Games-only app stores: what Skich and Onside mean for publishers

A games-only app store is exactly what it sounds like: a third-party iOS marketplace that lists nothing but games, instead of trying to be a general-purpose catalogue with games as one tab among many. Two of the clearest examples in 2026 are Skich, which launched a games-focused iOS marketplace in the EU, and Onside, which positions itself as a games-and-apps marketplace live in both the EU and Japan. They matter to publishers because they’re testing a thesis the duopoly never had to: that a focused catalogue can out-discover a giant one.

If you run a studio or hold IP and you’re trying to work out whether these stores are worth your integration budget, this is the read we’d give you over a coffee — what they actually are, why “focused” might beat “huge” for discovery, and where the operational drag hides.

Why a games-only catalogue can beat a general-purpose one

The App Store and Google Play are general-purpose marketplaces. They carry banking apps, parking apps, fitness trackers, and your game, and their discovery surfaces are optimised for that breadth. Game discovery inside them has always been a compromise: a “Games” tab, an editorial team that features a handful of titles, and a search algorithm that has to serve everyone.

A games-only store doesn’t have that compromise. Every recommendation signal and editorial slot is about games. Skich, for instance, built its discovery around a swipe-to-match mechanic — users swipe through titles the way they would on a social app, build playlists, and see what friends are playing. That’s a model you can’t ship inside a store that also has to surface a tax-filing app. The bet is that genre-literate curation and social signals convert browsers into installers better than a general-purpose ranking ever could.

This is the same structural argument we made about the broader shift in the state of alternative app stores in 2026: the duopoly’s one-size-fits-all surface leaves cohorts and discovery patterns underserved, and that gap is where alternative channels earn their keep. Games-only stores are just the sharpest expression of it — they’re not trying to be a smaller App Store, they’re trying to be a better games shelf.

For a publisher, the practical upside is twofold. First, the denominator is smaller: on a curated games store you’re competing for attention against other games, not against every app on Earth, so a mid-tier title has a realistic shot at a featuring slot. Second, the audience is pre-qualified: someone who installs a games-only store is, by definition, there to find games. That’s a higher-intent visitor than the median App Store browser.

What Skich and Onside actually are (as of mid-2026)

Both stores exist because the regulatory door is open. Apple was forced to allow third-party iOS marketplaces in the EU by the Digital Markets Act — which entered into force on 1 November 2022 and became applicable on 2 May 2023, with designated gatekeepers having to comply from March 2024, the point at which Apple actually opened iOS in the EU — and in Japan by the Mobile Software Competition Act, which entered into force on 18 December 2025 and which Apple supports from iOS 26.2. Without those two regimes, neither store could exist on iPhone at all.

Skich positions itself as a games-focused iOS marketplace in the EU. Its public pitch leans on discovery: the swipe-to-match recommendation system, social playlists, and an activity feed showing what your friends play. On the commercial side, Skich has publicly described charging a 15% commission on purchases and in-app purchases made through the store — half of Apple’s headline 30% on the App Store. It began onboarding titles around GDC in spring 2025.

Onside describes itself as an alternative iOS marketplace serving the EU (excluding the UK) and, since 17 February 2026, Japan. Its angle is partly catalogue breadth within categories the App Store keeps at arm’s length — its own documentation advertises “broader categories (for example: mature-audience apps, crypto, or gaming), where they are legally compliant and appropriately age-gated” — and partly commercial terms: Onside’s developer docs state that “payments processed through Onside are subject to a 10% commission”, with no separate payout fee. On speed, be precise about what is actually promised: your build still has to clear either App Store Review or Apple’s Notarization first, and Onside’s own publishing guide says that after you hit publish, “this review can take up to 24 hours” — a fast second step, not a bypass of Apple’s.

A measured caveat: the alt-store space moves fast, public numbers are thin, and both companies are pitching themselves as much as describing a settled reality. Treat install figures, “matched” gamer counts, and category-breadth claims as positioning until you see them in your own dashboards — and note that neither store publishes audience data at all, so nobody can tell you the size of the shelf you’d be listing on. What’s solid is the structural fact — games-focused iOS storefronts now legally exist in the EU and Japan, competing on discovery and terms rather than scale.

How they fit next to the rest of the alt-store map

Games-only stores are not a replacement for the broader alternative-distribution landscape — they’re a slice of it. The fuller picture, which we lay out in the alternative app stores pillar, includes general-purpose DMA marketplaces (Aptoide, AltStore PAL), platform-holder plays like the Epic Games Store going mobile self-publishing, and the Android-side OEM app stores that carry enormous volume in Asia and Latin America.

Where do Skich and Onside sit in that map? They occupy the curated, discovery-led, iOS-DMA niche. They’re not chasing the volume an OEM preload deal delivers in Indonesia or Brazil; they’re chasing the quality of a self-selected, games-hungry iOS audience in wealthy markets where Apple’s install base is large and ARPU is high. That’s a deliberately narrower bet than Aptoide’s or AltStore’s. Aptoide itself has actually converged on the same games-only positioning on iOS — unlike its general-purpose Android catalogue — and paired it with the first Apple-approved native IAP on the platform; see our breakdown of Aptoide’s iOS marketplace for how its 10-20% commission model stacks up against Skich’s and Onside’s.

