It started with frustration\u200a\u2014\u200aI was checking crypto prices dozens of times a day, across different websites, with no system at all. I wanted a simple tool that just works\u200a\u2014\u200anotifies you when it matters, tracks your portfolio, collects no data, requires no registration.

CryptoAlert is a Chrome extension and a mobile app\u200a\u2014\u200aavailable as a PWA (Progressive Web App)<\/strong>, meaning it installs directly from the browser, with no App Store and no Google Play. Two separate products, one idea. Payment in crypto, no forms, no subscriptions that renew without your knowledge. An AI that understands your portfolio and responds in seven languages.<\/p>\n I\u2019m writing about this publicly because I believe transparency builds trust. This isn\u2019t a corporate product<\/strong>\u200a\u2014\u200ait\u2019s a tool I use myself every\u00a0day.<\/p>\n Imagine you\u2019re sitting with your morning coffee, checking the price of Bitcoin. You open your phone, go to some website, see the price\u200a\u2014\u200aand close it. An hour later you do the same thing. Over and over\u00a0again.<\/p>\n CryptoAlert was built to change\u00a0that.<\/p>\n It\u2019s available in two separate forms that work independently of each\u00a0other.<\/p>\n Mobile and Web App (PWA)<\/strong>: On your phone, you install it like a regular app\u200a\u2014\u200ano App Store, no Google Play. Open the website in your browser, tap \u201cAdd to Home Screen\u201d and you\u2019re done. On Android, the browser will suggest installation automatically\u200a\u2014\u200aone tap is all it takes. On iOS, open the site in Safari, tap \u201cShare\u201d and \u201cAdd to Home Screen\u201d. Note\u200a\u2014\u200apush notifications on iOS require version 16.4 or later and only work when the app is added to your home\u00a0screen.<\/p>\n Chrome Extension:<\/strong> For those who prefer everything at hand on their computer\u200a\u2014\u200ainstall the extension from the Chrome Web Store<\/strong><\/a> with one click. The icon appears in your browser toolbar and gives you access to prices, alerts and your portfolio without opening a new tab. The extension runs in the background\u200a\u2014\u200arefreshing prices and sending notifications even when the browser is minimized.<\/p>\n When you open the app, you see your favorite cryptocurrency prices in real time. Bitcoin, Ethereum, BNB, Solana, XRP\u200a\u2014\u200awhatever you want to track. Each coin shows the current price, 24-hour change and a 7-day chart. At a glance, you know exactly what\u2019s happening with your portfolio.<\/p>\n But that\u2019s just the beginning.<\/p>\n You can set an alert\u200a\u2014\u200afor example \u201cnotify me when Bitcoin drops below $78,000\u201d. And you forget about it. The app watches for you. When the price hits your target\u200a\u2014\u200ayou get a notification. On laptop, a popup appears in the corner of your screen. On phone\u200a\u2014\u200aa push notification even when the app is closed and buried deep in the background.<\/p>\n Every alert has a built-in 30-minute cooldown\u200a\u2014\u200aif the price oscillates around the threshold and crosses it multiple times, you don\u2019t get a notification every time, just once every half hour. Markets can be volatile\u200a\u2014\u200ayour phone doesn\u2019t have to\u00a0be.<\/p>\n You also have a Portfolio tab where you enter how much of each coin you hold. The app continuously shows your total portfolio value in dollars\u200a\u2014\u200aalways visible, always up to date. You see immediately what you\u2019re worth\u200a\u2014\u200ano mental math, no opening an exchange.<\/p>\n Portfolio tab\u200a\u2014\u200atotal value updated in real\u00a0time<\/p>\n Here\u2019s where it gets really interesting\u200a\u2014\u200athe AI assistant.
