Pick your product, paste the page where a competitor sells the same thing, and the app reads that page a few times a day: their current and crossed-out prices, whether it is in stock, when. The table shows theirs next to yours with the gap; the moment one goes under you, drops, or comes back above, the alert lands in Telegram, Slack, Discord or e-mail. Any online store with a readable product page; marketplaces such as Amazon or eBay are not supported. The app never changes your prices.

• Their current and crossed-out prices next to yours, with the gap, per link
• Read a few times a day, with history per link and a log of every run
• Alerts when a competitor goes under you, drops, starts a sale or comes back
• Any online store with a readable product page; marketplaces not supported
• Nothing is written to your store: one permission, read products