One cost you have to model on any iOS-DMA marketplace, including these, is Apple’s core-technology charge — and it is mid-transition, so check which version applies to your account. Apple’s documentation still describes the Core Technology Fee as “€0.50 for each first annual install per year over a one million threshold”, while also stating that Apple “will transition from the Core Technology Fee (CTF) to the CTC on digital goods or services” under a single EU business model. That successor, the Core Technology Commission, is 5% of digital sales — the rate Apple already applies to alternative marketplaces in Japan. We ran the break-even maths in what the Core Technology Fee actually costs a studio, and the headline applies here: the CTF rewards high-ARPU titles and punishes high-volume, low-monetisation ones. A games-only store’s high-intent audience helps on the ARPU side, but if your title is free, ad-monetised and install-heavy, run the numbers before you commit.

The operational reality for a publisher

The temptation with a discovery-led store is to treat it as a low-effort experiment — flip a build, list it, see what happens. That’s the same trap we warn studios away from with every alt-store. A games-only marketplace is still a real channel with its own integration surface. If you’ve already decided Onside is worth a shot, our step-by-step guide to publishing on Onside takes the operator’s view: what Apple gates, what the submission flow looks like, and what the stacked take-rate actually is.

The build. Distributing through an iOS marketplace means an alternative distribution build, the marketplace’s own SDK or notarisation flow, and (for in-app purchase) its payment integration rather than StoreKit. The delta from your App Store build is smaller than the Android-OEM SDK constellation, but it isn’t zero, and it has to be maintained as Apple’s entitlements evolve. Our third-party iOS marketplace checklist covers the entitlements, Notarization, and token sequence in order.

The merchandising. This is the part publishers underrate on discovery-led stores. A swipe-to-match or playlist-driven surface rewards good store assets — short-form video, sharp capsule art, a hook that reads in a second. If you port your App Store listing verbatim, you’re under-using the exact thing that makes a games-only store worth being on. The channel rewards merchandising effort in a way a search-driven store doesn’t.

The reporting. Each store has its own console, payout cadence, and analytics. With two or three of these, you’ve got two or three reconciliation flows — manageable, but a real ongoing cost, and the part that quietly decays when nobody owns it.

The honest summary: a games-only store is a good fit if your title benefits from curation and you’ll do the merchandising work, and a poor fit if you were hoping to list-and-forget. For the underlying integration and payout mechanics across channels, our distribution practice overview walks through what each store actually demands.

A pragmatic take for 2026

If you’re a publisher weighing Skich, Onside, or the next games-only store to launch, here’s the shape of a sensible decision:

1. Match the store to the title, not the title to the store. A high-intent, curation-led audience favours games with strong hooks and clear genre identity. A generic mid-core title with weak store assets will underperform on a discovery surface as surely as it does in App Store search.
2. Model Apple’s core-technology charge first. On any iOS-DMA store, the CTF — or the 5% Core Technology Commission that Apple says will replace it — can flip your unit economics. Do that maths before the integration sprint, not after.
3. Commit to the merchandising. The whole point of a games-only store is discovery. Half-hearted store assets waste the channel’s main advantage.
4. Treat it as a real channel, with an owner. One person responsible for the listing, the assets, the reporting. Not a shared back-office afterthought.
5. Watch Japan. Onside being live in Japan since February 2026, under a Mobile Software Competition Act that only entered into force on 18 December 2025, is a signal: the EU’s DMA template is being copied, and the games-only model travels with it. The publishers who learn the mechanics now will be a quarter ahead when the next jurisdiction opens.

Games-only stores won’t replace your App Store and Play presence in 2026. But for the right title, they’re a high-intent, lower-commission shelf that didn’t exist two years ago — and being early on a discovery-led channel is worth more than being late on a crowded one.

FAQ

What is a games-only app store?

A games-only app store is a third-party marketplace that lists only games, rather than being a general-purpose catalogue with games as one category among many. On iOS, stores like Skich and Onside exist because the EU’s Digital Markets Act and Japan’s Mobile Software Competition Act force Apple to allow alternative marketplaces. The advantage for publishers is a smaller competitive field and a pre-qualified, games-hungry audience.

How is Skich different from the Apple App Store?

Skich is a games-focused iOS marketplace in the EU, built around discovery features the App Store can’t ship — a swipe-to-match recommendation system, social playlists, and a friends-activity feed. It has publicly described a 15% commission on purchases and in-app purchases, against Apple’s headline 30%. It is a curated games shelf, not a general-purpose store.

What markets do Skich and Onside cover?

Skich launched its games-focused iOS marketplace in the EU. Onside operates in the EU excluding the UK and, since 17 February 2026, Japan, where alternative iOS marketplaces are enabled by the Mobile Software Competition Act rather than the DMA. Both are iOS-only and confined to jurisdictions where regulation forces Apple to permit third-party stores.

Do I still have to pay Apple’s Core Technology Fee on these stores?

There is an Apple charge, yes, but check which one. Apple’s documentation still describes the Core Technology Fee as €0.50 per first annual install above one million, while also saying Apple will transition the EU to a single business model in which the 5% Core Technology Commission replaces it. The per-install CTF favours high-ARPU titles and hurts high-volume, low-monetisation games; the commission model inverts that. Model whichever applies to your account before committing. We break down the maths in what the Core Technology Fee costs a studio.

Are games-only app stores worth it for a small studio?

For the right title, yes. The curated, discovery-led model gives a mid-tier game a realistic shot at visibility that App Store search rarely offers, and the lower commission helps. The caveats are that you must invest in store merchandising to use the discovery surface, and you must model Apple’s core-technology charge in whichever form applies to you. It is a poor fit if you were hoping to list and forget.

Will more games-only stores appear in 2026 and beyond?

Very likely. The regulatory infrastructure that allows them — the EU’s DMA and Japan’s Mobile Software Competition Act — is being copied in spirit by other jurisdictions, and the games-only model travels with it. Publishers who learn the mechanics of curated stores like Skich and Onside now are positioning themselves for the next market that opens.
