No. 5 on Korea's Google Play weather chart with only about a thousand installs a day: a veteran weather studio's new skin

In early October, "Live Weather - News," an app launched in August with a forgettable name you couldn't even find in search, suddenly jumped from one or two hundred installs a day to over a thousand, reached #6 on Google Play's Korea weather free chart by November 5, and was listed on weather charts in 14 countries at once. Behind it isn't a new team but Amber Weather, which has been making weather apps for ten years. This piece covers why it charted, where the money comes from, what you can take from it, and why I don't recommend copying it.

A five-star review

On Oct 7, a US user named Karen Koch gave it five stars on Google Play: "It doesn't just tell me the local weather, it has news too. I don't think I'll ever delete it." The next line is more telling: "I don't think there are too many ads either. I actually like looking at the ads. I'm of the older generation, and I often find things in them that interest me." 15 people marked it helpful, and the developer thanked her 6 days later.

That review pretty much sums up the business: a local weather plus local news app whose users are older, willing to scroll a feed, and don't mind ads. The app charges nothing and earns from ads.

What it is

A free, ad-supported weather app with no in-app purchases: hourly and 14-day forecasts, rain radar, severe weather alerts, plus a news feed. The first screenshot on the store page isn't weather, it's news, with the bold headline "Weather & Local News, All-in-one App," and on the phone is a story from Patch, a local news site in suburban New York: "Storm topples scaffolding, two workers injured." The bottom has three tabs, and news comes before weather.

The news is aggregated via RSS. The store description includes a dedicated disclaimer for news publishers: if we pulled in your site, it means we're using your RSS; if you don't want to be included, contact us to remove it, and if you want to be included, contact us too.

Who's behind it

The developer name on the store page is Smart Utils Dev Team, but the "About the developer" section lists Amber Mobile Limited, with an address in Central, Hong Kong, a phone number with a Beijing prefix (+86 185), and a website of amberweather.com (Google Play, 11-06). That's Amber Weather: Beijing Amber Chuangxiang's global-expansion weather brand launched in 2015, whose team traces back to Infolife, one of China's earliest companies to go global, and which owns a set of older weather plugins with millions of installs (Baidu Baike, Google Cloud customer case studies).

Two more apps sit under the same developer account: HideU, a calculator-lock app launched in 2021 with about 270M cumulative installs and still gaining 960k a week; and SafeBrowser, launched in May 2026 with 460k installs (Google Play, 11-06).

Amber co-founder Song Rui said two things in an interview with an overseas-expansion outlet that fit here: weather needs are "use it and leave, you shouldn't extend session time for commercial purposes"; and on product selection, "don't focus only on retention and frequency... acquisition might be cheap enough to recover ad spend quickly." The first line refers to the older products; this app uses a news feed to do exactly what it says shouldn't be done, extending session time. The second line describes exactly how this app makes its living.

How it took off

Install curve (AppstoreSpy estimates): Sep 8 cumulative 714, Sep 29 3,825, Oct 5 7,444, Oct 13 16,788, Oct 27 32,191, Nov 6 41,731. The first five weeks were one or two hundred a day; in early October it jumped past a thousand a day, then settled between several hundred and three thousand a day. 7-day new installs: 9,540.

This is the shape of an acquisition tap being opened, not the shape of word of mouth spreading. Several clues point the same way:

• Charting in 14 countries at once: 11-06 Korea #5, Japan 44, Argentina 44, Spain 49, US 50, Mexico 60, with South Africa, Hong Kong, Nigeria, UAE, Singapore, Brazil, Turkey and Germany between 68–130 (Google Play weather free chart). When several markets pop at once, it's usually because they were bought together.
• No discussion at all: X shows only 30 posts searching "Live Weather - News" over the last ~0 days, and on the web it only appears on auto-generated listing pages.
• Very few ratings: 158 ratings in total, averaging 4.4 stars, with five stars making up three-quarters.

