Runtab shows what you owe on each credit card where you already look: Lock Screen and Home Screen widgets on iPhone, and the menu bar on Mac. Each card's number is posted plus pending charges, so you see what you owe now, not only what has posted. Cards link through Plaid, read-only: your bank sign-in never reaches Runtab, and nothing can move money. Free for 14 days with one card, then $5 a month for every card you carry. No ads, no analytics SDKs.
