# A 9-krona Swedish utility that hit #1 on the paid chart off a single LinkedIn post

**What it is** A Swedish iPhone utility: pick your municipality, and it writes that municipality's full-year school holidays into your calendar with one tap. 9 kr one-time purchase.

**Why it blew up** A boss posted on LinkedIn and Facebook on the first day of fall break (10-26), got heavily reshared, and parents nationwide were searching for break dates the same week. Plus, in Sweden's Top Paid chart a few dozen sales is enough to reach the top, so 10-27 hit overall Top Paid #1.

**C** **How you could ride it** In small countries like Norway, Denmark, or Finland that lack a native equivalent app, build a 'one-tap add to calendar' app with data you verify municipality by municipality. Push it onto the paid chart with your own network before the week the whole country goes on break. Treat it as a practice run or a way to build reputation, not as a business.

Grade C: the playbook is clear and repeatable, but free web tools already do the same thing, 9 kr a sale, used once a year. The chart push rode on the founder's personal network and one seasonal peak; follow-on earnings are at most a few thousand dollars. Chatter in small circles

The owner of a small Apple-device shop in Karlstad, Sweden built an app: pick your municipality, and it writes that municipality's school holidays into the iPhone calendar with one tap, for 9 kr one-time. On the first day of autumn break he posted about it, and by the next day it was #1 on Sweden's overall paid chart. The lesson here is the playbook, not the business: the function already exists for free on the web, and the money is tiny.

### One post on the first day of autumn break

On Oct 27, 2026, Joakim Bank posted on LinkedIn: "Swedish App Store #1 is my nine-krona app." He said he had released the app, called Läsårstider ("school year times"), six weeks earlier: "It's autumn break now. Yesterday I posted on LinkedIn and Facebook, it spread fast, and today it's #1 on the Swedish paid chart. It feels unreal." The post later collected 196 likes and 23 comments.

He is the owner of Attimo AB, a company in Karlstad that resells Apple devices and provides IT services. This is the only app under its developer account. When he first launched on Sep 11, he posted: "Last week I got fed up with entering all the holidays and term dates into my calendar by hand, so I built an iPhone app covering all 290 municipalities in Sweden. 9 kronor, one-time payment, and one tap puts every holiday into your calendar. If you like it, please share it or leave a review on the App Store." That post got only 42 likes and didn't move much.

Both posts were about the same thing; the only difference was timing. The second one landed on autumn break.

### What it is

Sweden's autumn break, Christmas break, sports break (sportlov), and Easter break are each set by the individual municipality. 290 municipalities publish their dates on their own websites, in wildly varying formats. This app packs the holidays for every municipality across 2026/27 school year into one place: choose your municipality (or let it guess from your location), tick the breaks you want, press the button at the bottom, and the holidays land in your system calendar with the correct start and end dates.

The store page highlights several points: each municipality's data is read directly from the municipality's official website, with the source and last verification date shown at the bottom of the page; whether to include the surrounding weekends is up to you for each break; the home screen has a countdown to the next holiday; it requests only calendar write access and "will never see what you have scheduled"; there are no accounts, no analytics, and no ads, and all data stays in the app. It is Swedish-only and requires iOS 26.5 or later.

### Why this week

Three things came together.

**Timing.** In 288 of the 290 municipalities, autumn break falls in week 44, which is Oct 26 to 30. Families across the country take the same week off and all want to know "when's the next break?" His second post went up on Oct 26, the first day of autumn break.

**His network.** A local shop owner with years in the Apple business has a LinkedIn and Facebook following made up largely of business owners and IT people, many of them parents who use iPhones. The post was the only channel he confirmed; I found no trace of ads, TikTok, or X.

**The Swedish paid chart has an absurdly low bar.** On Nov 6, Sweden's #5 paid overall app had no ratings at all, #8 had 1 ratings, and #19 had 5. This app itself has only 9 ratings to date (average 4.9). My estimate is that a few dozen sales a day is enough to reach the top 10, and one personal-network post can push it to #1.

