The complete ASO toolkit, designed for daily use

Daily keyword rank
Track unlimited keywords across Apple App Store and Google Play. Up to 15 storefronts on Studio. Daily snapshots, never stale.
Competitor intelligence
Auto-discover competitors via "Customers Also Bought", keyword overlap, and AI-suggested matches. See exactly what they're testing.
Reviews & sentiment
Every review captured, classified by Claude for sentiment and themes. Spot crash spikes and feature requests as they happen.
Metadata diff alerts
Pixel-perfect screenshot diffing. Title, subtitle, description, icon, price — every change captured and surfaced instantly.
Smart alerts
In-app, email, Slack, push. Configure thresholds per app. Daily and weekly digests. Never miss a rank drop or a five-star review surge.
ASO Copilot
Claude Sonnet generates keyword opportunities, subtitle rewrites, and screenshot critiques tailored to your app and competitors.
Built for agencies
Multi-workspace, role-based access, white-label PDF reports, custom domains. Solo plans scale up without re-platforming.
Top 15 storefronts
US, UK, CA, AU, NZ, DE, FR, JP, KR, BR, MX, IN, ES, IT, NL — all the markets that matter for global indie growth.
Claude reads your app store data and tells you what to ship.
Stop guessing which keywords to chase or what to test in your subtitle. The Copilot analyzes your rankings, your competitors, and your category — then writes recommendations a senior ASO consultant would charge $5k for.
- Keyword opportunity scoring with rationale
- Subtitle and description rewrites with diff highlighting
- Screenshot critique using vision models
- Weekly narrative insights — what changed and why
Three of your top competitors (Yummly, Mealime, PlateJoy) added “weekly meal plans” to their subtitles in Q1 2026. Your app outranks them for related terms but doesn't target this exact phrase. Add it to your subtitle to capture the spillover.
