Swiss navigation top-grossing #26 with only 1 ratings: the real situation of a mushroom-foraging map

Cepello is a mushroom-foraging map built solo by a Swiss developer. In Nov 6 it hit #26 on the Swiss App Store's Top Grossing chart in Navigation, yet it has only 1 ratings worldwide. Its chart spike came from a few expensive in-app purchases, not from a real business. It's worth a look because it stands for the dozen or so "where to forage mushrooms" apps that popped up across Europe in 2026, and because of its 2,176-page multilingual SEO site behind it.

A Swiss developer and the map he launched in September

Flavio Valceschini lives in Orbe, a small town in the canton of Vaud, and runs an IT services company. In 2026 he shipped several products under the same developer account: a idle game in June, a parkour game in August, Cepello in Sep 8, and another game three days later. Each has between 0 and 7 ratings. It's a typical one-person, AI-assisted, high-frequency shipping cadence.

For the first two weeks after launch, Cepello's core feature was actually broken. The release notes for the Sep 24 1.1.1 update say they fixed "all region detail pages appearing outside the forest, with empty content and no weather verdict." Before that, iOS users who tapped any area saw nothing.

By Nov 5 it had its 1st rating: 5 stars, no reviews (Swiss App Store, 11-06). The next day it charted at #26 on the Swiss Navigation Top Grossing chart, and the same day it debuted at #91 on the Swedish Navigation Top Grossing chart.

What it does

In one line: you pick a mushroom species, and it tells you which Swiss forests it's likely to grow in, then whether it's worth going there right now.

The store page opens with "La forêt donne des indices. Cepello les lit pour vous." (The forest gives clues; Cepello reads them for you). Concretely, it works in two layers:

• Where: Switzerland is cut into 10-metre grid cells, and each cell gets a habitat score from 0 to 100 based on terrain, slope aspect, forest type and tree species, geology, soil pH, and vegetation zone. Each mushroom has its own ecological profile; so far there are 6 species: porcini, bay bolete, summer bolete, chanterelle, morel, and grey trumpet.
• When: it layers recent rainfall and the weather forecast on top, giving a "good chance", "possible" or "skip it" verdict along with a 14-day fruiting window.

It also includes fungus-picking regulations for each of the 26 cantons, and foraging logs stay on the phone with no account required. The free version only shows large areas. Precise 10-metre cells, weather filters and offline mode require payment: CHF 10 a month, CHF 60 a year, or a "founding member" lifetime one-time purchase at CHF 199 (Swiss App Store pricing, 11-03). The most prominent line on the homepage reads "The map helps you find them, never identifies them for you," with Swiss poison-emergency number 145 underneath.

What the #26 chart position tells you

Almost nothing. Look at its ranking on the Swiss Navigation Top Grossing chart over those ten days:

Jumping above a hundred places in a day and then falling back the next is the classic shape of one or two purchases a day. The Swiss Navigation Top Grossing chart has a very low bar: around #26 you find niche tools like Geocaching and Swiss Pro Map. Cepello's one-time tier is CHF 199 and its annual sub is CHF 60, so a single one-time purchase is probably enough to push it into the top 30 (inferred).

The other numbers line up too: 500+ downloads on Google Play. No press coverage found, and nobody on TikTok, X or Reddit has mentioned it. The founder hasn't posted any revenue. Only one competitor has written about it.

A competitor says it for them

In Nov 3, Mycora, a Swiss web-based competitor, published a German comparison page, "Which mushroom app suits Switzerland," listing Cepello in the first row with a fairly neutral description, and then added a line:

Between July and October 2026, at least 8 new mushroom-map or fruiting-forecast apps hit the Swiss App Store, including Cepello, pilzen, ShroomCast, Shromu and MyBoletus. By Nov 3, none of them had more than 2 ratings in Switzerland.

That's what this category looked like this year: in a single mushroom season, a batch of near-identical products appeared across Europe at once.

Why did they all show up together this year? Two things converged. First, swisstopo's data and Europe's soil and weather datasets are public. Modelling that used to take a GIS team several months can now be stitched together by one person with AI in a few weeks. Second, 7–October is mushroom season, and everyone rushed to launch for it. Once the barrier dropped, many people launched at once, and nobody broke out.