### What happened next

| Date | Sweden paid overall chart | Score |
|---|---|---|
| 10-27 | #1 | — |
| 10-28 | #3 | 3 |
| 10-30 | #2 | 5 |
| 11-01 | #9 | 6 |
| 11-04 | #12 | 9 |
| 11-05 | #22 | 9 |
| 11-06 | #12 | 9 |

On the education paid chart, it sat at #1 from 10-28 to 10-31, then moved between #3 and #6. On Nov 2, the local paper Västgöta-Bladet ran a story titled "Former Tidaholm resident's app hits #1 on the App Store" behind a paywall, with little impact. Once autumn break ended, the ranking dropped to the teens; it held on the strength of chart visibility and never fell off.

It doesn't need retention; the official site itself says one use per school year is enough.

### How much money

Very little. 9 kroner minus Apple's cut leaves about 6 kroner per sale, under 0.6 dollars. Even if it sold a few thousand copies around autumn break (a guess), that's revenue in the low thousands of dollars. It's a shop owner's tool built for himself and listed on a whim, not a business.

### Who it's competing with

There is almost no moat on features. The free site skollov.nu has archived records going back to 2013 and covers 290 municipalities, each with a downloadable calendar file (.ics). skollovet.se is a newer ad-supported site that also exports to calendars and adds a "holiday stacking planner." Skolporten has a national summary PDF. School-system apps used by individual schools only show their own school.

What it adds is this: it's the only native app on the Swedish App Store that does this job (searching by name and description, only it shows up), it's one tap, it's ad-free, and it comes with a real founder's story. That's enough for people to pay 9 kr, but what carried it was the post and that week, not the product.

The same thing already exists in other countries: Schulferien & Feiertage and Ferienplan in Germany, and School Holidays Australia in Australia, the earliest of which was listed 2008 years ago.

### If it were you

**Verdict:** What's worth learning is the playbook, not the business. Pick a public calendar that varies by region and needs checking every year, make it a one-tap add-to-calendar app, and post before the week the whole country needs it. Small-country paid charts are easy to climb, but the payoff is still only a few thousand dollars (estimate).

**Who it's for:** Developers who already have a local network (LinkedIn, Facebook, parent groups) and live in small countries like Norway, Denmark, or Finland that lack a native equivalent app (an inference; search the local store yourself before launching). It suits anyone wanting a low-cost chart run, a portfolio piece, or some reputation to support their main job.

**Who it's not for:** Anyone hoping to earn a living from it; anyone without a local network who expects organic store traffic (the chart push depends on that post); anyone aiming at big markets like Germany or the US, or markets with established incumbents.

**How to build it:** You need to read the data from each local government website yourself and note the sources and verification dates. That is the one thing you can offer that free aggregator sites can't. Request only calendar write access; no accounts, no ads. Sell it as a one-time purchase priced at the "no-brainer" level. Once one country is done, the same shell can be reused with new data for the next: school holidays, state public holidays, garbage collection days.

**How to acquire users:** Copy his two steps: on launch day, post something like "I got fed up with manual entry, so I built this" and ask people to share and review; save the real push for the first day of a nationwide break. Once it's on the chart, post a chart-showing update so local papers have something to write about.

**When to get in before:** Winter and sports breaks in the Nordic countries mostly fall in February (week numbers vary by country; check locally). Launch and data verification need to be finished by mid-January. If you miss that, the next peak is August, before the new school year starts.

**What it means if you misread it:** ① This Swedish app did not return to the Top Paid top 10 on the next sports break (February, where municipalities are spread across weeks 7 to 10). So the autumn break spike came from one-off reach, not real demand. ② The Top Paid top 10 in your country is clearly harder than "a few dozen sales." Check the ratings on the top 10 apps. If they all have hundreds or thousands of reviews, don't expect a single post to get you there. ③ Apple or Google may have built "subscribe to school holidays by region" into the system calendar itself.

## Läsårstider: alla skollov (iOS, id 6810124239): why it could run up the charts

> Research date 2026-11-06. Sources: our appstore library (app_day / app_profile, se store), iTunes lookup, the developer's website, LinkedIn, Västgöta-Bladet, Appdex, competitor websites.

