Stop guessing which keywords to target. Kōmori gives you real App Store data, rank tracking, and competitor insights so you can grow organic downloads without hiring an agency.

Kōmori covers every part of App Store optimization in one native macOS app. No spreadsheets, no browser tabs.
Find the exact terms your users search for. Every keyword comes with a volume score, a difficulty score, and the top 3 apps currently ranking for it. You always know where to focus.
See where your app ranks for every keyword, every day. Kōmori keeps 30 days of history so you can spot trends, measure the impact of metadata changes, and catch drops before they hurt.
See exactly which keywords your top competitors rank for and what is driving their downloads. Find gaps they are missing and keywords your app is positioned to take.
Track top charts across 33 App Store countries and 25+ categories. See which apps are rising, spot seasonal trends, and understand where your category is heading.
Monitor your ratings and reviews across 90+ countries. Understand what users love, what they want fixed, and how your sentiment compares to competitors.
Kōmori surfaces keyword opportunities you would miss manually, including hidden keywords Apple does not surface in search, and scores your overall ASO health in seconds.
Enterprise ASO tools charge hundreds monthly. Kōmori gives you the same insights at indie-friendly prices.
See all plansNative macOS app that integrates seamlessly with your development process. No web dashboards, no subscriptions to manage outside your Mac.
Complex ASO metrics simplified into clear recommendations. Focus on building your app, not becoming an ASO expert.

Three steps. Repeat monthly. Watch your organic downloads grow.
Run keyword research to discover high-volume, low-competition terms your app is not ranking for yet. Sort by ranking potential to focus on what moves the needle.
Rewrite your title, subtitle, and keyword field with data-backed choices. Kōmori's metadata tools respect Apple's character limits and flag duplicate keywords automatically.
Submit your update to Apple, then watch your rankings in Kōmori. Repeat the cycle monthly to compound your organic growth over time.
