Peak ASO is made by YK Labs, an independent studio in Québec City.

For an independent iOS app, App Store search is a channel that costs nothing per install, and the words that decide it fit in very little space: a 30-character name, a 30-character subtitle and a 100-character keyword field. Those words are often chosen once, by feel, and rarely revisited, because it is hard to see what a change actually did.

Peak ASO is meant to make those choices measurable for people who do their own marketing: which terms are searched, which ones an app can realistically reach, where it ranks today, what competitors win, and what users keep saying in reviews. Everything refreshes daily, in a tool sized and priced for one person or a small team.

• Indie iOS developers who ship and market their own apps.
• Small studios that run several apps and want one place for keywords, competitors and ads.
• Developers before launch: a research project can start from just a name, before the app has a listing.

• Keyword research — popularity, difficulty and an opportunity score for each term, computed from the App Store's public search data.
• Rank tracking — your position in the top 200 for every tracked keyword, every day, on the storefronts you choose.
• Competitors — their ranks on your keywords, review velocity, releases, and the keywords they rank for that you don't track yet.
• Reviews — recurring themes in your 1–2★ and 4–5★ reviews, so the complaints and the praise are easy to read.
• Metadata builder — fit your vocabulary into the 30-character name, the 30-character subtitle and the 100-character keyword field.
• Real installs — connect App Store Connect to see Apple's own daily download numbers next to your visibility.
• Apple Ads — create campaigns from your organic data (always created paused) and read keep / cut / add verdicts from real spend.
• AI assistants — an MCP server so Claude and other assistants can work with your ASO data.

Popularity, difficulty and download figures are estimates computed from public data. They are meant to compare options against each other, not to be read as Apple's own numbers.

Peak ASO includes an MCP (Model Context Protocol) server. Create an API key in Settings → Integrations and Claude, or any MCP-compatible assistant, can list your apps, read your keywords, rankings, competitors, reviews, insights, keyword ideas and metadata draft, and track or untrack keywords. Every call is scoped to your account, and a key can be revoked at any time.

Peak ASO itself is developed with Claude Code, Anthropic's coding agent.