### One line

A one-time 9-krona iOS app built by Joakim Bank, owner of a small Apple reseller/IT shop (Attimo AB) in Karlstad, Sweden. Pick your municipality (290 in total), and it writes that municipality's school holidays into your iPhone calendar with one tap. The day before the autumn break week (around 10-26), he posted on LinkedIn and Facebook; it spread through his network, and the app climbed to #1 (10-27) on the Swedish overall paid chart. Two things made this possible: the Swedish paid-chart bar is extremely low, and the timing landed exactly on the nationwide autumn break week (week 44). The product has no exclusive capability; free websites can also export .ics calendar files.

### Key facts

- Listed 2026-09-10, version 1.1 (2026-09-14), priced at 9 kr, Swedish-only, education category. It is the only app under the developer account and requires iOS 26.5+ (iTunes lookup).

- Rankings (appstore library, se):
    - Top Paid overall: 10-28 #3 → 10-30 #2 → 10-31 #5 → 11-01 #9 → 11-04 #12 → 11-05 #22 → 11-06 #12.
    - Education Top Paid: 10-28~10-31 #1, then #3~#6.
    - Appdex logged it at #1 on Top Paid overall on 10-27 ([Appdex](https://tools.appdex.co/app/lasarstider-alla-skollov-6810124239)).

- Rating count: 10-28 had 3 ratings, 11-04 rose to 9, then flatlined (11-06 still 9); average 4.89.

- The Swedish Top Paid chart has a low bar. On the 11-06 Top Paid overall chart, #5 Tävlingskollen had 0 ratings, #8 Chromagraph 1, #19 The House of Tesla 5 (appstore library, app_profile). So by inference, a few dozen sales a day gets you into the top 10. 9 kr minus Apple's cut is about 6 kr per sale, so total revenue is small.

### 1. Why it took off

- **The trigger that got traction: the founder posted on LinkedIn and Facebook.**
    - On 11 he posted "I got tired of manually entering holidays into my calendar… 9 kr one-time… please share and leave a review". It got 42 likes and 3 comments ([LinkedIn post 1](https://se.linkedin.com/posts/joakimbank_appen-l%C3%A4s%C3%A5rstider-alla-skollov-appstore-activity-7504144561255079936-Wf-W)). That post didn't spark anything; our data starts at 10-28, when it had only 3 ratings.
    - Around autumn break week he posted again: "It's autumn break now, I posted on LinkedIn and Facebook yesterday, the response was huge, and today the app is #1 on the Swedish Top Paid chart". That post got 196 likes and 23 comments ([LinkedIn post 2](https://se.linkedin.com/posts/joakimbank_f%C3%B6rsta-plats-p%C3%A5-appstore-i-sverige-%C3%A4r-min-activity-7520873739358547969-c3iO)).
    - The source is confirmed by the founder himself; the channel was resharing through personal networks.

- **Timing: autumn break week plus "plan next school year" demand.** skollovet.se data shows 290 of the 288 municipalities have autumn break in week 44 (2026-10-26~30). That week parents are asking "when is the next holiday?", which is exactly the pain the post described. After week 44 ended, rank fell from #1 to #9~#22.

- **A local newspaper amplified it once.** Västgöta-Bladet, a local paper owned by Bonnier, reported on 11-02 "Former Tidaholm resident's app hit, once #1 on the paid chart, fell to #4 on Monday" ([Västgöta-Bladet](https://www.vastgotabladet.se/tidaholm/ex-tidaholmarens-appsucce-lag-etta-pa-app-store/)). It's paywalled local news with limited reach; the brief return to #9 on 11-03 may be related (unverified).

- **Why people paid: 9 kr has almost no decision cost, and it puts everything into your calendar at once.** The post pitched it as "9 kr one-time, one tap to put it all in your calendar", so users didn't have to check 290 municipal websites with different formats. The founder is an Apple reseller, and his LinkedIn network is mostly local business owners and IT people, many of them iPhone-using parents.

