HOW IT WORKS 1. Find something sold out and share the link to Nudge (right from Safari's share sheet, or paste it in). 2. Nudge reads the page and shows you every size and color, in stock or not. 3. Pick the exact one you want. 4. We check it every few minutes, and send you a push notification the moment it's back — with a direct link to buy. That's it. No account, no email signup - just your device. BUILT FOR THE STORES THAT SELL OUT FAST Nudge currently watches Skims, Gymshark, Alo Yoga, Princess Polly, White Fox, Oh Polly, Brandy Melville, Meshki, Edikted, Motel Rocks, Tala, NVGTN, Oner Active, Doen, The Frankie Shop, Everlane, Cult Gaia, House of Sunny, AYBL, Represent, Realisation Par, Francesca's, and the Gap family — Old Navy, Gap, Banana Republic, and Athleta. More stores are added regularly. WHAT YOU GET • Per-size tracking - not just "is this item in stock," but "is size M, in this exact colorway, in stock" • A share-sheet extension so tracking something takes one tap from the store's own site or app • Push notifications the instant your size restocks • A tracker view that separates what's back in stock from what's still waiting • A buy button that jumps straight to checkout for that item • Pause or stop watching anything, anytime Stop refreshing the product page. Let Nudge do it for you. Terms of Use (EULA): https://shopwithnudge.com/terms Privacy Policy: https://shopwithnudge.com/privacy

Verdict
The clearest difference is ads: InStock at none against Nudge's shown. InStock also leads on chart position (#142 vs unranked). Nudge's advantage is update cadence (daily vs every 9 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
