Astro

Astro is a native Mac App Store Optimization (ASO) tool that helps iOS developers discover the keywords their users are actually searching for and grow app downloads up to 10x faster. Astro pulls popularity data directly from Apple Search Ads, calculates how difficult it is to rank in the top 10 for any keyword, and suggests new keywords based on your competitors' rankings — all from a clean, minimal interface designed for daily research. It tracks unlimited keywords and apps with a fixed annual subscription (no per-keyword fees), updates rankings every day across 60+ App Store countries, includes DeepL-powered translation, and surfaces new reviews from every store worldwide. 90% of Astro users see an increase in App Store impressions within the first week of updating their metadata.
