A stock price alert app that just emails you when the market moves
A stock price alert app watches the market for you and tells you the moment a stock or ETF reaches a price you care about. Computo does exactly that by email: set a target price, a percentage move, or a ratio between two symbols, and it emails you when the level hits — no app to open, no chart to babysit, unlimited alerts for a flat $5/month.
TL;DR
Computo is a stock price alert app for people who don't want another dashboard: set your levels once and get an email when the market hits them. Unlimited price, percentage, and ratio alerts on US stocks and ETFs, delivered inside your timezone windows, for $5/month — free for your first fifteen, no card required.

Illustrative example
What does a stock price alert app do?
A stock price alert app monitors quotes in the background and notifies you when a condition you set is met — a stock crossing a target price, an ETF dropping a set percentage, or a spread between two symbols reaching a level. The point is to stop you from staring at charts all day. Computo delivers those alerts by email instead of a push notification you'll miss, so the signal lands somewhere you actually read: price targets, percentage moves, and ratio rules across US stocks and ETFs.
What to look for in a stock price alert app
Three things separate a useful alert app from a noisy one. First, delivery you won't miss — email reaches you even when the app is closed, unlike an in-app banner. Second, alert types beyond a single price: percentage moves and ratios between two symbols catch setups a plain price target can't. Third, quiet hours — a good app knows your timezone and holds an overnight trigger until the morning instead of waking you at 3am. Computo does all three, with no cap on how many alerts you run.
How much should a stock price alert app cost?
Most alerting lives inside broker or charting platforms, where lifting a tiny free cap means paying $13–$60/month for tools you may not use. A dedicated stock price alert app should cost far less because it does one thing. Computo is $5/month flat — or $50/year — for unlimited alerts, an unlimited watchlist, and up to five brokerage portfolios with live totals. The free tier covers your first fifteen alerts with no credit card, so you can test the delivery before paying anything.
Why people choose Computo
Three things set Computo apart from every tool on this page. First, pricing that scales with you: start free with fifteen alerts, then one flat $5/month unlocks unlimited alerts, an unlimited watchlist, and up to five separate brokerage portfolios with live totals — no per-alert fees, no surprise tiers as your strategy grows. Second, alerts on your schedule: Computo knows your timezone and only delivers inside the windows you choose, so a level that breaks overnight reaches you in the morning — never a 3am email. Third, it keeps getting better: new alert types, portfolio tools, and delivery options ship regularly and land in every account automatically. You're not buying a frozen feature set — you're buying a tool actively built around watching the market by email.
Frequently asked questions
- Is there a free stock price alert app?
- Yes. Computo's free tier includes up to fifteen active alerts on US stocks and ETFs with no credit card required. You get price, percentage, and ratio alerts delivered by email. When you outgrow fifteen, Pro is $5/month for unlimited alerts — cheaper than the alerting add-ons bundled into most broker and charting platforms.
- Do I need to install an app to get stock price alerts?
- No. Computo is a web app that sends alerts by email, so there's nothing to install and nothing to keep open. You set your targets once in the browser and close the tab; when a US stock or ETF hits your price, moves a set percentage, or a ratio triggers, the alert lands in your inbox on your own timezone.
- Which markets does the stock price alert app cover?
- Computo covers US-listed stocks and ETFs. You can set price-target alerts, percentage-move alerts, and ratio alerts between two symbols, then track them alongside up to five brokerage portfolios with live totals. Alerts are delivered by email inside the timezone windows you choose, so an overnight move reaches you in the morning rather than at 3am.
- How much does Computo cost for unlimited alerts?
- Computo Pro is $5/month or $50/year for unlimited active alerts on US stocks and ETFs. The free tier includes up to fifteen alerts with no credit card required.
