What Slap Alert does instead

  1. Pay once

    Slap Alert is a one-time purchase, currently US$19, with no subscription. You can try it free for 7 days first, and one license works on all of your own Macs. A full refund is available within 14 days of buying.

  2. A note per Stripe sale

    A pixel monkey slaps a sticky note with who paid and how much. Slap Alert checks Stripe every 30 seconds with a restricted key (Charges: Read and Invoices: Read only). It is one note per sale, not a running total in the menu bar. You can turn the sound off. Setup is on the Stripe page.

  3. A different Mac, and other sources

    Slap Alert needs macOS 14 Sonoma or later. It also watches Paddle, RevenueCat and Shopify, and App Store sales arrive as one note each morning. Cha-Ching's page says it needs macOS 15.0 or later.
