Cha-Ching now syncs across your Macs. Install on a second Mac, sign in with the same Apple ID, and your connected accounts, API keys and revenue history are just there — nothing to reconnect, nothing to re-type. Everything syncs through Apple's own iCloud infrastructure (Keychain, CloudKit and iCloud Drive), the same mechanism Safari uses for saved passwords — never a Cha-Ching server. Also in this update: • Test Connection — check your API key against the real service before saving, instead of finding out later that a typo left you staring at $0.00. • Setup guides for Stripe, PayPal, Shopify and RevenueCat, built into the Add Account screen. • Shopify now asks for your store handle and shows .myshopify.com inline, so it is obvious what to paste. • Tap a payment notification to open the app. Tap an error notification to go straight to the account that needs fixing. • Local history raised from 100 payments to 5,000, so All Time totals are accurate. • The polling interval now takes effect immediately instead of on the next cycle. • Analytics tells you when payments in other currencies are excluded from a total.