The Swiss mushroom apps that actually make money are a different kind

In the Swiss store, the mushroom apps that get traffic and revenue are photo-ID apps, not maps. Picture Mushroom has 2,084 ratings and ranks #18 on the Swiss Top Grossing chart. Pilze 123 sells for CHF 39.95 and has 428 ratings. Pilzführer LITE has 781 ratings (Swiss App Store, around 11-03).

This shows demand exists, and that Swiss people will pay for mushroom apps. But "what mushroom is this" is a question every forager asks every time, while "where should I go" is something experienced pickers already keep as their own secret spots, and first-time users find it hard to judge whether a map is accurate. Cepello's 10-metre precision sits behind the paywall. The free version only shows large areas, so users can't feel how much more accurate it is than rivals before paying CHF 60. Its price is 8 times pilzen's and 20 times Pilzgebiete's one-time price.

One thing it gets right: 2,176-page SEO

The most worth-copying part of Cepello isn't in the app, it's on the website. The cepello.com sitemap lists 2,176 URLs in four languages (French, German, Italian, English), and each language has:

• 397 "where to find" pages combining species × canton × terrain, such as "where to find porcini in the canton of Zurich";
• 71 guides, 27 pages on cantonal regulations and regional pages, and 16 species pages.

The site went live around Sep 11, and searches like "Steinpilze finden Zürich" or "application champignons Suisse" surface its pages. The pages are batch-generated from public data and templates, so the cost is low, and they target long-tail keywords. How much traffic they bring isn't visible from outside. Judging by 1 ratings and 500+ installs, they haven't converted users yet, at least not this season.

Its other acquisition efforts are small. A Facebook page has one 13-second video ("Cèpes, chanterelles, morilles : Cepello te montre…") with 2,900 views and 125 interactions, a number a brand-new page would get if it had been paid to push (unverified). The homepage carousel has a dozen harvest photos labelled as user shots, paired with Swiss German and French captions such as "Hüt hets richtig gfägt" (today was great) and "1,8 kg sur la balance" (1.8 kg on the scale). Their authenticity can't be verified.

The season is closing

Switzerland's main mushroom season ends in mid-November, and morels won't come back until 3–May next year. Over the next four months, the chart signals for every app in this category will disappear, and whether subscribers renew during the off-season is an open question. This season, none of these products broke out. When next season opens, everyone will start over from the same line, with products already built.

If it were you

C There's one trick worth taking, but don't copy it to build another mushroom map. It didn't break out, rivals already have several players in every European country, it's highly seasonal, and the revenue ceiling is low. Cepello's only real asset is its programmatic SEO playbook: small country × multiple languages × public geographic data.

Who it's for: indie devs who know GIS or can process public geographic data and can also write multilingual content, who can port this playbook to other hobbies where you need terrain and weather to decide where to go (inferred: fishing spots, stargazing spots, wild blueberries or truffles, which nobody has piled into yet), or to countries nobody has touched yet (this wave clustered in France, Germany, Switzerland and Italy; no equivalents seen in Northern or Eastern Europe, unverified).

Who it's not for: anyone wanting to build yet another Swiss or French mushroom map (the space is packed, and rivals already have comparison pages written). Anyone hoping for steady subscription income (demand exists only a few months a year). Anyone who won't create content and is relying only on organic store traffic.

How to build it: make "accurate" something free users can verify on their first try, like giving them one precise area for free, or letting them mark "went, found something." Build in push alerts ("the forest you follow is worth visiting this week"), since that's the only reason to renew outside the season. Price in line with rivals rather than starting at CHF 60/year.

How to acquire users: run programmatic SEO that copies Cepello's structure (species × region × terrain, hundreds of pages per language), launch two months before the season so search engines index it, then post real harvest photos in local foraging Facebook groups and forums.

Deadline: to catch next year's spring morel season, the SEO page needs to go live by January 2027; for the main autumn season, by July.

What would mean we got it wrong: ① before September next year, Cepello or any app in this batch gets 100+ ratings in the Swiss or French store, which would mean "where to forage" can drive real volume and is worth doing seriously; ② Cepello's SEO pages climb into the top three for local searches while ratings rise in step, which would mean this SEO playbook actually brings users and is worth copying; ③ the reverse: if most of this batch is delisted or stops updating when next season opens, even this move isn't enough, so just watch.
