Best ASO tools for indie app developers (2026)

We make HappyKeywords, and it’s on this list. We’ve tried to be fair: every price comes from the company’s own pricing page, and each tool gets its strengths and its limits. If something is out of date, tell us and we’ll fix it.

What two years of each subscription adds up to is on Pay once vs. subscriptions.

We looked for tools a developer with one to ten apps would actually pay for, and checked four things: what the cheapest useful plan costs over a year, how many keywords and countries it includes, whether it helps you change your listing (not just watch ranks), and what happens to your data when you stop paying. How to choose an ASO tool for Mac explains each question.

A Mac app for App Store keywords. Add a keyword in English and it finds the local phrase in 50+ countries, with your rank, estimated demand and difficulty in each. An Audit scores each country and says what to fix first. It writes the name, subtitle and keyword field with the AI you already use (Claude Code, Codex, Gemini, Copilot, Grok, OpenCode or a free local model through Ollama) and uploads them to App Store Connect with Undo. Every change is saved with your ranks before and after it.
