Add an App Store Connect account for every client or company you work with. Storewatch groups their apps, shows one account at a time when you need it, and keeps each account’s money separate.

The AI sees every account you add, so you can compare clients or zoom in on one.
Pick an account and the dashboard, yesterday’s numbers, top countries and charts show only its apps. Pick “All accounts” to see everything together again.

Make groups like Games, In progress or one client’s apps, with apps from any of your accounts. Drag apps between groups in the app list, and pick a group in the Show menu to see just its numbers.

Apple pays every developer account separately, often to different companies. Storewatch shows each account’s next payout, its fiscal month and when it should arrive, instead of one misleading total.

Each account uses its own App Store Connect API key, created by the client’s Account Holder or an Admin. Give it a name, add the vendor number, and its apps appear.

Yes. App Store Connect keys belong to one developer account, so you add a key for each client or company. An Admin key is best: only Admin keys can turn on Apple's analytics reports and edit listings.
No. One license covers every account and app you add.
Yes, Chat and the MCP server see every account you've added, so you can compare clients. Choose which AI to use, or none, in Settings → AI.
Yes. Groups are yours, not Apple's: put any app in any group, whichever account it comes from. Pick the group in the Show menu and the dashboard, Daily Downloads and Territories add those apps up. Payouts still come per account, because that's how Apple pays.
Open Settings → Apps and turn the app off. It leaves the app list, totals and charts and stops syncing, but its data stays on your Mac and nothing changes in App Store Connect. Turn it back on any time.
No. Storewatch runs on your Mac and nothing is shared with anyone. Each client only gives you a key for their own account.