So it's most likely bought user acquisition (inference, I haven't seen its ad creatives directly). Another possible source is cross-promotion within the family: on HideU's Korean store page, the "other apps by this developer" section shows its Korean name, 실시간 날씨 & 뉴스; whether the apps cross-promote inside the product is unverified.

"#5 in Korea" sounds less impressive than it is

Korea's weather free chart ranks by recent velocity, so the bar is low. On the same day, #1 Nice Weather gained 310k in a week, #4 Meteored has over 8,000 million cumulative installs, and Korea's official weather agency app gained only 5,045 in a week and still ranked #7 (Google Play, 11-06). An app getting about a thousand installs a day worldwide reaching #5 shows the chart is easy to climb, not that it has many users in Korea.

Its real users are more likely in the US: the screenshot city is New York, the news is US local news, and the visible reviews are in English (inference).

Where the money comes from

Only ads. No in-app purchases, no subscription. Weather is something you open for a glance and close, once or twice a day, which leaves little room for ads; add a local news feed, and users keep scrolling, with an ad slot on every screen. Older users like Karen Koch, who "like looking at the ads," are exactly the audience these feeds are worth the most to. The US's NewsBreak follows the same path of "local news + feed ads."

Revenue is not visible. At 40k installs, it can't be large (estimate). For Amber, the value of this app may lie less in what it earns by itself and more in using a new package name, ready-made weather data and ad integrations to test whether "weather + news" can push per-user ad revenue above what it costs to acquire a user.

The bad reviews also show where the product sits: one Oct 4 one-star review says "the radar is totally inadequate, it doesn't show rain where it's supposed to fall... zooming to street level is a joke, seriously false advertising, uninstalled". Another five-star review says "I've had this app on my phone for five years". The app has only been on the store for just over two months, so that user most likely mixed it up with a different weather app they had before. It's also possible the store listing was swapped (unverified).

Who it's competing with

At least 8–9 similar apps launched in the past 2026 years under "Live Weather / Daily Weather / Weather Alarm," and it's only one of them. Its growth ranks around #9 among new weather apps in the same period. This niche has no open spot, and it doesn't lead on any metric.

If it were you

Verdict: C. Worth learning from, but don't copy it. It works because of things you don't have: ten years of weather data and ad integrations, a payback-tested paid acquisition model, and a sibling app with 270M installs. The product itself gives users no reason to pick it.

Who it fits: Teams already running an ad-monetized utility app, with a paid acquisition payback model, who could test "weather page + local news feed" as a way to raise ad revenue per user inside their own weather or utility app.

Who it doesn't fit: Indie devs with no paid acquisition experience who are counting on organic store traffic. The weather charts are full of paid-acquisition utility apps, and ASO alone won't get you in. The Korean chart is easier to enter, but only because everyone is racing for it.

If you still want to build it, how: Don't build another generic weather app. The interesting part is the half shown in its screenshots: local news plus local weather for older US users. Pick one clear region or audience (a state, or an immigrant community with its own language), make the news source more local and cleaner than an RSS grab bag, keep weather as a supporting element, and monetize with an in-feed ad.

How to get users: Paid acquisition only. Start with a small budget in one country and check whether a user's ad revenue over 7 days covers the install cost. If it doesn't, stop. Don't count on scale to dilute the cost.

Window: No window. Weather is a year-round need, so there's no first-mover race. That also means there's no rush.

Signs you've misread it: ① It passes several hundred thousand installs before December and, after paid acquisition stops, daily installs don't fall back to one or two hundred. That would mean the news feed really drives organic retention and word of mouth, so the product has real substance. ② The same developer account launches another "weather + news" package, or Amber adds the news feed back to its older weather app. That would mean they've run the numbers and the approach pays back, so it's worth copying in your own utility app. ③ The opposite: if by December its chart positions have all dropped and updates have stopped, the test failed, and even a well-resourced team couldn't make this work.
