StoreSync: Metadata Management, Accelerated
Are you spending hours manually copying descriptions and keywords in the App Store Connect web interface? Does switching between 40+ localizations feel like a slow, repetitive nightmare?
StoreSync is the professional macOS tool designed specifically for developers and ASO specialists who value their time. Manage your app’s metadata at lightning speed, automate the routine.
KEY FEATURES
One-Click Version Sync
Stop the manual "copy-paste" cycle. Our "One-Click Sync" feature allows you to instantly transfer descriptions, keywords, promotional texts, and other fields from any existing version (Ready for Sale) to your new draft (Prepare for Submission). Choose specific fields or sync everything at once to save hours of work.
Advanced Localization Editor
Navigate through languages using a modern tabbed interface. StoreSync supports all App Store Connect locales. Add new languages directly within the app and start filling them in immediately without ever opening a browser.
Powered by Apple Intelligence (AI)
Leverage the power of on-device AI to optimize your App Store presence:
Rewrite with AI: Instantly rephrase descriptions to make them more engaging and persuasive.
Keyword Generation: Generate high-traffic keyword lists based on your app’s name and description.
Smart Limits: The AI automatically respects App Store character limits (30 for titles, 170 for promo text, 4000 for descriptions), helping you maximize every available byte.
Competitor Lookup & Analysis
Keep a close eye on the market. Analyze competitor apps directly within StoreSync:
Keyword Density: See which words they prioritize in their descriptions
Visual Strategy: View all screenshots
Freshness Tracking: Monitor how often they update their metadata
AI Strategy Insight: Let the system analyze a competitor’s description and provide a concise summary of their value proposition and target audience
KEYWORD ANALYZER
Take control of your app’s search visibility.
Real-Time Rank Tracking: Monitor your app’s organic position for any search query across 40+ storefronts

TECHNICAL EXCELLENCE
Diff Review Before Submission: StoreSync shows a detailed "Diff" (comparison) between what is currently live and your new changes. See exactly which words were added or removed before hitting the "Push" button.
Security First: Your App Store Connect API keys are stored exclusively in your macOS System Keychain. All data exchange happens directly between your Mac and Apple’s servers.
Sync History: Maintain a full log of every push and synchronization. Never lose track of when and why you made a specific metadata change.
WHO IS THIS FOR?
Indie Developers: Manage your own portfolio with ease, freeing up time for coding instead of marketing logistics.
ASO Managers: Quickly test hypotheses and update keywords across dozens of localizations simultaneously.
App Agencies & Studios: Seamlessly switch between client accounts and apps, maintaining perfect order in metadata deployments.
WHY NATIVE IS BETTER THAN WEB
Blazing Speed: A native macOS interface is dozens of times faster than any web page.
Real-Time Character Counting: Visual indicators and over-limit warnings (30 for Name/Subtitle, 100 for Keywords) are always visible.
Batch Editing: Update global fields like Copyright and Version strings across all localizations in one go.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Metrics Trend, rebuilt:
- Period switcher — 7D / 30D / 90D / 1Y. The chart now loads only the range you want instead of the full history.
- Real numbers, not percentages — downloads and impressions are plotted in absolute values, so you see actual counts instead of % of peak.
- Downloads / Impressions toggle — focus on one metric at a time.
- True release dates — release markers now use the actual App Store release date (not the version creation date) and only mark versions that actually shipped.
Richer release details — click a release marker to see the version's
- What's New text plus the metadata changes grouped by locale.
- Faster history backfill — missing days load in parallel batches with a visible progress counter, and zero-download days are cached permanently instead of being re-fetched every time.
