyone unwilling to touch the controversial "unlucky day alerts" experience; and anyone hoping for quick big money. In one country, this category tops out at a few hundred ratings and a bit of in-app spending per day.

How to do it:

1. Market choices: Vietnam (lunar date selection and day-picking traditions), Chinese communities in Indonesia and Malaysia, Taiwan, Hong Kong. Start by checking local App Store Productivity and Lifestyle Top Grossing charts to see where local lucky-day and almanac apps rank and how many ratings they have. If the top 50 in Productivity can be reached with only a few hundred ratings, the pool is as empty as Thailand's.
2. Product: Start with the lucky/unlucky calendar and daily fortune layer, free and pushed every day. Make BaZi, compatibility readings, and AI Q&A paid credits. Don't launch 15 features at once; start with the one or two that locals trust most.
3. Put "calculated by the program, AI only does the wording" in the most visible spot. That's what users care about most. AI answers should read like plain language; AMA's complaints are about too much jargon.
4. Make subscriptions and credits clear. State on the paywall what Pro includes and what credits buy. AMA got bad reviews here.

How to get users: Follow @amaapp8's example: post list threads and memes on the platforms where the local fortune crowd is most active (X in Thailand; Threads and Dcard in Taiwan; Facebook and TikTok in Vietnam, most likely). Each post should point to a specific feature in the app. Put local search terms for "calendar," "lucky day," and "almanac" in the store name.

When to move: No need to rush, but earlier is better. A pool like this only has room for one or two winners per country, and whoever takes the calendar slot first builds the push habit. Demand for date selection peaks around Lunar New Year, so launching before January 2027 could catch a wave.

Signs you've misjudged it: Two or three months after launch, you still can't crack the top 100 in Productivity Top Grossing in your target market, or most reviews say "not accurate" or "can't understand." Either the pool is less empty than it looks, or the localization isn't deep enough. Also, if Apple rejects your fortune app as "duplicative" and the calendar shell doesn't get past review either, this path is closed in that market.