- **Retention isn't the point.** The official site itself says "once per school year is enough" ([lasarstider.se](https://www.lasarstider.se/)). It's a one-time purchase tool and doesn't depend on retention.

### 2. Differentiation

| Competitors | Channel | Time / scale | How it differs |
|---|---|---|---|
| skollov.nu | Web | The domain has archives going back 2013 years, with content updated continuously for 2025 years (Wayback); covers 290 municipalities | Free, every municipality has a downloadable .ics, nearly identical function. It adds a native app, location-based municipality suggestions, optional adjacent weekends, and a countdown widget. |
| skollovet.se | Web | The current version looks like a new site: the sitemap lastmod is 2026-10-31,2023 years ago and there's no Wayback archive; 289 municipalities; monetized with ads. | Free, also has .ics, plus a "holiday planner and bridge-day optimizer". It's an SEO content site; it doesn't have content-site traffic and relies on the App Store plus social spread. |
| Skolporten school-year summary | Web / PDF | Long-established | Only PDF summaries, can't import to calendar |
| Individual municipal websites | Web | Has been around all along | 290 formats, manual entry required |
| School-system apps like IST Home / SchoolSoft / Edlevo / Vklass | iOS/Android | Used uniformly by schools | Parents already have them, some show schedules, but only for their own school, with no one-tap bulk import into the system calendar (not checked one by one) |
| Similar apps in Germany / Austria / Netherlands / Australia (Schulferien & Feiertage, Ferienplan, School Holidays Australia, etc.) | iOS | 2008–2026 | The same model already exists in other countries. In the Swedish App Store, searching by name and description turns up only this one (appstore library long-tail full app_name/app_text). |

Bottom line: **functional differentiation is weak** (free web pages offer the same .ics). The real differences are three:

1. It's the only native app of its kind on the Swedish App Store, with no rival in iPhone users' minds or in the store;

2. Privacy and credibility packaging: it only requests calendar write permission, data is built in, and it labels each municipality's data source and verification date;

3. A credible real-founder story.

It worked because of distribution and timing, not differentiation. Differentiation only explains why people would pay 9 kr instead of using the free web pages: native, one-tap completion, on iPhone.

### 3. Growth tactics (evidence)

- Personal LinkedIn and Facebook posts: confirmed (founder's own account, second post 196 likes).

- Local newspaper coverage: confirmed (Västgöta-Bladet, 11-02).

- Store search / paid-chart exposure: inferred. After reaching #1, exposure from the paid overall and education charts themselves kept it at #9~#16 for a week.

- Ads, TikTok, X: nothing found. x-radar shows 0 posts in the last 60 days; no related TikTok videos found.

- Review prompting: the first post explicitly asked people to "leave a review" (a legitimate practice).

### 4. Visibility and copycats

- Visibility: it spread within small circles. The founder shared the paid-chart #1 on LinkedIn, and there's one local newspaper article; no national media coverage, no X discussion, no disclosed revenue.

- Copycats: none on the App Store yet. skollovet.se is a recently updated free web competitor with the same "verify by municipality, add to calendar" pitch, but there's no evidence it's copying this app.

### 5. Takeaways

- Look for public calendar data that varies by administrative region and must be checked every year: school holidays in Norway/Denmark/Finland, German states, Swiss cantons, waste collection days, election days. Build a low-priced one-time-purchase app that writes to the system calendar in one tap, and post before the demand peak (holiday week).

- The paid charts in small countries have very low barriers. A single founder-network post can push an app to #1, and chart exposure after charting can sustain it for a week.

- Use privacy as a selling point and a credible design that labels data sources, to set yourself apart from ad-supported free web pages.

### 6. Uncertain

- Actual sales and revenue (inferred to be small, tens to hundreds of sales a day).

- The exact date of the chart push: Appdex logged 10-27, our data starts on 10-28.

- Whether the next peak can be repeated: winter break, sports break (week 7~10, staggered across municipalities), and updates for the next school year's data.

- When skollovet.se launched, and whether it has any causal link to this app.
