Newton

I'm Newton, a solo founder from Ontario.

I kept refreshing my Stripe dashboard to see if anyone had paid. An email or a phone buzz felt too small for the moment someone pays you for a thing you made. So I built Slap Alert: a pixel monkey hangs in the corner of your Mac, and when a sale comes in he swings down and slaps a sticky note on your screen with who paid and how much.

It works with Stripe (a read-only restricted key; full secret keys get refused), Paddle, Polar, Dodo Payments, RevenueCat and Shopify paid orders. App Store sales come as one note each morning, because Apple only reports sales once a day. Keys stay in your Mac's keychain and there's no account to make. Your own scripts can make him slap too, for free: drop a small JSON file in his Inbox folder.

US$12 launch price for the first 50 buyers through Nov 2, then US$19 once, no subscription, with a 7-day free trial and a full refund within 14 days. Stripe test mode and Paddle sandbox work, so you can watch a slap before your first real sale. Needs macOS 14 or later.
